The Coprinopsis cinerea Tup1 homologue Cag1 is required for gill formation during fruiting body morphogenesis.

ABSTRACT: The pileus (cap) of the fruiting body in homobasidiomycete fungi bears the hymenium, a layer of cells that includes the basidia where nuclear fusion, meiosis and sporulation occur. Coprinopsis cinerea is a model system for studying fruiting body development. The hymenium of C. cinerea forms at the surface of the gills in the pileus. In a previous study, we identified a mutation called cap-growthless1-1 (cag1-1) that blocks gill formation, which yields primordia that never mature. In this study, we found that the cag1 gene encodes a homologue of Saccharomyces cerevisiae Tup1. The C. cinerea genome contains another Tup1 homologue gene called Cc.tupA Reciprocal tagging of Cag1 and Cc.TupA with green and red fluorescent proteins revealed that the relative ratios of the amounts of the two Tup1
