The assessment of genetic diversity and population structure of endemic Scutellaria yildirimlii (Lamiaceae) for conservation purposes

Scutellaria yildirimlii is an endangered perennial endemic species from Turkey and belongs to the family Lamiaceae, which has a high number of medicinal aromatic plants. It crucial determine genetic diversity population structure this for its conservation measures; therefore, 111 individuals five natural populations S. were investigated by using 15 inter simple sequence repeats (ISSR) primers. The percentage polymorphic loci (PPL), Nei?s gene (H), Shannon?s information index (I) at population-level determined as 93.9%, 0.183, 0.292 56.5%, 0.158, 0.242, respectively. analysis molecular variance (AMOVA) showed that there more variation within (84%) than among (16%). differentiation coefficient (GST = 0.144) was be moderate, confirmed level populations. Gene flow (Nm 2.984) exchange Pairwise distance values ranged 0.0219 0.0512. Mantel test revealed statistically significant positive correlation between geographical (r 0.493, p < 0.001). Unweighted Pair Group Method with Arithmetic Averages (UPGMA) dendrogram Principal Coordinate Analysis (PCoA) similar results. STRUCTURE (?K 3) K yielded maximum peaks 3 clusters. Based on findings, measures management presented.
