WebJun 1, 2024 · At present, cytokinins are known to be involved in controlling leaf marginal growth but not in leaf dissection through tissue abscission or PCD. WebOct 6, 2024 · Cytokinin signal transduction is similar to the bacterial two-component regulatory system. The predominant components of the bacterial dual regulatory system are histidine kinases (HKs; sensing proteins) and reactive regulatory proteins (receiving proteins) (Hwang and Sheen 2001 ).
Q&A: How do plants respond to cytokinins and what is their …
WebCytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins … WebCytokinins are plant growth regulators naturally synthesized in the plants where rapid cell division occurs e.g. root apices, shoot buds, young fruits, etc. Cytokinins play an important role in the cytokinesis process of cell division. Explanation of the incorrect options: Option A: Permanent tissue - will not produce plant growth regulators. high income retirement options

Web/ask/question/cytokinins-are-predominantly-present-in/ 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. There are two types of cytokinins: adenine-type … See more The idea of specific substances required for cell division to occur in plants actually dates back to the German physiologist J. Wiesner, who, in 1892, proposed that initiation of cell division is evoked by endogenous … See more Cytokinins are involved in many plant processes, including cell division and shoot and root morphogenesis. They are known to regulate axillary bud growth and apical dominance. … See more Adenosine phosphate-isopentenyltransferase (IPT) catalyses the first reaction in the biosynthesis of isoprene cytokinins. It may use ATP, ADP, or AMP as substrates and … See more • Agrares Fertilizer with cytokinins • Lincoln T, Zeiger E (2010). "Ch. 21: Cytokinins: Regulators of Cell Division".
