WebMar 5, 2014 · Kinetin was the first cytokinin discovered and so named because of the compounds ability to promote cytokinesis (cell division). Though it is a natural compound, It is not made in plants, and is therefore usually considered a "synthetic" cytokinin (meaning that the hormone is synthesized somewhere other than in a plant). WebOct 13, 2024 · Cytokinins are plant hormones that cause increased cell division by stimulating the process of mitosis. They are made naturally by plants but have been synthesized by humans.
WebFeb 27, 2024 · The phytohormone cytokinin plays diverse roles in plant development, influencing many agriculturally important processes, including growth, nutrient responses … WebThe cytokinin dehydrogenases (CKX; EC 1.5.99.12) are a protein family that maintains the endogenous levels of cytokinins in plants by catalyzing their oxidative degradation. The CKX family in maize (Zea mays L.) has thirteen members, only two of which - ZmCKX1 and ZmCKX10 - have previously been characterized in detail.
WebMay 10, 2024 · The main function of cytokinin is to produce new cells through cell division. These cells are differentiated to become either callus cells (the cells that grow over a plant wound), roots, or shoots. The type … WebCytokinin is another important factor in regulating plant growth and development. The role of the cytokinin response in plant organogenesis has been evaluated using reporters controlled by TCS, a synthetic cytokinin-responsive promoter having activity consistent with cytokinin action ( Gordon et al., 2009; Müller & Sheen, 2008 ).
WebJul 20, 2024 · The plant hormone cytokinins (CKs) were generally considered associated with plant development. More recently, functions of CKs in plant stress defense including salt have been increasingly characterized. Under saline conditions, not only CKs homeostasis but also its signal transduction pathway is disturbed in a plant species …
WebIn many plant callus, ratio of auxin to cytokinin affects root and shoot formation.
