ABSTRACT: Premise
Camellia reticulata, which is native to southwestern China, is an economically important plant belonging to the family Theaceae. We developed expressed sequence tag-simple sequence repeat (EST-SSR) markers for C. reticulata, which can be used to investigate its genetic diversity, population structure, and evolutionary history.Methods and results
We detected 4780 SSRs in C. reticulata from Camellia RNA-Seq data deposited in the National Center for Biotechnology Information's expressed sequence tags database (dbEST). Primer pairs for 70 SSR loci were designed and used for PCR amplification using 90 individuals from four populations of C. reticulata. Of these loci, 50 microsatellite markers were successfully identified, including 11 polymorphic markers. The allele number per locus ranged from two to seven (mean = 4.182), and the levels of observed and expected heterozygosity ranged from 0.044 to 0.567 and from 0.166 to 0.642, respectively. Eleven primer pairs amplified PCR products in three other species of Camellia (C. saluenensis, C. pitardii, and C. yunnanensis).Conclusions
The set of microsatellite markers developed here can be used to study the genetic variation and population structure of C. reticulata and related species and thereby help to develop conservation strategies for this species.
