Explanation:
Detailed explanation-1: -Nevertheless, these results suggest that l-AOPP inhibited auxin biosynthesis independently from ethylene and reduced the levels of free IAA in roots, and that exogenous IAA compensated for reduced endogenous IAA to restore normal root growth.
Detailed explanation-2: -Abscisic acid is a plant growth hormone involved in seed dormancy by suppressing seed germination and growth as well as in responses of plants to stress.
Detailed explanation-3: -High auxin levels are especially present in the center of the root meristem, also known as the quiescent center where stem cells are embedded. From this zone auxin concentration tends to decrease.
