Abstract Rice blast is a serious threat to the safe production of grain crops such as rice and wheat. Sporulation, appressorium formation, and invasive growth of Magnaporthe oryzae are the key stages of the development and spread of rice blast epidemics. M. oryzae is a hemibiotrophic fungus that undergoes changes in available carbon sources during the infection cycle. Lipid is a major storage for M. oryzae spores and a major carbon source used in glycerol synthesis and turgor pressure generation in appressoria. The formation of a dense cell wall melanin layer is necessary for an appressorium to produce turgor and to be pathogenic. The plant cell wall is an important carbon source during the infection stage of M. oryzae. Transcription factors regulate gene expression in fungi and are key intermediates between the reception of external environmental signals and the control of development and pathogenicity in M. oryzae. The disease cycle of M. oryzae is controlled by some key transcription factors, such as sporulation by Cos1 and Hox2, appressorium formation by Sfl1, Hox7, and Vrf1, invasive growth by Mst12 and Mig1, and resistance to host basal immunity by Ap1 and Atf1. This review focuses on describing the key transcription factors of M. oryzae that regulate sporulation, appressorium formation, invasive growth, lipid metabolism, carbohydrate metabolism, melanin synthesis, oxidative response, and host basal immunity, as well as the working mechanism of the transcription factors. |
