The all-female Caucasian rock lizard Darevskia rostombekowi and other unisexual species of this genus reproduce normally via true parthenogenesis. Typically, diploid parthenogenetic reptiles exhibit some amount clonal diversity. However, allozyme data from D. have suggested that consists a single clone. Herein, we test hypothesis by evaluating variation at three variable microsatellite loci for 42 specimens four populations in Armenia. Analyses based on nucleotide polymorphisms each locus...
The parthenogenetic Caucasian rock lizard Darevskia armeniaca, like most other vertebrate species, originated through interspecific hybridization between the closely related sexual mixta and valentini. armeniaca was shown to consist of one widespread allozyme clone a few rare ones, but notwithstanding origin clonal diversity remains unclear. We conduct genomic analysis D. its parental species using microsatellite SNP markers identify lineages.Four microsatellite-containing loci were...
The extant reptiles are one of the most diverse clades among terrestrial vertebrates and a few groups with instances parthenogenesis. Due to hybrid origin parthenogenetic species, reference genomes parental species as well progeny indispensable explore genetic foundations reproduction. Here, we report on first genome assembly rock lizard Darevskia valentini, paternal for several lineages. novel was used in reconstruction comprehensive phylogeny Squamata inferred independently from 7369 trees...
Abstract Parthenogenesis has been discovered in a great number of reptiles, indicating that parthenogens can outcompete bisexual species and hybridize with them. This raises intriguing questions: how do parthenogenetic coexist gonochoristic relatives, what outcome does this coexistence produce? To answer these two questions, we studied relationships between male rock lizards, Darevskia valentini, armeniaca. We compared social sexual reactions males to females their own D. armeniaca vice...
Abstract Background The hybridization of female D. raddei and male valentini gave rise to the parthenogenetic Caucasian rock lizard Darevskia unisexualis . A previously identified genetic polymorphism in species consisted one common two allozyme clones. Analysis microsatellites single nucleotide polymorphisms (SNPs) from three yields estimates clonal diversity tests hypothesis a origin for Results Genotyping sequencing four microsatellite-containing loci 109 specimens , 17 valentini, 45...
Darevskia rock lizards include 29 sexual and seven parthenogenetic species of hybrid origin distributed in the Caucasus. All genus were formed as a result interspecific hybridization only four species. It remains unknown what are main advantages along with switching on reproduction evolution reptiles. Data whole transcriptome sequencing parthenogens their parental ancestors can provide value impact solving this problem. Here we have sequenced ovary tissue transcriptomes from unisexual lizard...
This study is performed in the frame of a bigger dedicated to genomics and transcriptomics parthenogenesis vertebrates. Among vertebrates, obligate was first described lizards genus Darevskia. In this genus, all found parthenogenetic species originated via interspecific hybridization. It remains unknown which genetic or genomic factors play key role generation organisms. Comparative transcriptomic analysis parthenogens their parental may elucidate problem. Darevskia valentini paternal for...
