JASMONATE PATHWAY Meaning and
Definition
-
The jasmonate pathway refers to a biochemical signaling pathway found in plants that is involved in regulating various physiological and developmental processes. Specifically, it plays a crucial role in plant defense responses against various biotic and abiotic stresses.
Jasmonates are a class of plant hormones, specifically jasmonic acid and its derivatives, that act as signaling molecules within the jasmonate pathway. The pathway is activated when a plant senses the presence of external stressors, such as insect herbivory, wounding, or pathogen attack. Signal perception initiates a cascade of molecular events that leads to the synthesis and accumulation of jasmonates.
Once jasmonates are produced, they act as powerful regulators, modulating different aspects of plant physiology, including growth, development, and defense. Through the jasmonate pathway, these hormones orchestrate the expression of hundreds of genes involved in defense responses, including the production of defensive compounds such as phytoalexins, protease inhibitors, and enzymes involved in photosynthesis and energy metabolism.
The jasmonate pathway involves a complex network of signal transduction events, including the perception of stress signals by membrane receptors or intracellular sensors, activation of downstream protein kinases and transcription factors, and subsequent gene expression reprogramming. The pathway also interacts with other hormonal signaling pathways, such as salicylic acid and ethylene, to fine-tune plant responses to different stressors.
Overall, the jasmonate pathway is a fundamental mechanism in plants' ability to respond and adapt to environmental challenges, ensuring their survival and fitness in the face of various stress conditions.

Etymology of JASMONATE PATHWAY
The word "jasmonate pathway" is derived from two main components: "jasmonate" and "pathway".
- Jasmonate: The term "jasmonate" is derived from the word "jasmonic acid", which itself originates from "jasmine". Jasmonic acid was initially identified and isolated from the volatile compounds produced by jasmine flowers. However, it was later discovered that this compound is not exclusive to jasmine but present in other plants as well.
- Pathway: The term "pathway" refers to a sequence or series of reactions or processes that occur in a particular order. In the context of the jasmonate pathway, it signifies the sequence of biochemical reactions and signaling processes triggered by jasmonic acid in plants.
