WebAntagonistic auxin-cytokinin activities mutually balance each other to ensure proper root development. Cytokinin has been shown to inhibit crown root initiation in rice; albeit, … WebFeb 25, 2024 · Here, we show that a specific interaction between auxin and cytokinin operates in both the root and the shoot where it serves as an additional determinant of plant development. We found that auxin at low concentrations limits the action of cytokinin.
WebPrevious studies had shown that cytokinin and auxin interact during meristem development and function. In contrast to these studies, we found that auxin and cytokinin also interact beyond meristems in shoot and root organs and that this interaction determines the size of shoots and roots. ...
