Funtion of MaSep1 in Metarhizium acridum and its Mechanism of Regulating Conidiation Pattern Shift

Conidiation necessary for filamentous fungal survival and dispersal proceeds in two fashions, namely, normal conidiation through conidiophores differentiated from hyphae and microcycle conidiation through conidial budding. Normal conidiation has been well studied, whereas mechanisms underlying microcycle conidiation are still largely unknown. Here, we report that a gene homologous to Sep1 in Schizosaccharomyces cerevisiae was involved in conidiation pattern shift in Metarhizium acridum. This indicated that MaSep1 played an important role in the growth, conidiation and stress resistance of Metarhizium acridum.
