Transcription factor that regulates asexual reproduction (PubMed:19661696). Binds the StuA-response elements (StRE) with the consensus sequence 5'-(A/T)CGCG(T/A)N(A/C)-3' at the promoters of target genes (By similarity). Required for appressorium-mediated infection of rice leaves due to its involvement in the mobilization of lipids and glycogen (PubMed:19661696). Leads to reduced conidiation and mycelial growth (PubMed:19661696). Delays the transfer of conidial glycogen and lipid droplets and decreases efficiency of appressorium-mediated invasion of rice leaves (PubMed:19661696). Belongs to the EFG1/PHD1/stuA family.
