Whole-genome sequencing and analysis of two azaleas, Rhododendron ripense and Rhododendron kiyosumense.

DNA Res 2021 Jul 20. Epub 2021 Jul 20.

Kazusa DNA Research Institute, 2-6-7 Kazusa-Kamatari, Kisarazu, Chiba, 292-0818, Japan.

To enhance the genomics and genetics of azalea, the whole-genome sequences of two species of Rhododendron were determined and analyzed in this study: Rhododendron ripense, the cytoplasmic donor and ancestral species of large-flowered and evergreen azalea cultivars; and Rhododendron kiyosumense, a native of Chiba prefecture (Japan) seldomly bred and cultivated.

Comparison of Whole Genome Sequencing versus Standard Molecular Diagnostics for Species Identification in the Leishmania Viannia Subgenus.

Am J Trop Med Hyg 2021 Jul 16. Epub 2021 Jul 16.

Institute of Medical Science, University of Toronto, Toronto, Ontario, Canada.

The prognosis and treatment of New World tegumentary leishmaniasis is dependent on the infecting species, yet such species identification in the Leishmania Viannia subgenus poses a diagnostic challenge. Currently, speciation relies on standard molecular techniques such as restriction fragment length polymorphism (RFLP) analysis, and Sanger sequencing (SS). Whole-genome sequencing (WGS) is a robust and increasingly cost-efficient tool that may improve Leishmania species identification. Read More

Phylogeny and evolution of mycophagy in the Zygothrica genus group (Diptera: Drosophilidae).

Mol Phylogenet Evol 2021 Jul 10;163:107257. Epub 2021 Jul 10.

Department of Biological Sciences, Faculty of Science, Hokkaido University, Sapporo 060-0810, Japan. Electronic address:

Despite numerous phylogenetic studies on the family Drosophilidae, relationships among some important lineages are still poorly resolved. An example is the equivocal position of the Zygothrica genus group that is mostly comprised of the mycophagous genera Hirtodrosophila, Mycodrosophila, Paramycodrosophila, and Zygothrica. To fill this gap, we conducted a phylogenetic analysis by assembling a dataset of 24 genes from 92 species, including 42 species of the Zygothrica genus group mainly from the Palearctic and Oriental regions.

Characterization of transcriptomic response in ovules derived from inter-subgeneric hybridization in Prunus (Rosaceae) species.

Plant Reprod 2021 Jun 24. Epub 2021 Jun 24.

Graduate School of Life and Environmental Sciences, Kyoto Prefectural University, Kyoto, 619-0244, Japan.

Key Message: Characterization of hybrid seed failure in Prunus provides insight into conserved or lineage-specific hybrid incompatibility mechanisms in plant species. Postzygotic hybrid incompatibility resulting from a cross between different species involves complex mechanisms occurring at various developmental stages. Embryo arrest, followed by seed abortion, is the first stage of such incompatibility reactions and inhibits hybrid seed development. Read More

First description of freshwater mite Unionicola sauerensis sp. nov. infesting thick-shelled river mussel Unio crassus.

Dis Aquat Organ 2021 Jun 17;145:63-77. Epub 2021 Jun 17.

Clinical Division of Fish Medicine, University of Veterinary Medicine, 1210 Vienna, Austria.

A sample of 30 thick-shelled river mussels Unio crassus Philipsson (Unionida: Unionidae) was collected from the River Sauer in Luxembourg to acquire data on parasitic infestations of the mussels. Among other parasites, different development stages of freshwater mites were collected from the gills and the mantle of the mussels and were documented with bright-field, stereo, and confocal laser scanning microscopy and microscopic X-ray computed tomography. The retrieved data allowed a morphological description of larvae and female adults of the mites and assigning them to the genus Unionicola Haldeman (Trombidiformes: Unionicolidae) and the subgenus Pentatax Thor.

Phylogeographic analysis of shrubby beardtongues reveals range expansions during the Last Glacial Maximum and implicates the Klamath Mountains as a hotspot for hybridization.

Mol Ecol 2021 May 20. Epub 2021 May 20.

Department of Evolution, Ecology and Organismal Biology, The Ohio State University, Columbus, OH, USA.

Quaternary glacial cycles often altered species' geographic distributions, which in turn altered the geographic structure of species' genetic diversity. In many cases, glacial expansion forced species in temperate climates to contract their ranges and reside in small pockets of suitable habitat (refugia), where they were likely to interact closely with other species, setting the stage for potential gene exchange. These introgression events, in turn, would have degraded species boundaries, making the inference of phylogenetic relationships challenging. Read More

Integrative taxonomy uncovers a new Culicoides (Diptera: Ceratopogonidae) biting midge species from Thailand.

Acta Trop 2021 Aug 2;220:105941. Epub 2021 May 2.

Department of Biology, Faculty of Science, Mahasarakham University, Kantharawichai District, Maha Sarakham 44150, Thailand.

Fully understanding biodiversity often requires an integrated approach especially for small insects because species diagnostic morphological characters are limited. In this study, morphological characters and DNA barcodes were used to examine previously recognized genetically divergent lineages detected in the biting midge, Culicoides arakawae (Arakawa), from Thailand. Morphological examinations revealed that specimens belonging to one lineage are morphologically different from C. Read More

Molecular phylogeny, biogeography and character evolution of the montane genus Juss. (Bignoniaceae).

Plant Divers 2021 Feb 22;43(1):1-14. Epub 2020 Sep 22.

CAS Key Laboratory for Plant Diversity and Biogeography of East Asia, Kunming Institute of Botany, Chinese Academy of Sciences, Kunming 650201, China.

The complex orogeny of the Himalaya and the Qinghai-Tibet Plateau (QTP) fosters habitat fragmentation that drives morphological differentiation of mountain plant species. Consequently, determining phylogenetic relationships between plant subgenera using morphological characters is unreliable. Therefore, we used both molecular phylogeny and historical biogeographic analysis to infer the ancestral states of several vegetative and reproductive characters of the montane genus . Read More

Into the Chamber of Horrors: A proposal for the resolution of nomenclatural chaos in the Scaphiophryne calcarata complex (Anura: Microhylidae), with a new species-level phylogenetic hypothesis for Scaphiophryninae.

Zootaxa 2021 Mar 2;4938(4):zootaxa.4938.4.2. Epub 2021 Mar 2.

Department of Evolutionary Biology, University of Konstanz, Universitätsstrasse 10, 78464 Konstanz, Germany.

The genus Scaphiophryne (Anura: Microhylidae) contains at least nine species that, together with their probable sister genus Paradoxophyla, form the Madagascar-endemic subfamily Scaphiophryninae. Scaphiophryne are robust burrowing frogs with explosive breeding behavior and are characterized by a unique larval morphology, being intermediate between that of filter-feeding and generalized tadpole types. Based on tadpole morphology, the nominal subgenus Scaphiophryne can be distinguished from the subgenus Pseudohemisus, a clade occurring in arid biomes with a largely unsolved taxonomy and nomenclature.

Ticks Tick Borne Dis 2021 07 20;12(4):101688. Epub 2021 Feb 20.

Department of Parasitology, School of Chemistry and Molecular Biosciences, The University of Queensland, Brisbane, Queensland 4072, Australia. Electronic address:

Argasid systematics remains controversial with widespread adherence to the Hoogstraal (1985) classification scheme, even though it does not reflect evolutionary relationships and results in paraphyly for the main genera of soft ticks (Argasidae), namely Argas and Ornithodoros. The alternative classification scheme, proposed by Klompen and Oliver (1993), has problems of its own: most notably paraphyly of the subgenus Pavlovskyella and the controversial grouping together of the subgenera Alectorobius, Antricola, Carios, Chiropterargas, Nothoaspis, Parantricola, Reticulinasus and Subparmatus into the genus Carios. Recent phylogenetic analyses of 18S/28S rRNA sequences and mitochondrial genomes agree with the scheme of Klompen and Oliver (1993), with regard to the paraphyly of Pavlovskyella, placement of Alveonasus, Ogadenus, Proknekalia and Secretargas in the Argasinae and placement of Carios and Chiropterargas in the Ornithodorinae (Mans et al.
