However, gathering NGS data for organisms with very large genomes, such as amphibians, remains challenging because it is still unclear how the current methods perform. Here, we use the Genotyping-by-Sequencing (GBS) approach to generate SNP data for the genotyping of two amphibian species that are of conservation concern, the Sardinian brook salamander (<i>Euproctus platycephalus</i>) and the Italian stream frog (<i>Rana italica</i>). Both <i>E. platycephalus</i> and <i>R. italica</i> have very large genomes (5.53 Gb and >20 Gb, respectively) so genomic data are not available for either of them. We used 95 individual samples and one Illumina lane for each species, with an additional lane for <i>E. platycephalus</i>. After filtering, we obtained 961 and 854 high-coverage SNPs for <i>E. platycephalus</i> and <i>R. italica</i>, respectively. Our results suggest that GBS can serve as a reliable and cost-effective method for genotyping large amphibian genomes, including non-model species. 2019-01-02 11:48:52 conservation genomics frog newt Next Generation Sequencing SNPs whole genome duplications Ecology not elsewhere classified
