The complete mitochondrial genome of the parthenogenetic Caucasian rock lizard Darevskia unisexualis (Squamata: lacertidae) contains long tandem repeat formed by 59?bp monomer.

ABSTRACT: The first complete mitochondrial genome sequence of parthenogenetic Caucasian rock lizard Darevskia unisexualis (Lacertidae family) is determined by hybrid assembly with Illumina HiSeq and PacBio RS II platforms. The circular 21.4 kbp mitogenome contains 13 protein-coding genes, 12S and 16S rRNA genes, 20 tRNAs, two pseudogenized tRNAs, and one long tandem repeats with 4.1 kbp length formed by 59?bp monomer repeated x70.6 times located before control region. This finding represents a new example of mitogenome variation in lizards of hybrid origin, providing fundamental data for following study of a unique hybridization system formed by parthenogenetic and bisexual species in the mountain steppe of central Armenia.

Project description:BACKGROUND:The parthenogenetic Caucasian rock lizard Darevskia armeniaca, like most other parthenogenetic vertebrate species, originated through interspecific hybridization between the closely related sexual Darevskia mixta and Darevskia valentini. Darevskia armeniaca was shown to consist of one widespread allozyme clone and a few rare ones, but notwithstanding the origin of clonal diversity remains unclear. We conduct genomic analysis of D. armeniaca and its parental sexual species using microsatellite and SNP markers to identify the origin of parthenogenetic clonal lineages. RESULTS:Four microsatellite-containing loci were genotyped for 111 specimens of D. armeniaca, 17 D. valentini, and four D. mixta. For these species, a total of 47 alleles were isolated and sequenced. Analysis of the data revealed 13 genotypes or presumptive clones in parthenogenetic D. armeniaca, including one widespread clone, two apparently geographically restricted clones, and ten rare clones. Comparisons of genotype-specific markers in D. armeniaca with those of its parental species revealed three founder-events including a common and two rare clones. All other clones appeared to have originated via post-formation microsatellite mutations in the course of evolutionary history of D. armeniaca. CONCLUSION:Our new approach to microsatellite genotyping reveals allele-specific microsatellite and SNP markers for each locus studied. Interspecies comparison of these markers identifies alleles inherited by parthenospecies from parental species, and provides new information on origin and evolution of clonal diversity in D. armeniaca. SNP analyses reveal at least three interspecific origins of D. armeniaca, and microsatellite mutations in these initial clones give rise to new clones. Thus, we first establish multiple origins of D. armeniaca. Our study identifies the most effective molecular markers for elucidating the origins of clonal diversity in other unisexual species that arose via interspecific hybridization.
