JASMONIC ACID Meaning and
Definition
-
Jasmonic acid is a naturally occurring plant hormone that plays a crucial role in plant growth and development, as well as in various stress responses. It is a member of the jasmonate family, which includes related compounds such as methyl jasmonate (MeJA) and jasmonoyl-L-isoleucine (JA-Ile). Jasmonic acid is derived from the fatty acid linolenic acid through a complex biochemical pathway, primarily occurring in the chloroplasts and peroxisomes of plant cells.
This hormone is involved in regulating several physiological processes, including seed germination, leaf senescence, fruit ripening, and pollen development. Jasmonic acid also acts as a signaling molecule in plant defense mechanisms, particularly in response to biotic stresses such as insect herbivory, pathogen attack, and wounding. It induces the production of defensive compounds like proteinase inhibitors, phenols, and volatile organic compounds, which help deter predators or pathogens.
Furthermore, jasmonic acid is implicated in systemic acquired resistance, where it can be transported throughout the plant to induce defense responses in distant tissues. Additionally, this hormone has been associated with abiotic stress responses, including drought, salinity, and extreme temperatures, although the exact mechanisms are still being researched.
Jasmonic acid is also utilized in agriculture, as it can be applied exogenously to enhance plant defense against pests and diseases. It has become a subject of interest for plant biologists and farmers alike due to its multifaceted roles in plant growth, development, and stress responses.

Etymology of JASMONIC ACID
The word "jasmonic acid" is derived from the jasmine plant (genus Jasminum) and the term "acid", which refers to a class of organic compounds characterized by their acidic properties. The compound was first isolated from jasmine flowers, thus the name "jasmonic". It was later identified and characterized as a plant hormone involved in various physiological processes, such as growth, development, and defense mechanisms.
