Tremella fuciformis is a dimorphic fungus which can undertake the reversible transition between yeast and pseudohypha forms. G protein α subunit (Gα) carries different signals to regulate a variety of biological processes in eukaryotes, including fungal dimorphism. In this study, a novel Gα subunit encoded gene, TrGpa1, was firstly cloned from T. fuciformis. The TrGpa1 open reading frame has 1059 nucleotides, and encodes a protein which belongs to the group I of Gαi superfamily. Furthermore, the role of TrGpa1 in the T. fuciformis dimorphis...
