Genome sequence of the fungus Pycnoporus sanguineus, which produces cinnabarinic acid and pH- and thermo- stable laccases.

ABSTRACT

Pycnoporus sanguineus, an edible mushroom, produces antimicrobial and antitumor bioactive compounds and pH- and thermo- stable laccases that have multiple potential biotechnological applications. Here we reported the complete genome of the species Pycnoporus sanguineus ACCC 51,180 by using the combination of Illumina HiSeq X Ten and the PacBio sequencing technology. The represented genome is 36.6 Mb composed of 59 scaffolds with 12,086 functionally annotated protein-coding genes. The genome of Pycnoporus sanguineus encodes at least 19 biosynthetic gene clusters for secondary metabolites, including a terpene cluster for biosynthesis of the antitumor clavaric acid. Seven laccases were identified, while 22 genes were found to be involved in the kynurenine pathway in which the intermediate metabolite 3-hydroxyanthranilic acid were catalyzed by laccases into cinnabarinic acid. This study represented the third genome of the genus Pycnoporus, and wound facilitate the exploration of useful sources from Pycnoporus sanguineus for future industrial applications.
