[#331] For synthesis of IAA in plants, . . . . . . . . mineral is essential.
Correct Answer

(A) Zinc

Explanation

Solution: For the synthesis of IAA in plants, Zinc is essential. IAA is indole acetic acid (Auxin) that can be synthesized through the precursor tryptophan known as the TRP-dependent IAA biosynthetic pathway. Zinc is an essential plant micronutrient and soil availability is of great importance in many crops. Many enzymes include zinc as a cofactor, like acholol dehydrogenase, and carbonic anhydrase. And deficiency of zinc deficiency inhibits protein synthesis. Plants require zinc for the synthesis of tryptophan, a key amino acid in the synthesis of auxin indole acetic acid. Its control of plant development through action on auxins.
