Sex-linked markers by genome-wide RAD sequencing to identify XX/XY Sex Chromosomes in the spiny frog (Quasipaa boulengeri)
<p><span>We use genotyping by sequencing as an approach to identify sex-linked markers in the spiny frog <i>Quasipaa boulengeri</i> with 43 wild-collected adults from a single site. The GBS methodology identified 2 loci on sex differences in allele frequencies, 50 loci on sex differences in heterozygosity, and 523 loci on male-limited occurrence, altogether associated with males heterogamety, indicating an XX-XY system. The sex specificity of five markers was further validated by PCR amplification with a large number of additional individuals from 26 various populations in this species. A total of 27 sex linkage markers were matched to Dmrt1 gene, a ubiquitous role in sex determination and differentiation from flies and nematodes to mammals. Chromosome 1, that harboring Dmrt1, has further been assigned to a highly potential candidate sex chromosome in anurans. Five sex-linked SNP makers explored 3 sex reversals out of 133 individuals here, sparsely showing sex reversal detected in wild amphibian populations. </span></p>

Quasipaa spinosa's genome assembly and annotation files
<p>Quasipaa spinosa, an Asian commercial Dicroglossidae species, is noted for the spiny chest of adult male individuals. Here, we report the first chromosomal level Q. spinosa genome employing PacBio long read sequencing and High-through Chromosome Conformation Capture (Hi‐C) technology. The total length of the final assembled genome was 2,839,292,578 bp, with contig N50 of 3.79 Mb and scaffold N50 of 327.44 Mb. Approximately 99.30% of the length of the assembled genome sequences were anchored to 13 chromosomes with the assistance of Hi-C reads. A total of 26,173 protein‐coding genes were predicted, and 95.98% of the genes were functionally annotated. The annotated genes covered a total of 92.10% of the complete vertebrate core gene set according to the BUSCO pipeline evaluation. Approximately 41 million years ago, Q. spinosa began to diverge from its dicroglossid sister taxon Nanorana parkeri. The Q. spinosa genome revealed obvious chromosomal fissions compared with Xenopus tropicalis, which likely represented a specific chromosome evolutionary history within frogs. Population analysis showed that Chinese Q. spinosa could be divided into eastern and western genetic clusters, with the western population showing higher diversity than the eastern population. The effective population size of Q. spinosa showed a continuously decreasing trend from one million years ago to 10,000 years ago. In summary, this study sheds light on Q. spinosa evolution and population differentiation, providing a valuable genomic resource for further biological and genetic studies on this species, and other closely related frog taxa.</p>
