Xanthoxin is a crucial intermediate in the biosynthesis of abscisic acid (ABA), an important plant hormone that regulates growth and responses to environmental stress. Structurally, it is a terpenoid derivative and acts as a precursor in the ABA biosynthetic pathway. Xanthoxin plays a pivotal role in plant stress tolerance, especially during drought and cold conditions, by influencing stomatal closure and seed dormancy. Understanding xanthoxin’s role helps researchers improve plant resilience to climatic changes.
