Development and characterization of nine microsatellites for an endangered tree, Pinus wangii (Pinaceae)1

UNLABELLED PREMISE OF THE STUDY Pinus wangii is an endemic and endangered species in southwestern China, and microsatellite primers were developed to characterize its genetic diversity and population structure. • METHODS AND RESULTS Using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) protocol, nine sets of microsatellite primers were developed in P. wangii. One population with 26 individuals of P. wangii, as well as 11 individuals each for two congeneric species, P. taiwanensis and P. squamata, were used to test their polymorphism and transferability. The number of alleles per locus ranged from one to seven with an average of 3.7, and the observed heterozygosity and expected heterozygosity ranged from 0 to 0.91 and 0 to 0.75, respectively. • CONCLUSIONS We developed nine sets of polymorphic microsatellite loci that are suitable for investigating genetic diversity and population structure of P. wangii, and these markers may be useful for other Pinus species.
