Abstract:

Post-harvest diseases can lead to quality loss, energy decline, and shortened storage periods for fruits and vegetables. Numerous studies have shown that methyl jasmonate (MeJA) can be active in various growth and development pathways in plants, especially in the post-harvest storage and metabolite synthesis of fruits and vegetables. The core transcription factor MYC2 of JA can also participate in MeJA-mediated reactions to regulate plant activities. On the one hand, it directly regulates or indirectly synthesizes metabolites to regulate the post-harvest storage of plant fruits. On the other hand, MYC2 can assist plants in facing biotic and abiotic stresses by affecting related enzyme activities and gene expression levels. This review briefly summarizes the regulatory role of MeJA in post-harvest storage and metabolite synthesis in plants, aiming to provide inspiration for subsequent discoveries exploring additional mechanisms of MeJA action in plant growth and development.
