Six Express Sequence Tag-Simple Sequence Repeat Primers Reveal Genetic Diversity in the Cultivars of Three Zanthoxylum Species.

ABSTRACT: Zanthoxylum (Sichuan pepper), with its rich cultivars, has long been widely cultivated in China for its unique seasoning and medicinal uses, but most of its cultivars have similar morphological characteristics. Therefore, we hypothesized that the genetic diversity of Zanthoxylum cultivars is low because of their apomixis and long cultivation history. In this study, we aimed to investigate the genetic diversity of three Zanthoxylum species on the cultivar level based on express sequence tag-simple sequence repeat (EST-SSR) primers. In total, 121 samples of three Zanthoxylum species (Z. bungeanum, Z. armatum and Z. piperitum) were collected from different areas in China for genetic diversity analysis. A total of six specificity and polymorphism EST-S
