I am excited to announce the publication of another mushroom genome this week. The mushroom Schizophyllum commune is an important model system for mushroom biology, development of genome was sequenced as part of efforts at the Joint Genome Institute and a collection of international researchers. The data and analyses from these efforts are presented in a publication appearing in Nature Biotechnology today.
Studies in mushrooms can have important impact on other research areas. They can be useful in biotechnology as protein biosynthesis factories for producing compounds or even as an edible delivery mechanism for new drugs. What we found in the analysis of this genome include clues to mechanisms of how white rotting fungi degrade lignin through analysis of enzyme families. We also saw evidence for extensive antisense transcription during different developmental stages suggesting some important clues as to how some gene regulation could impact or control developmental progression. Through gene expression comparison (by MPSS) a large number of transcription factors were shown to be differentially regulated during sexual development. A knockout out two of these (fst3 and fst4) resulting in changes in ability to form mushrooms (fst4) or smaller mushrooms (fst3).
Several more interesting findings in this work that I hope to add back to this post when there is a little more time –
