Jasmonates Coordinate Secondary with Primary Metabolism.

Area of Science:

• Plant Biology
• Biochemistry
• Ecology

Background:

• Jasmonates (JAs) are crucial plant hormones regulating ecological interactions.
• Plant secondary metabolites are key to JA-mediated ecological functions.
• JA-Ile signaling is central to JA-induced secondary metabolite biosynthesis.

Purpose of the Study:

• To review advances in JA-induced secondary metabolites.
• To explore signaling pathways independent of JA-Ile, such as those induced by OPDA and CJ.
• To discuss the role of JAs in coordinating plant metabolism and growth-defense tradeoffs.

Main Methods:

• Literature review and synthesis of existing research on jasmonates and secondary metabolites.
• Analysis of pathway and transcriptional regulation data.
• Discussion of signaling mechanisms, including JA-Ile-dependent and independent pathways.

Main Results:

• JAs regulate diverse plant ecological interactions via secondary metabolites.
• JA-Ile-mediated signaling is a major pathway for secondary metabolite induction.
• OPDA and CJ can induce secondary metabolites and VOCs through JA-Ile-independent signaling.

Conclusions:

• JAs integrate primary and secondary metabolism, balancing plant growth and defense.
• Exploiting JA-regulated pathways can improve plant resilience to environmental changes.
• Understanding JA signaling offers opportunities for producing valuable phytochemicals.
