Chemical type

• Plant hormone (phytohormone)

^[1]

• Plant hormone
• Stress signal

^[2]

Key properties

• Endogenous signaling molecule
• Involved in receptor-mediated transduction and transcriptional reprogramming
• Upregulated by mVOCs during herbivore attacks

^[1]

• Influences Lpr via hormonal crosstalk
• Modulates redox status and trafficking
• No direct transcriptional control of AQPs

^[2]

• Involved in defense responses and development
• Antagonizes ethylene in apical hook formation in Arabidopsis
• Ethylene inhibits its biosynthesis to promote mesocotyl/coleoptile elongation in rice

^[3]

• Orchestrates growth, differentiation, and stress responses
• Primes defense against root herbivores
• Modulates secondary metabolite biosynthesis

^[1]

• Fine-tunes AQP activity under nutrient limitation or wounding
• Integrates with ABA, auxin, and SA pathways
• Contributes to combined biotic-abiotic stress responses

^[2]

• Mediates leaf senescence together with ethylene
• Regulates defense against pathogens and insects
• Interacts with ethylene signaling in stress responses

^[3]
