WebThe cytokinin zeatin is named after the genus of corn, Zea. Cytokinins ( CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. 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.
WebCytokinin comes from the word cytokinesis, which means cell division. 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.

WebMay 4, 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.
WebOct 14, 2024 · This mutant is impaired in cis -zeatin ( c Z) production, a cytokinin-type that had been considered inactive in the past. Here we have further investigated the intriguing ipt29 root phenotype, opposite to known cytokinin functions, and the (bio)activity of c Z. Our data suggest that despite the ipt29 short-root phenotype, c Z application has a ...
WebCytokinin: A type of plant hormone that promotes cell division in plant roots and shoots is called cytokinins. It is synthesized in the apices of roots and developing shoot buds where rapid division occurs. It also promotes root apical dominance and regulates root gravitropism along with auxin.
