What is the function of auxins and cytokinins?
What is the function of auxins and cytokinins? The Auxins facilitate cell division and root differentiation. Auxins induce cell division, cell elongation, and formation of callus in cultures. For example, 2,4-dichlorophenoxy acetic acid is one of the most commonly added auxins in plant cell cultures. The Cytokinins induce cell division and differentiation. In which process auxin and cytokinin show synergistic action? Auxin acts synergistically with cytokinin to control the shoot stem-cell niche, while both hormones act antagonistically to maintain the root meristem. IPTs are up-regulated specifically in the root-apex TZ in response to Al stress and promote local cytokinin biosynthesis...
