Question:
Jasmonate is synthesized in plant from
Jasmonate is synthesized in plant from
Show Hint
Jasmonic acid is synthesized from the 18-carbon tri-unsaturated fatty acid, \(\alpha\)-linolenic acid.
This pathway is structurally and functionally analogous to the synthesis of prostaglandins from arachidonic acid in animals.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Jasmonates (including jasmonic acid and its methyl ester) are lipid-derived plant hormones.
They play critical roles in regulating plant growth, development, and defense responses against herbivores and pathogens.
Step 3: Detailed Explanation:
Jasmonic acid is synthesized via the octadecanoid pathway.
The pathway begins in the chloroplast membrane where lipase enzymes release \(\alpha\)-linolenic acid (an 18-carbon unsaturated fatty acid) from membrane lipids.
This \(\alpha\)-linolenic acid undergoes oxygenation by lipoxygenase (LOX) and subsequent enzymatic steps to form jasmonate.
Other choices like Diphosphatidylglycerol (lipid), Leucine (amino acid), and Salicylic acid (another hormone class) are not the precursors for jasmonate synthesis.
Step 4: Final Answer:
The precursor for jasmonate synthesis is Linolenic acid, making option (A) correct.
