A key mechanism by which JAs execute these ecological functions is through the extensive remodelling of plant secondary metabolism. This review integrates and summarizes findings on the jasmonic acid signalling pathway, which initiates the biosynthesis of various secondary metabolites in different plant species. We specifically describe the core signalling module mediated by JA-Ile, which directly advances the biosynthesis of defensive chemicals like alkaloids, terpenoids and flavonoids. A major area of focus is on the molecular mechanisms which regulate this process and how Jasmonate ZIM-domain (JAZ) repressor proteins interact with a range of transcription factors such as MYCs, WRKYs, NACs and ERFs to co-ordinate and fine-tune defence responses and secondary metabolite biosynthesis. Moreover, this research shows that JA signalling maintains a balance between resource allocation for defence and growth, thereby managing the trade-off between plant growth and defence. Finally, we discuss the emerging potential of harnessing jasmonic acid pathways to enhance crop resilience against biotic stressors.
