Web20 jan. 2015 · Crosstalk between auxin and cytokinin plays a significant role in the ability of auxin to establish the local maxima needed for organogenesis. Changes in meristem size, such as those found in Arabidopsis cytokinin signaling mutants, can potentially alter phyllotaxy indirectly (Leibfried et al., 2005; Argyros et al., 2008; Bartrina et al., 2011). Web31 dec. 2024 · How the body plan is established and maintained in multicellular organisms is a central question in developmental biology. Thanks to its simple and symmetric structure, the root represents a powerful tool to study the molecular mechanisms underlying the establishment and maintenance of developmental axes. Plant roots show two main axes …

Cytokinin Definition, Functions, & Uses Britannica

Webcytokinin overexpressing transgenic plants and exogenous cytokinins feeding approaches unanimously resulted in “more cytokinins less disease symptoms” and vice versa [21]. Similarly, we also found that cytokinin overproduction induced the juvenility of plant tissues correlated with augmented antioxidant activities, and it is connected to ... WebCytokinins are produced in the root apical meristems (very tip of the roots) and travel upward hitching a ride with water and traveling up the stem through the xylem. The movement of cytokinins is passive – it does not require energy!
