Genetic diversity and population structure of a Traditional Chinese Medicine, Salvia miltiorrhiza (Danshen), based on transcriptome derived SSR markers.

Danshen (Salvia miltiorrhiza, Lamiaceae) is an herb medicine endemic to China. It has significant medicinal effects on treating cardiovascular diseases and neurasthenic insomnia. While many of the studies are focusing on its plant metabolics and developmental genetics, DanshenĂ¢€™s wild genetic resources and population structure has never been studied. Understanding its population genetics could clarify the effects of domestication on genetic diversity and also is necessary for selective breeding application. Here, we sampled 55 wild populations of Salvia miltiorrhiza covering its natural distribution in China and 5 domesticated populations to assess its germplasm resources and genetic structure. 45 novel eligible simple sequence repeats (SSR) loci were developed from an assembled transcriptome of Salvia milttiorrhiza. The allele number, Neighber-joining, mean overserved and expected heterozygosities, Hardy-Weinberg equilibrium, and probability of individual identification (PID) value were analyzed. The result showed with combinations of these microsatellite markers could be used as geo-regional population identification of Salvia milttiorrhiza in a high resolution, and provided a foundation for understanding its population structure and domestication history.
