摘要： The rice-S. rugosoannulata pattern is a rapidly growing agricultural practice for straw disposal and mushroom production in China. However, different S. rugosoannulata strains show a large variation in rice straw degradability. Here, we constructed a core collection of S. rugosoannulata containing 14 strains with rich genetic diversity. The molecular profiling of the lignocellulose degradability discrepancy of S. rugosoannulata strains was then explored using enzyme activity assays and transcriptome analysis. The results indicated that mycelial growth rate, lignocellulolytic enzyme activities, and rice straw degradability differed widely among the S. rugosoannulata core strains. The genes encoding lignin modifying and degrading auxiliary enzymes, oxidases, glycoside hydrolases, and detoxification proteins were differentially expressed between two representative S. rugosoannulata strains, resulting in differences in their lignocellulolytic enzyme activities and further causing differences in lignocellulose degradability. This study is useful to improve the production efficiency of S. rugosoannulata and promote the recycling of rice straw.
