Premise Of The Study:
Polymorphic microsatellite markers were developed for Artocarpus hypargyreus (Moraceae), a threatened species endemic to China, to investigate the genetic diversity and structure of the species.
Methods And Results:
Based on the transcriptome data of A. hypargyreus, 63 primer pairs were preliminarily designed and tested, of which 34 were successfully amplified and 10 displayed clear polymorphisms across the 67 individuals from four populations of A. hypargyreus. The results showed the number of alleles per locus ranged from three to 10, and the observed heterozygosity and expected heterozygosity per locus varied from 0.000 to 0.706 and from 0.328 to 0.807, respectively.
Conclusions:
These microsatellite markers will be useful in exploring genetic diversity and structure of A. hypargyreus. Furthermore, most loci were successfully cross-amplified in A. nitidus and A. heterophyllus, indicating that they will be of great value for genetic study across this genus.
