The diploid genome of the only sclerotia-forming wild-type species in the genus Pleurotus -Pleurotus tuber-regium - provides insights into the mechanism of its biomass conversion from lignocellulose substrates

J Biotechnol. 2018 Oct 10;283:22-27. doi: 10.1016/j.jbiotec.2018.07.009. Epub 2018 Jul 9.


Pleurotus tuber-regium (Fr.) Singer, being a white-rot fungus, is widely used for food and medicine in the Asia-Pacific region. In this study, we sequenced and annotated the genome of a dikaryon P. tuber-regium wild strain to provide a better understanding of the carbohydrate-active enzymes (CAZymes) involved in the bio-conversion of lignocellulose to beta-glucan reserves in this sclerotia-forming Pleurotus mushroom with reference to enzyme participated in cellulosic compound breakdown and glucan reserve biosynthesis. The present genomic data provides new insights for lignocellulose bioconversion of white-rot fungus for the genus Pleurotus.
