Project description:Lepista nuda is a wild edible fungus that is valued for its odor and taste. Recent studies identified intraspecific morphological and genetic differences in L. nuda. Although single-nucleotide polymorphisms (SNPs) are useful for revealing intraspecific differences, the traditional methods used for investigating SNPs are time consuming and expensive, and they only locate a limited number of SNPs. This study used a "restriction-site associated DNA" (RAD) method combined with high throughput sequencing to efficiently identify a large number of SNPs in two samples of L. nuda. A total of 7 and 9 billion bp of raw data were obtained from the two collections. A total of 712 SNPs were found. These SNPs will be useful for the further analysis of the genetic variation within L. nuda. The study also confirms that the RAD method can be used to identify SNPs in a nonmodel macrofungus for which a reference genome is unavailable.
