Transcription factor that regulates asexual reproduction (By similarity). 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). Regulates the expression of several effector genes (AvrLm1, AvrLm6 and AvrLm4-7) during infection stage (PubMed:25727237). Expression is induced during mycelial growth and at 14 days after infection, corresponding to the development of pycnidia on oilseed rape leaves (PubMed:25727237). Alters growth in axenic culture and impairs conidia production and perithecia formation (PubMed:25727237). Abolishes the pathogenicity on oilseed rape leaves and results in a drastic decrease in expression of at least the three effector genes AvrLm1, AvrLm6 and AvrLm4-7, during infection (PubMed:25727237). Belongs to the EFG1/PHD1/stuA family. Extended N-terminus.
