Development of microsatellite markers in Garcinia paucinervis (Clusiaceae), an endangered species of karst habitats1

چکیده
PREMISE OF THE STUDY Microsatellite markers were developed for Garcinia paucinervis (Clusiaceae), an endangered and endemic tree species of karst habitats, to analyze its genetic diversity and genetic structure. METHODS AND RESULTS Using shotgun sequencing on an Illumina MiSeq platform, a total of 22 microsatellite primer sets were characterized, of which 17 were identified as polymorphic. For these polymorphic loci, the total number of alleles per locus ranged from two to 12 across 54 individuals from three populations. The observed and expected heterozygosities ranged from 0.000 to 1.000 and from 0.000 to 0.850, respectively. No pair of loci showed significant linkage disequilibrium. Three loci in one population deviated significantly from Hardy-Weinberg equilibrium (P < 0.05). Seven loci (JSL3, JSL5, JSL22, JSL29, JSL32, JSL39, and JSL43) were successfully amplified in G. bracteata. CONCLUSIONS These markers will be useful in studies on genetic diversity and population structure of G. paucinervis.

Genetic structure of an endemic tooth-carp fish, Aphanius farsicus from four different water bodies in the Maharlu Lake basin was investigated by applying five microsatellite markers. All of the five examined microsatellite loci showed polymor-phism pattern. A total of four alleles were detected at five microsatellite loci, with an average of 2.8 to 3.5 alleles per locus. Average values of obse...
