Comparison of Genomes of Species from <i>Polemonium caeruleum</i> Complex and <i>Polemonium pulcherrimum</i> Complex Based on Repeatome and Chromosome Analysis.

ABSTRACT: Polemonium L. (Polemoniaceae) is a widespread genus native to subarctic and arctic regions of the Northern Hemisphere. The taxonomy and genome relationships within Polemonium are still unclear. We analyzed genomes of three species from each Polemonium caeruleum and Polemonium pulcherrimum complex using bioinformatic analysis by RepeatExplorer2/TAREAN pipelines of next-generation sequencing data. The repeatomes of all studied species were similar in type and number of repeats. Satellite DNAs (satDNAs) demonstrated high sequence identity within the studied species. FISH chromosome mapping of 45S rDNA, 5S rDNA, and two satDNAs Pol_C 33 and Pol_C 46 allowed us to construct the species karyograms and assess the genome diversity within the P. caeruleum complex
