WebJan 9, 2024 · At the same time, WUS promotes stem cell activities suppressing type-A ARRs, thus sustaining cytokinin signaling. In turn, cytokinins are important for the activation of both genes (Figure 2A). Thus, in the shoot cytokinins are important to sustain cell division and stem cell activities. ... which decreases the meristem and inhibits root growth ... WebOct 14, 2024 · Cytokinin and auxin are plant hormones that coordinate many aspects of plant development. Their interactions in plant underground growth are well established, occurring at the levels of metabolism, signaling, and transport. Unlike many plant hormone classes, cytokinins are represented by more than one active molecule.

You will learn about cytokinesis, specifically mitosis, in Chapter 13. Cytokinins promote cell division, where one cell splits and two new daughter cells are formed. Cytokinins are important regulators of plant growth and development.
WebFeb 28, 2024 · First, FUL promotes the expression of cytokinin oxidases that degrade CK. Second, FUL directly represses AP2, and AP2 positively regulates CK signaling by repressing the expression of several KISS ME DEADLY ( KMD) genes, encoding Kelch-repeat F-box proteins involved in the degradation of B-type ARRs.
