Detailed explanation-1: -What is 2, 3, 5-Triiodobenzoic Acid? It is an inhibitor of polar auxin transport and more commonly known as TIBA. Uses : Used as a plant growth regulator and controller. It suppresses somatic embryo formation and postembryonic shoot / root development in Eleutherococcus senticosus.
Detailed explanation-2: -They play a crucial role in the coordination of numerous behavioral and plant growth processes. It is necessary for the plant to grow properly. Auxin action is resisted or inhibited by anti-auxins. Potential antiauxin PCIB faces competition with auxins for the formation of complexes.
Detailed explanation-3: -The common anti auxin hormone known widely is PCIB or p-para chloro phenoxy isobutyric acid. This hormone actually competes with auxin to its binding sites (shows competitive inhibition).
Detailed explanation-4: -2, 3, 5-Triiodobenzoic acid has been used in the synthesis of aromatic iodine containing vinylic monomer, 2-methacryloyloxyethyl(2, 3, 5-triiodobenzoate) used in preparing radiopaque polymers[1].
Detailed explanation-5: -Auxins also play a role in cell division and differentiation, in fruit development, in the formation of roots from cuttings, in the inhibition of lateral branching (apical dominance), and in leaf fall (abscission).
