Epigenetic and posttranslational regulation of nitrogen-induced autophagy in M. oryzae. Epigenetic and posttranslational regulation of nitrogen-induced autophagy in M. oryzae. Autophagic activity visualized by RFP-Atg8 signal in CM- or MM-N-cultured mycelia of the WT, OX, OX (H3M). and OX (Atg7M H3M) mutants. GFP-Gcn5 signal appeared in the strains carrying the overexpressed GCN5 gene. DIC, differential interference contrast. Bar = 5 μm. Meiling Liang et al. mSystems 2018; doi:10.1128/mSystems.00270-18
