Transcriptional shifts in delignification-defective mutants of the white-rot fungus Pleurotus ostreatus.

Abstract excerpt

White-rot fungi efficiently degrade lignin and, thus, play a pivotal role in the global carbon cycle. However, the mechanisms of lignin degradation are largely unknown. Recently, mutations in four genes, namely wtr1, chd1, pex1, and gat1, were shown to abrogate the wood lignin-degrading ability of Pleurotus ostreatus. In this study, we conducted a comparative transcriptome analysis to identify genes that are...
