Development of Microsatellite Markers forFargesia denudata(Poaceae), the Staple-Food Bamboo of the Giant Panda

Premise of the study: There is a need for microsatellite primers to analyze genetic parameters of Fargesia denudata (Poaceae), the staple-food bamboo of the giant panda (Ailuropoda melanoleuca). Methods and Results: Using next-generation sequencing technology, we obtained a 75-Mb assembled sequence of F. denudata and identified 182 microsatellites. Primer pairs for 70 candidate microsatellite markers were selected and validated in four individuals, and 42 primer pairs generated reliable amplicons. Fourteen of 16 tested markers were found to be polymorphic in 72 individuals from four F. denudata populations. The number of alleles ranged from two to 19 per locus; the observed and expected heterozygosities ranged from 0 to 1 and from 0 to 0.87, respectively. The transferability of these 16 novel microsatellite markers was validated in five related species. Conclusions: These markers will be useful for examining the genetic diversity, genetic structure, and cloning of F. denudata, the staple-food bamboo of th...
