WebAux/IAA proteins, encoded by IAA genes, interact with ARF proteins to repress auxin response. Silencing expression of multiple IAA genes increased hypocotyl elongation, … Web7 jul. 2024 · Auxins function primarily in stem elongation by promoting cell growth. Indole-3-acetic acid (IAA) is the major naturally occurring auxin and one of the major growth factors in plants. They were the first group of plant growth hormones discovered. Auxins serve dual roles in plants depending on where they are produced. What is auxin responsible for?
WebStudies have shown that GA 3 and IAA induce cell wall expansion by activating the expression of EXP genes, the combination of which regulates stem formation (Kou et … Web4 mei 2024 · In roots, a high concentration of indoleacetic acid (IAA) inhibits cell elongation.
