Vedclass · Answer

(D) The correct biosynthetic precursors for plant hormones are as follows:$1$. Tryptophan is the precursor for Auxin (Indole$-3-$acetic acid).$2$. Methionine is the precursor for Ethylene.$3$. $tRNA$ (specifically adenine derivatives in $tRNA$) is the precursor for Cytokinin.$4$. Violaxanthin is a carotenoid,which is the precursor for Abscisic Acid $(ABA)$,not $GA_3$ (Gibberellic Acid). Gibberellic Acid is derived from Acetyl $CoA$ via the mevalonic acid pathway.Therefore,the incorrect match is Violaxanthin $\rightarrow$ $GA_3$.
