Genetic diversity in natural populations of Rhodiola species of different adaptation strategies

Representatives of the Crassulaceae family's genus Rhodiola are succulents, making them distinctive in a changing environment. One of the most significant tools for analyzing plant resources, in-cluding numerous genetic processes in wild populations, is the analysis of molecular genetic polymorphism. This work aimed to look at the polymorphisms of allelic variations of the Su-peroxide Dismutase (SOD) and Auxin Response Factors (ARFs) gene families, as well as the genetic diversity of five Rhodiola species using the retrotransposons-based fingerprinting approach. The multi-locus exon-primed intron crossing (EPIC-PCR) profiling approach was used to examine allelic variations in the SOD and ARF gene families. We implemented the inter-Primer Binding Site (iPBS) PCR amplification technique for genome profiling, which demonstrated a significant level of polymorphism in the Rhodiola samples studied. Natural populations of Rhodiola species have a great adaptation capacity to unfavorable environmental influences. The genetic variety of wild populations of Rhodiola species leads to their improved tolerance of opposing environmental circumstances and species evolutionary divergence based on the diversity of reproductive systems.
