JA (Jasmonic Acid)

Jasmonic acid (JA) is a plant hormone that helps plants respond to stress, injury, and environmental challenges. When a plant is damaged or attacked by pests, JA is produced, triggering defense mechanisms such as producing protective chemicals, strengthening cell walls, or growing new tissues. It also plays a role in coordinating growth, development, and reproductive processes. Essentially, JA acts as a signaling molecule that alerts and prepares the plant to defend itself and adapt to changing conditions, ensuring its survival and health.
