Abstract
Agaricus bitorquis, an emerging wild mushroom with remarkable biological activities and a distinctive oversized mushroom shape, has gained increasing attention in recent years. Despite its status as an important resource of wild edible fungi, knowledge about this mushroom is still limited. In this study, we used the Illumina NovaSeq and Nanopore PromethION platforms to sequence, de novo assemble, and annotate the whole genome and mitochondrial genome (mitogenome) of the A. bitorquis strain BH01 isolated from Bosten Lake, Xinjiang Province, China. Using the genome-based biological information, we identified candidate genes associated with mating type and carbohydrate-active enzymes in A. bitorquis. Cluster analysis based on P450 of basidiomycetes revealed the types of P450 members of A. bitorquis. Comparative genomic, mitogenomic, and phylogenetic analyses were also performed, revealing interspecific differences and evolutionary features of A. bitorquis and A. bisporus. In addition, the molecular network of metabolites was investigated, highlighting differences in the chemical composition and content of the fruiting bodies of A. bitorquis and A. bisporus. The genome sequencing provides a comprehensive understanding and knowledge of A. bitorquis and the genus Agaricus mushrooms. This work provides valuable insights into the potential for artificial cultivation and molecular breeding of A. bitorquis, which will facilitate the development of A. bitorquis in the field of edible mushrooms and functional food manufacture.
