Evolution of protective symbiosis in palaemonid shrimps (Decapoda: Caridea) with emphases on host spectrum and morphological adaptations.

Mol Phylogenet Evol 2021 May 10:107201. Epub 2021 May 10.

Simon F. S. Li Marine Science Laboratory, School of Life Sciences, The Chinese University of Hong Kong, Shatin, Hong Kong, China; Oxford University Museum of Natural History, Parks Road, Oxford OX1 3PW, UK. Electronic address:

Palaemonidae is the most speciose caridean shrimp family, with its huge biodiversity partially generated via symbiosis with various marine invertebrates. Previous studies have provided insights into the evolution of protective symbiosis in this family with evidence for frequent inter-phyla host switches, but the comprehensiveness of evolutionary pathways is hampered by the resolution of the previous phylogenetic trees as well as the taxon coverage. Furthermore, several critical issues related to the evolution of a symbiotic lifestyle, including the change in host spectrum and corresponding morphological adaptations, remain largely unresolved.

New Glomeromycotan Taxa, sp. nov. and gen. nov. et sp. nov. From Brazil, and gen. nov. From New Caledonia.

Front Microbiol 2021 23;12:655910. Epub 2021 Apr 23.

Departamento de Botânica e Zoologia, Universidade Federal do Rio Grande do Norte, Natal, Brazil.

Examination of fungal specimens collected in the Atlantic rain forest ecosystems of Northeast Brazil revealed many potentially new epigeous and semihypogeous glomerocarp-producing species of the phylum Glomeromycota. Among them were two fungi that formed unorganized epigeous glomerocarps with glomoid spores of almost identical morphology. The sole structure that distinguished the two fungi was the laminate layer 2 of their three-layered spore wall, which in spores of the second fungus crushed in PVLG-based mountants contracted and, consequently, transferred into a crown-like structure.

A revision of the species group in the millipede genus Chamberlin, 1918 (Diplopoda, Polydesmida, Xystodesmidae).

Zookeys 2021 13;1030:1-180. Epub 2021 Apr 13.

Virginia Tech, Department of Entomology, Blacksburg, Virginia 24061, USA Virginia Tech Blacksburg United States of America.

Millipedes in the family Xystodesmidae (Polydesmida) are often referred to as "colorful, flat-backed millipedes" for their bright aposematic coloration and tendency to form Müllerian mimicry rings in the Appalachian region. However, there are many species of Xystodesmidae that do not display colorful warning patterns, and instead have more cryptic appearances. Perhaps for this reason, groups such as the genus have remained understudied, despite containing a large number of undescribed species. Read More

Reenacting the Birth of a Function: Functional Divergence of HIUases and Transthyretins as Inferred by Evolutionary and Biophysical Studies.

J Mol Evol 2021 May 6. Epub 2021 May 6.

Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte, Brazil.

Transthyretin was discovered in the 1940s, named after its ability to bind thyroid hormones and retinol. In the genomic era, transthyretins were found to be part of a larger family with homologs of no obvious function, then called transthyretin-related proteins. Thus, it was proposed that the transthyretin gene could be the result of gene duplication of an ancestral of this newly identified homolog, later found out to be an enzyme involved in uric acid degradation, then named HIUase (5-hydroxy-isourate hydrolase).

Myoglobin primary structure reveals multiple convergent transitions to semi-aquatic life in the world's smallest mammalian divers.

Elife 2021 May 5;10. Epub 2021 May 5.

Department of Biological Sciences, University of Manitoba, Winnipeg, Canada.

The speciose mammalian order Eulipotyphla (moles, shrews, hedgehogs, solenodons) combines an unusual diversity of semi-aquatic, semi-fossorial, and fossorial forms that arose from terrestrial forbearers. However, our understanding of the ecomorphological pathways leading to these lifestyles has been confounded by a fragmentary fossil record, unresolved phylogenetic relationships, and potential morphological convergence, calling for novel approaches. The net surface charge of the oxygen-storing muscle protein myoglobin (), which can be readily determined from its primary structure, provides an objective target to address this question due to mechanistic linkages with myoglobin concentration.

A Phylogeny-Informed Analysis of the Global Coral-Symbiodiniaceae Interaction Network Reveals that Traits Correlated with Thermal Bleaching Are Specific to Symbiont Transmission Mode.

mSystems 2021 May 4;6(3). Epub 2021 May 4.

Integrative Research Center, Field Museum of Natural History, Chicago, Illinois, USA

The complex network of associations between corals and their dinoflagellates (family Symbiodiniaceae) are the basis of coral reef ecosystems but are sensitive to increasing global temperatures. Coral-symbiont interactions are restricted by ecological and evolutionary determinants that constrain partner choice and influence holobiont response to environmental stress; however, little is known about how these processes shape thermal resilience of the holobiont. Here, we built a network of global coral-Symbiodiniaceae associations, mapped species traits (e. Read More

Evolving origin-of-transfer sequences on staphylococcal conjugative and mobilizable plasmids-who's mimicking whom?

Nucleic Acids Res 2021 May 3. Epub 2021 May 3.

Curtin Health Innovation Research Institute, Curtin University, Perth, WA 6102, Australia.

In Staphylococcus aureus, most multiresistance plasmids lack conjugation or mobilization genes for horizontal transfer. However, most are mobilizable due to carriage of origin-of-transfer (oriT) sequences mimicking those of conjugative plasmids related to pWBG749. pWBG749-family plasmids have diverged to carry five distinct oriT subtypes and non-conjugative plasmids have been identified that contain mimics of each.

Extreme Morphology, Functional Trade-offs, and Evolutionary Dynamics in a Clade of Open-Ocean Fishes (Perciformes: Bramidae).

Integr Org Biol 2021 16;3(1):obab003. Epub 2021 Feb 16.

Biology Department, Morrill Science Center, University of Massachusetts, 611 North Pleasant Street, Amherst, MA 01003, USA.

When novel or extreme morphologies arise, they are oft met with the burden of functional trade-offs in other aspects of anatomy, which may limit phenotypic diversification and make particular adaptive peaks inaccessible. Bramids (Perciformes: Bramidae) comprise a small family of 20 extant species of fishes, which are distributed throughout pelagic waters worldwide. Within the Bramidae, the fanfishes ( and ) differ morphologically from the generally stout, laterally compressed species that typify the family. Read More

Division of Fish Genetics and Biotechnology, Fauclty of Fisheries Rangil, Ganderbal, SKUAST-Kashmir, India.

Common carp () is a commercial fish species valuable for nutritious components and plays a vital role in human healthy nutrition. The SOX (SRY-related genes systematically characterized by a high-mobility group HMG-box) encoded important gene regulatory proteins, a family of transcription factors found in a broad range of animal taxa and extensively known for its contribution in multiple developmental processes including contribution in sex determination across phyla. In our current study, we initially accomplished a genome-wide analysis to report the SOX gene family in common carp fish based on available genomic sequences of zebrafish retrieved from gene repository databases, we focused on the global identification of the Sox gene family in Common carp among wide range of vertebrates and teleosts based on bioinformatics tools and techniques and explore the evolutionary relationships.
