Autophagy is a common mechanism of self-degradation in eukaryotic cells and plays an important role in plant stress response. In addition, methyl jasmonate (MeJA), as an endogenous hormone widely existing in plants, can regulate the quality of fruits and vegetables after harvest and induce autophagic activity of fruits and vegetables. However, the molecular mechanism of MeJA regulating the autophagic activity of postharvest fruits and vegetables is still unclear.
Recently, Horticulture Research has launched (Advance Access) a research paper entitled “Interaction of methionine sulfoxide reductase B5 with SlMYC2 stimulates the transcription of MeJA-mediated autophagy-related genes in tomato fruit”. In this study, the previously constructed SlMYC2 was used to silence tomato fruit. Preliminary analysis showed that the transcription factor SlMYC2 was involved in regulating the transcription of MeJA-mediated postharvest tomato fruit autophagy related genes (SlATGs). And it was noticed that silencing SlMYC2 significantly reduced the increase in autophagy-related genes (SlATGs) expression induced by MeJA.
Collectively, these findings reveal the mechanism of SlMYC2 in SlATGs transcriptional regulation, providing insight into the mechanism of MeJA-mediated postharvest fruit quality regulation.
