Project description:The evolution of complex multicellularity has been one of the major transitions in the history of life. In contrast to simple multicellular aggregates of cells, it has evolved only in a handful of lineages, including the animals, embryophytes, red and brown algae and fungi. Despite being a key step towards the evolution of complex organisms, the evolutionary origins and the genetic underpinnings of complex multicellularity are incompletely known. We constructed a reference atlas of mushroom formation based on developmental transcriptome data of six species and comparisons of >200 whole genomes, to elucidate the core genetic program of complex multicellularity and fruiting body development in mushroom-forming fungi (Agaricomycetes). Nearly 300 conserved gene families and >70 functional groups contained developmentally regulated genes from five to six species, covering functions related to fungal cell wall (FCW) remodeling, targeted protein degradation, signal transduction, adhesion and small secreted proteins (including effector-like orphan genes). Several of these families, including F-box proteins, expansin-like proteins, protein kinases, and transcription factors, showed expansions in Agaricomycetes, with from which many convergently expandedwere identified in multicellular plants and/or animals too, assuming convergent solutions to genetic hurdles imposed by complex multicellularity among independently evolved lineages. This study provides a novel entry point to studying mushroom development and complex multicellularity in one of the largest clades of complex eukaryotic organisms.

Project description:The transcription factors Hom2 and Fst4 were shown to be involved in mushroom development in the basidiomycete Schizophyllum commune. When the genes encoding Hom2 or Fst4 were deleted, no mushrooms formed. In this study we performed a genome-wide expression analysis on dikaryons of wild-type, delta-hom2 and delta-fst4.

When the genes encoding Hom2 or Fst4 were deleted, no mushrooms formed. In this study we performed a genome-wide expression analysis on dikaryons of wild-type, delta-hom2 and delta-fst4. A total of three samples were analyzed. One wild-type and two deletion strains (delta-hom2 and delta-fst4)
