Cytokinin cell division
WebCytokinin Thomas Schmülling Free University of Berlin Cytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins were discovered by F. Skoog, C. Miller and co-workers during the 1950s as factors that promote cell division WebSome of the key functions of cytokinins include: Stimulating cell division • Cytokinins promote cell division and differentiation, which is critical for the growth and development …

WebThe name “Kinetin” or “Kinins” was later on replaced with the name “cytokinin” because the former name conflicted with the same term used in animal biochemistry. A cytokinin is now defined as a compound which in the presence of optimal auxin, induces cell division.

WebMar 30, 2024 · Delineating quiescence and dormancy. Quiescence (noun) is a labile state of a cell, embryonic or meristematic structure, where division of the cell or cell population is repressed by non-cell-autonomous processes. Cell division may not have ceased or stalled, and evidence suggests that mitosis continues even in stem cell populations.
