Abstract

Genetic diversity and differentiation among five populations of Calocedrus macrolepis in southwestern China were investigated using inter-simple sequence repeats (ISSR) markers. Low genetic diversity was revealed, with mean percentage of polymorphic loci at P=26.9% and average expected heterozygosity of H _E=0.1114. Low levels of genetic differentiation among populations were detected based on Nei's genetic diversity analysis (4.2%), Shannon's diversity index (2.7%), and AMOVA (4.1%). Pairwise genetic identity (I) values among populations ranged from 0.9899 to 0.9964, with a mean of 0.9932. There was no correlation between genetic and geographic distance among the populations studied. Possible genetic bottlenecks during Quaternary glaciations coupled with effects of genetic drift that shaped scattered and small populations were postulated to be the main reasons for the low genetic diversity in Calocedrus macrolepis.
