New microsatellite markers for Tricyrtis macrantha (Convallariaceae) and cross-amplification in closely related species.

Premise of the Study: Microsatellite markers were characterized in Tricyrtis macrantha (sect. Brachycyrtis, Convallariaceae), a vulnerable species endemic to Japan, to investigate its genetic diversity and population structure. •
Methods and Results: Eleven microsatellite markers were developed. The number of alleles per locus ranged from one to seven, and genetic diversity per locus ranged from 0.142 to 0.812. Four markers were successfully amplified in other species of sect. Brachycyrtis (T. ishiiana, T. ishiiana var. surugensis, and T. macranthopsis). •
Conclusions: The microsatellite markers can be used to investigate the genetic diversity and population structure of the vulnerable and endangered species of Tricyrtis sect. Brachycyrtis, to aid in the development of conservation strategies for each species.
