Isolation and characterization of 20 microsatellite loci for an important tropical tree <i>Shorea leprosula</i> (Dipterocarpaceae) and their applicability to <i>S. parvifolia</i>

Abstract

Abstract Shorea leprosula is an important timber tree in Southeast Asia. From a genomic library enriched for dinucleotide (CT) repeats, 20 polymorphic microsatellite markers were developed for this species. Polymorphism of these loci was evaluated in a sample of 24 adult individuals from a natural population. The number of alleles ranged from five to 15, and the observed heterozygosity ranged from 0.333 to 0.875. Probability of paternity exclusion, in the case where the mother is known, ranged from 0.285 to 0.784. These markers were also characterized for applicability in S. parvifolia ; 16 loci were successfully cross‐amplified and showed high levels of polymorphism.
