Abstract

Common valerian (Valeriana officinalis L.) is one of the most important medicinal plants, with a mild sedative, nervine, antispasmodic and relaxant effect. Despite a substantial number of studies on this species, the genetic diversity and population structure have not yet been analyzed. Here, we use a next-generation sequencing-based Diversity Array Technology sequencing (DArT-seq) technique to analyze Polish gene bank accessions that originated from wild populations and cultivars. The major and, also, the most astounding result of our work is the low level of observed heterozygosity of individual plants from natural populations, despite the fact that the species is widespread in the studied area. Inbreeding in naturally outcrossing species such as valerian decreases reproductive success. The analysis of the population structure showed the potential presence of a metapopulation in the central part of Poland and the formation of a distinct gene pool in the Bieszczady Mountains. The results also indicate the presence of the cultivated gene pool within wild populations in the region where the species is cultivated for the needs of the pharmaceutical industry, and this could lead to structural and genetic imbalances in wild populations.
