Genetic diversity and population structure of the endangered species Paeonia decomposita endemic to China and implications for its conservation.

ABSTRACT:

Background

Paeonia decomposita, endemic to China, has important ornamental, medicinal, and economic value and is regarded as an endangered plant. The genetic diversity and population structure have seldom been described. A conservation management plan is not currently available.

Results

In the present study, 16 pairs of simple sequence repeat (SSR) primers were used to evaluate the genetic diversity and population structure. A total of 122 alleles were obtained with a mean of 7.625 alleles per locus. The expected heterozygosity (H_e) varied from 0.043 to 0.901 (mean 0.492) in 16 primers. Moderate genetic diversity (H_e = 0.405) among populations was revealed, with Danba identified as the center of genetic diversity. Mantel tests revealed a positive correl
