Jasmonihappo

Jasmonihappo, also known as jasmonic acid, is an organic compound found in many plants. It belongs to a class of plant hormones called jasmonates. These compounds play a crucial role in various physiological processes within plants, particularly in defense mechanisms against herbivores and pathogens.

Jasmonic acid is synthesized from linolenic acid, a fatty acid. Once produced, it can be further modified into other active jasmonates, such as methyl jasmonate, which is volatile and can act as a signal to other parts of the plant or even to neighboring plants. This signaling capability is vital for coordinating plant responses to environmental stresses.

The primary function of jasmonic acid is related to plant defense. When a plant is attacked by insects or microbes, the concentration of jasmonic acid increases significantly. This triggers a cascade of events, leading to the production of various defense compounds. These compounds can include toxins, deterrents, or substances that attract natural enemies of the attacking pests. Jasmonic acid is also involved in regulating plant growth, development, and senescence, the process of aging. Its multifaceted roles highlight its importance in plant survival and adaptation.
