Highly polymorphic mitochondrial DNA and deceiving haplotypic differentiation: implications for assessing population genetic differentiation and connectivity.

BMC Evol Biol 2019 Apr 18;19(1):92. Epub 2019 Apr 18.

Royal Belgian Institute of Natural Sciences, Rue Vautier 29, B-1000, Brussels, Belgium.

Background: Hyperdiverse mtDNA with more than 5% of variable synonymous nucleotide sites can lead to erroneous interpretations of population genetic differentiation patterns and parameters (φ, D). We illustrate this by using hyperdiverse mtDNA markers to infer population genetic differentiation and connectivity in Melarhaphe neritoides, a NE Atlantic (NEA) gastropod with a high dispersal potential. We also provide a recent literature example of how mtDNA hyperdiversity may have misguided the interpretation of genetic connectivity in the crab Opecarcinus hypostegus. Read More

Variation in pigmentation gene expression is associated with distinct aposematic color morphs in the poison frog Dendrobates auratus.

BMC Evol Biol 2019 Apr 18;19(1):85. Epub 2019 Apr 18.

Department of Biology, East Carolina University, Greenville, North Carolina, USA.

Background: Color and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration are still poorly characterized, especially at the genomic level. Here we have taken a transcriptomics-based approach to elucidate the underlying genetic mechanisms affecting color and pattern in a highly polytypic poison frog. Read More

Phylogenetic mapping of scale nanostructure diversity in snakes.

BMC Evol Biol 2019 Apr 16;19(1):91. Epub 2019 Apr 16.

Laboratory of Artificial & Natural Evolution (LANE), Department of Genetics & Evolution, University of Geneva, Sciences III, 30, Quai Ernest-Ansermet, 1211, Geneva 4, Switzerland.

Background: Many species of snakes exhibit epidermal surface nanostructures that form complex motifs conferring self-cleaning properties, and sometimes structural iridescence, to their skin.

Results: Using confocal microscopy, we show that these specialised cells can be greatly elongated along their left-right axis and that different types of nanostructures are generated by cell borders and cell surface. To characterise the complexity and diversity of these surface gratings, we analysed scanning electron microscopy images of skin sheds from 353 species spanning 19 of the 26 families of snakes and characterised the observed nanostructures with four characters.

Alternated selection mechanisms maintain adaptive diversity in different demographic scenarios of a large carnivore.

BMC Evol Biol 2019 Apr 11;19(1):90. Epub 2019 Apr 11.

CIBIO/InBio - Centro de Investigação em Biodiversidade e Recursos Genéticos, Universidade do Porto, Campus de Vairão, 4485-661, Vairão, Portugal.

Background: Different population trajectories are expected to impact the signature of neutral and adaptive processes at multiple levels, challenging the assessment of the relative roles of different microevolutionary forces. Here, we integrate adaptive and neutral variability patterns to disentangle how adaptive diversity is driven under different demographic scenarios within the Iberian wolf (Canis lupus) range. We studied the persistent, the expanding and a small, isolated group within the Iberian wolf population, using 3 MHC class II genes (DRB1, DQA1, and DQB1), which diversity was compared with 39 microsatellite loci.

Analysis of the coding sequences of clownfish reveals molecular convergence in the evolution of lifespan.

BMC Evol Biol 2019 Apr 11;19(1):89. Epub 2019 Apr 11.

Leibniz Institute on Aging, Fritz Lipmann Institute, Jena, Germany.

Background: Standard evolutionary theories of aging postulate that reduced extrinsic mortality leads to evolution of longevity. Clownfishes of the genus Amphiprion live in a symbiotic relationship with sea anemones that provide protection from predators. We performed a survey and identified at least two species with a lifespan of over 20 years. Read More

Evidence of local adaptation in a waterfall-climbing Hawaiian goby fish derived from coupled biophysical modeling of larval dispersal and post-settlement selection.

BMC Evol Biol 2019 Apr 11;19(1):88. Epub 2019 Apr 11.

Department of Biological Sciences, Clemson University, Clemson, SC, 29634, USA.

Background: Local adaptation of marine and diadromous species is thought to be a product of larval dispersal, settlement mortality, and differential reproductive success, particularly in heterogeneous post-settlement habitats. We evaluated this premise with an oceanographic passive larval dispersal model coupled with individual-based models of post-settlement selection and reproduction to infer conditions that underlie local adaptation in Sicyopterus stimpsoni, an amphidromous Hawaiian goby known for its ability to climb waterfalls.

Results: Our model results demonstrated that larval dispersal is spatio-temporally asymmetric, with more larvae dispersed from the southeast (the Big Island) to northwest (Kaua'i) along the archipelago, reflecting prevailing conditions such as El Niño/La Niña oscillations. Read More

Mitochondrial genome evolution in parasitic plants.

BMC Evol Biol 2019 Apr 8;19(1):87. Epub 2019 Apr 8.

The Natural History Museum of Denmark, Faculty of Science, University of Copenhagen, Sølvgade 83, opg. S, DK-1307, Copenhagen K, Denmark.

Background: Parasitic plants rely on their host to cover their nutritional requirements either for their entire life or a smaller part of it. Depending on the level of parasitism, a proportional reduction on the plastid genome has been found. However, knowledge on gene loss and evolution of the mitogenome of parasitic plants is only available for four hemiparasitic Viscum species (Viscaceae), which lack many of the mitochondrial genes, while the remaining genes exhibit very fast molecular evolution rates.

Neuroanatomy of mud dragons: a comprehensive view of the nervous system in Echinoderes (Kinorhyncha) by confocal laser scanning microscopy.

BMC Evol Biol 2019 Apr 8;19(1):86. Epub 2019 Apr 8.

Smithsonian Institution, Smithsonian Marine Station at Fort Pierce, 701 Seaway Drive, Fort Pierce, Florida, 34949, USA.

Background: The Scalidophora (Kinorhyncha, Loricifera and Priapulida) have an important phylogenetic position as early branching ecdysozoans, yet the architecture of their nervous organ systems is notably underinvestigated. Without such information, and in the absence of a stable phylogenetic context, we are inhibited from producing adequate hypotheses about the evolution and diversification of ecdysozoan nervous systems. Here, we utilize confocal laser scanning microscopy to characterize serotonergic, tubulinergic and FMRFamidergic immunoreactivity patterns in a comparative neuroanatomical study with three species of Echinoderes, the most speciose, abundant and diverse genus within Kinorhyncha.

Micro-evolution of three Streptococcus species: selection, antigenic variation, and horizontal gene inflow.

BMC Evol Biol 2019 Mar 27;19(1):83. Epub 2019 Mar 27.

Kharkevich Institute for Information Transmission Problems, 19, Bolshoy Karetny per., Moscow, 127051, Russia.

Background: The genus Streptococcus comprises pathogens that strongly influence the health of humans and animals. Genome sequencing of multiple Streptococcus strains demonstrated high variability in gene content and order even in closely related strains of the same species and created a newly emerged object for genomic analysis, the pan-genome. Here we analysed the genome evolution of 25 strains of Streptococcus suis, 50 strains of Streptococcus pyogenes and 28 strains of Streptococcus pneumoniae. Read More

Phylogeography of Bellamya (Mollusca: Gastropoda: Viviparidae) snails on different continents: contrasting patterns of diversification in China and East Africa.

BMC Evol Biol 2019 Mar 21;19(1):82. Epub 2019 Mar 21.

College of Fisheries, Engineering Technology Research Center of Henan Province for Aquatic Animal Cultivation, Henan Normal University, Xinxiang, 453007, Henan, People's Republic of China.

Background: Species diversity is determined by both local environmental conditions that control differentiation and extinction and the outcome of large-scale processes that affect migration. The latter primarily comprises climatic change and dynamic landscape alteration. In the past few million years, both Southeast Asia and Eastern Africa experienced drastic climatic and geological oscillations: in Southeast Asia, especially in China, the Tibetan Plateau significantly rose up, and the flow of the Yangtze River was reversed.

On and off the rocks: persistence and ecological diversification in a tropical Australian lizard radiation.

BMC Evol Biol 2019 Mar 20;19(1):81. Epub 2019 Mar 20.

Division of Ecology and Evolution, Research School of Biology, and Centre for Biodiversity Analysis, The Australian National University, 46 Sullivans Creek Road, Acton, ACT, 2601, Australia.

Background: Congruent patterns in the distribution of biodiversity between regions or habitats suggest that key factors such as climatic and topographic variation may predictably shape evolutionary processes. In a number of tropical and arid biomes, genetic analyses are revealing deeper and more localised lineage diversity in rocky ranges than surrounding habitats. Two potential drivers of localised endemism in rocky areas are refugial persistence through climatic change, or ecological diversification and specialisation. Read More

Singleton molecular species delimitation based on COI-5P barcode sequences revealed high cryptic/undescribed diversity for Chinese katydids (Orthoptera: Tettigoniidae).

BMC Evol Biol 2019 Mar 14;19(1):79. Epub 2019 Mar 14.

Key Laboratory of Invertebrate Systematics and Application of Hebei Province, College of Life Sciences, Hebei University, Baoding, 071002, Hebei, China.

Background: DNA barcoding has been developed as a useful tool for species discrimination. Several sequence-based species delimitation methods, such as Barcode Index Number (BIN), REfined Single Linkage (RESL), Automatic Barcode Gap Discovery (ABGD), a Java program uses an explicit, determinate algorithm to define Molecular Operational Taxonomic Unit (jMOTU), Generalized Mixed Yule Coalescent (GMYC), and Bayesian implementation of the Poisson Tree Processes model (bPTP), were used. Our aim was to estimate Chinese katydid biodiversity using standard DNA barcode cytochrome c oxidase subunit I (COI-5P) sequences. Read More

Dictyostelium purpureum var. pseudosessile, a new variant of dictyostelid from tropical China.

BMC Evol Biol 2019 Mar 14;19(1):78. Epub 2019 Mar 14.

Engineering Research Center of Chinese Ministry of Education for Edible and Medicinal Fungi, Jilin Agricultural University, Changchun, 130118, People's Republic of China.

Background: Dictyostelid cellular slime molds (dictyostelids) are microscopic throughout their entire life cycle. The vegetative phase consists of single-celled amoeboid forms which live in the soil/leaf litter microhabitat of fields and forests along with animal dung, where they feed upon bacteria and other microbes, grow, and multiply until the available food supply is exhausted. When this happens, the amoeboid forms aggregate together in large numbers to form multi-celled pseudoplasmodia, which then give rise to fruiting bodies (sorocarps) that consist of supportive stalks and unwalled sori containing propagative spores.

Expression and regulatory asymmetry of retained Arabidopsis thaliana transcription factor genes derived from whole genome duplication.

BMC Evol Biol 2019 Mar 13;19(1):77. Epub 2019 Mar 13.

Genetics Program, Michigan State University, East Lansing, MI, 48824, USA.

Background: Transcription factors (TFs) play a key role in regulating plant development and response to environmental stimuli. While most genes revert to single copy after whole genome duplication (WGD) event, transcription factors are retained at a significantly higher rate. Little is known about how TF duplicates have diverged in their expression and regulation, the answer to which may contribute to a better understanding of the elevated retention rate among TFs.

A large close relative of C. elegans is slow-developing but not long-lived.

BMC Evol Biol 2019 Mar 11;19(1):74. Epub 2019 Mar 11.

Department of Biology, Institute of Ecology and Evolution, University of Oregon, Eugene, USA.

Background: Variation in body size is thought to be a major driver of a wide variety of ecological and evolutionary patterns, including changes in development, reproduction, and longevity. Additionally, drastic changes in natural context often have profound effects on multiple fitness-related traits. Caenorhabditis inopinata is a recently-discovered fig-associated nematode that is unusually large relative to other members of the genus, including the closely related model system C. Read More

Postcranial heterochrony, modularity, integration and disparity in the prenatal ossification in bats (Chiroptera).

BMC Evol Biol 2019 Mar 12;19(1):75. Epub 2019 Mar 12.

PANGEA Research Centre, School of Biological, Earth & Environmental Sciences, University of New South Wales, Sydney, NSW, 2052, Australia.

Background: Self-powered flight is one of the most energy-intensive types of locomotion found in vertebrates. It is also associated with a range of extreme morpho-physiological adaptations that evolved independently in three different vertebrate groups. Considering that development acts as a bridge between the genotype and phenotype on which selection acts, studying the ossification of the postcranium can potentially illuminate our understanding of bat flight evolution.

Systemic distribution of medullary bone in the avian skeleton: ground truthing criteria for the identification of reproductive tissues in extinct Avemetatarsalia.

BMC Evol Biol 2019 Mar 7;19(1):71. Epub 2019 Mar 7.

Paleontology, North Carolina Museum of Natural Sciences, Raleigh, NC, USA.

Background: Medullary bone (MB) is an estrogen-dependent, sex-specific tissue produced by female birds during lay and inferred to be present in extinct avemetatarsalians (bird-line archosaurs). Although preliminary studies suggest that MB can be deposited within most skeletal elements, these are restricted to commercial layers or hormonally treated male pigeons, which are poor analogues for wild birds. By contrast, studies in wild bird species noted the presence of MB almost exclusively within limb bones, spurring the misconception that MB deposition is largely restricted to these regions.

A comparison of reproductive isolation between two closely related oak species in zones of recent and ancient secondary contact.

BMC Evol Biol 2019 Mar 6;19(1):70. Epub 2019 Mar 6.

State Key Laboratory of Earth Surface Processes and Resource Ecology and MOE Key Laboratory for Biodiversity Science and Ecological Engineering, College of Life Sciences, Beijing Normal University, Beijing, 100875, China.

Background: Much of the debate over the evolutionary consequences of hybridization on genetic divergence and speciation results from the breakdown or reinforcement of reproductive barriers in secondary hybrid zones. Among hybrid populations established for different lengths of time following secondary contact, stronger reproductive barriers are generally expected to occur in zones with longer contact. However, in plants no detailed investigation of recent and ancient zones of secondary contact has been conducted despite the importance of such a comparative study. Read More

In silico simulations of occurrence of transcription factor binding sites in bacterial genomes.

BMC Evol Biol 2019 Mar 1;19(1):67. Epub 2019 Mar 1.

Department of Microbiology, University of Georgia, Athens, GA, USA.

Background: Interactions between transcription factors and their specific binding sites are a key component of regulation of gene expression. Until recently, it was generally assumed that most bacterial transcription factor binding sites are located at or near promoters. However, several recent works utilizing high-throughput technology to detect transcription factor binding sites in bacterial genomes found a large number of binding sites in unexpected locations, particularly inside genes, as opposed to known or expected promoter regions.

Joint effects of group sex-ratio and Wolbachia infection on female reproductive success in the terrestrial isopod Armadillidium vulgare.

BMC Evol Biol 2019 Feb 28;19(1):65. Epub 2019 Feb 28.

Laboratoire Ecologie et Biologie des Interactions, Equipe "Ecologie, Evolution, Symbiose", UMR CNRS 7267, Université de Poitiers, Bat B8-B35, 6 rue Michel Brunet, TSA 51106, F-86073, Poitiers, Cedex 9, France.

Background: In species that reproduce with sexual reproduction, males and females often have opposite strategies to maximize their own fitness. For instance, males are typically expected to maximize their number of mating events, whereas an excessive number of mating events can be costly for females. Although the risk of sexual harassment by males and resulting costs for females are expected to increase with the proportion of males, it remains unknown whether and how parasitic distorters of a host population's sex-ratio can shape this effect on the fitness of females.

The evolution of functional complexity within the β-amylase gene family in land plants.

BMC Evol Biol 2019 Feb 28;19(1):66. Epub 2019 Feb 28.

Department of Plant and Microbial Biology, University of Zürich, Zollikerstrasse 107, CH-8008, Zürich, Switzerland.

Background: β-Amylases (BAMs) are a multigene family of glucan hydrolytic enzymes playing a key role not only for plant biology but also for many industrial applications, such as the malting process in the brewing and distilling industries. BAMs have been extensively studied in Arabidopsis thaliana where they show a surprising level of complexity in terms of specialization within the different isoforms as well as regulatory functions played by at least three catalytically inactive members. Despite the importance of BAMs and the fact that multiple BAM proteins are also present in other angiosperms, little is known about their phylogenetic history or functional relationship. Read More

Background: The continuity of behavioral responses in the traits of offspring can be interpreted ambiguously because animal behavior can be transmitted from generation to generation genetically or can be trained. Inheritance of the sound signals characteristics in the absence of directional selection is of particular interest, and that was the purpose of the present work.

Results: Comparisons of distress signals of hybrids of the Tien Shan vole females Myodes centralis (Kyrgyzstan) and the bank vole males M. Read More

Genetic diversity of the Thao people of Taiwan using Y-chromosome, mitochondrial DNA and HLA gene systems.

BMC Evol Biol 2019 Feb 27;19(1):64. Epub 2019 Feb 27.

Molecular Anthropology and Transfusion Medicine Research Laboratory, Mackay Memorial Hospital, Taipei, Taiwan.

Background: Despite attempts in retracing the history of the Thao people in Taiwan using folktales, linguistics, physical anthropology, and ethnic studies, their history remains incomplete. The heritage of Thao has been associated with the Pazeh Western plains peoples and several other mountain peoples of Taiwan. In the last 400 years, their culture and genetic profile have been reshaped by East Asian migrants. Read More

Characterization of repeated DNA sequences in genomes of blue-flowered flax.

BMC Evol Biol 2019 Feb 26;19(Suppl 1):49. Epub 2019 Feb 26.

Engelhardt Institute of Molecular Biology, Russian Academy of Sciences, Moscow, Russia.

Background: Members of different sections of the genus Linum are characterized by wide variability in size, morphology and number of chromosomes in karyotypes. Since such variability is determined mainly by the amount and composition of repeated sequences, we conducted a comparative study of the repeatomes of species from four sections forming a clade of blue-flowered flax. Based on the results of high-throughput genome sequencing performed in this study as well as available WGS data, bioinformatic analyses of repeated sequences from 12 flax samples were carried out using a graph-based clustering method.

Transcriptomic analysis confirms differences among nuclear genomes of cryptic earthworm lineages living in sympatry.

BMC Evol Biol 2019 Feb 26;19(Suppl 1):50. Epub 2019 Feb 26.

Institute of Cytology and Genetics SB RAS, Pr. Lavrientieva 10, Novosibirsk, 630090, Russia.

Background: Many earthworm species demonstrate significant cryptic diversity, with several highly diverged mitochondrial lineages found within most of the taxa studied to date. The status of differences between these lineages on the nuclear level is still unclear. Because of widespread polyploidy in earthworms, most studies were limited to two nuclear loci, the ribosomal and the histone clusters. Read More

mtProtEvol: the resource presenting molecular evolution analysis of proteins involved in the function of Vertebrate mitochondria.

BMC Evol Biol 2019 Feb 26;19(Suppl 1):47. Epub 2019 Feb 26.

Center for Mitochondrial Functional Genomics, School of Life Science, Immanuel Kant Baltic Federal University, Kaliningrad, Russia.

Background: Heterotachy is the variation in the evolutionary rate of aligned sites in different parts of the phylogenetic tree. It occurs mainly due to epistatic interactions among the substitutions, which are highly complex and make it difficult to study protein evolution. The vast majority of computational evolutionary approaches for studying these epistatic interactions or their evolutionary consequences in proteins require high computational time. Read More

Evolution of plastid genomes of Holcoglossum (Orchidaceae) with recent radiation.

BMC Evol Biol 2019 Feb 26;19(1):63. Epub 2019 Feb 26.

State Key Laboratory of Systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences, Beijing, China.

Background: The plastid is a semiautonomous organelle with its own genome. Plastid genomes have been widely used as models for studying phylogeny, speciation and adaptive evolution. However, most studies focus on comparisons of plastid genome evolution at high taxonomic levels, and comparative studies of the process of plastome evolution at the infrageneric or intraspecific level remain elusive.

Population genomics of rapid evolution in natural populations: polygenic selection in response to power station thermal effluents.

BMC Evol Biol 2019 Feb 26;19(1):61. Epub 2019 Feb 26.

Rosenstiel School of Marine and Atmospheric Science, University of Miami, 4600 Rickenbacker Causeway, Miami, FL, 33149, USA.

Background: Examples of rapid evolution are common in nature but difficult to account for with the standard population genetic model of adaptation. Instead, selection from the standing genetic variation permits rapid adaptation via soft sweeps or polygenic adaptation. Empirical evidence of this process in nature is currently limited but accumulating. Read More

Detecting amino acid preference shifts with codon-level mutation-selection mixture models.

BMC Evol Biol 2019 Feb 26;19(1):62. Epub 2019 Feb 26.

Department of Biology, Carleton University, 1125 Colonel By Drive, Ottawa, K1S 5B6, Canada.

Background: In recent years, increasing attention has been placed on the development of phylogeny-based statistical methodologies for uncovering site-specific changes in amino acid fitness profiles over time. The few available random-effects approaches, modelling across-site variation in amino acid profiles as random variables drawn from a statistical law, either lack a mechanistic codon-level formulation, or pose significant computational challenges.

Results: Here, we bring together a few existing ideas to explore a simple and fast method based on a predefined finite mixture of amino acid profiles within a codon-level substitution model following the mutation-selection formulation. Read More

Selection shapes turnover and magnitude of sex-biased expression in Drosophila gonads.

BMC Evol Biol 2019 Feb 20;19(1):60. Epub 2019 Feb 20.

Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, MA, 02138, USA.

Background: Sex-biased gene expression is thought to drive the phenotypic differences in males and females in metazoans. Drosophila has served as a primary model for studying male-female differences in gene expression, and its effects on protein sequence divergence. However, the forces shaping evolution of sex-biased expression remain largely unresolved, including the roles of selection and pleiotropy. Read More

Evolution of CCL16 in Glires (Rodentia and Lagomorpha) shows an unusual random pseudogenization pattern.

BMC Evol Biol 2019 Feb 20;19(1):59. Epub 2019 Feb 20.

CIBIO, InBIO - Research Network in Biodiversity and Evolutionary Biology, Universidade do Porto, Campus de Vairão, Rua Padre Armando Quintas, 4485-661, Vairão, Portugal.

Background: The C-C motif chemokine ligand 16 (CCL16) is a potent pro-inflammatory chemokine and a chemoattractant for monocytes and lymphocytes. In normal plasma, it is present at high concentrations and elicits its effects on cells by interacting with cell surface chemokine receptors. In the European rabbit and in rodents such as mouse, rat and guinea pig, CCL16 was identified as a pseudogene, while in the thirteen-lined ground squirrel it appears to be potentially functional.

Sex ratios and bimaturism differ between temperature-dependent and genetic sex-determination systems in reptiles.

BMC Evol Biol 2019 Feb 18;19(1):57. Epub 2019 Feb 18.

MTA-PE Evolutionary Ecology Research Group, University of Pannonia, Pf. 158, Veszprém, 8201, Hungary.

Background: Sex-determining systems may profoundly influence the ecology, behaviour and demography of animals, yet these relationships are poorly understood. Here we investigate whether species with temperature-dependent (TSD) and genetic sex determination (GSD) differ in key demographic traits, using data from 181 species representing all major phylogenetic lineages of extant reptiles.

Results: We show that species with TSD exhibit significantly higher within-species variance in sex ratios than GSD species in three major life stages: birth or hatching, juvenility and adulthood. Read More

The role of genetic diversity in the evolution and maintenance of environmentally-cued, male alternative reproductive tactics.

BMC Evol Biol 2019 Feb 18;19(1):58. Epub 2019 Feb 18.

Department of Evolutionary and Population Biology, Institute for Biodiversity and Ecosystem Dynamics, University of Amsterdam, PO Box 94240, 1090 GE, Amsterdam, The Netherlands.

Background: Alternative reproductive tactics (ARTs) are taxonomically pervasive strategies adopted by individuals to maximize reproductive success within populations. Even for conditionally-dependent traits, consensus postulates most ARTs involve both genetic and environmental interactions (GEIs), but to date, quantifying genetic variation underlying the threshold disposing an individual to switch phenotypes in response to an environmental cue has been a difficult undertaking. Our study aims to investigate the origins and maintenance of ARTs within environmentally disparate populations of the microscopic bulb mite, Rhizoglyphus robini, that express 'fighter' and 'scrambler' male morphs mediated by a complex combination of environmental and genetic factors.

Identification and co-evolution pattern of stem cell regulator miR394s and their targets among diverse plant species.

BMC Evol Biol 2019 Feb 14;19(1):55. Epub 2019 Feb 14.

National Institute of Plant Genome Research, Aruna Asaf Ali Marg, New Delhi, 110067, India.

Background: Micro RNAs (miRNAs), a class of small non-coding RNAs, have been implicated in various aspects of plant development. miR394 is required for shoot apical meristem organization, stem cell maintenance and abiotic stress responses in Arabidopsis, where it functions by negatively regulating the transcript level of target LEAF CURLING RESPONSIVENESS (LCR), which is an F-box protein-coding gene. The evolutionary conservation of stem cell regulatory miR394-LCR module among plants remains elusive. Read More

Phyloproteomic and functional analyses do not support a split in the genus Borrelia (phylum Spirochaetes).

BMC Evol Biol 2019 Feb 13;19(1):54. Epub 2019 Feb 13.

UMR BIPAR, INRA, ANSES, Ecole Nationale Vétérinaire d'Alfort, Université Paris-Est, 94700, Maisons-Alfort, France.

Background: The evolutionary history of a species is frequently derived from molecular sequences, and the resulting phylogenetic trees do not include explicit functional information. Here, we aimed to assess the functional relationships among bacteria in the Spirochaetes phylum, based on the biological processes of 42,489 proteins in reference proteomes of 34 Spirochaetes species. We tested the hypothesis that the species in the genus Borrelia might be sufficiently different to warrant splitting them into two separate genera. Read More

Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Avenue, Cambridge, MA, 02138, USA.

Background: Germ lines are the cell lineages that give rise to the sperm and eggs in animals. The germ lines first arise from primordial germ cells (PGCs) during embryogenesis: these form from either a presumed derived mode of preformed germ plasm (inheritance) or from an ancestral mechanism of inductive cell-cell signalling (induction). Numerous genes involved in germ line specification and development have been identified and functionally studied. Read More
