Pan-Genomes Provide Insights into the Genetic Basis of Auricularia heimuer Domestication.

ABSTRACT: In order to reveal the genetic variation signals of Auricularia heimuer that have occurred during their domestication and to find potential functional gene families, we constructed a monokaryotic pan-genome of A. heimuer representing four cultivated strains and four wild strains. The pan-genome contained 14,089 gene families, of which 67.56% were core gene families and 31.88% were dispensable gene families. We screened substrate utilization-related genes such as the chitinase gene ahchi1 of the glycoside hydrolase (GH) 18 family and a carbohydrate-binding module (CBM)-related gene from the dispensable families of cultivated populations. The genomic difference in the ahchi1 gene between the wild and cultivated genomes was caused by a 33 kb presence/absence variat
