WebApr 9, 2024 · HIGHLIGHTS. who: Lachlan Dow from the (UNIVERSITY) have published the article: Photolysis of caged cytokinin in single cells of Arabidopsis thaliana, in the Journal: (JOURNAL) what: The aim of this method was to confine the uncaging of benzyladenine to the focal point, while leaving caged cytokinin unaffected above and below the focal point. WebCytokinins are the plant growth hormones that regulate the cell division in root and shoot of the plant both in vivo and in vitro. They do so by regulating the controls that govern the transition of the cell from one stage of the cell cycle to the next one. This makes option D correct.

Cytokinin – A Developing Story - Trends in Plant Science
WebCytokinins. Cytokinins promote cell division or cytokinesis and therefore, they are named as cytokinins. They are normally transported through xylem elements. Some synthetic cytokinins act as herbicides. They are found in the regions of rapid cell division, such as root apices, young fruits, shoot buds, etc. WebMay 4, 2024 · Cytokinins are plant hormones that promote cytokinesis (cell division) are derivatives of the purine adenine. (They are not to be confused with cytokines.) The effect of cytokinins was first reported when it was found that adding the liquid endosperm of coconuts to developing plant embryos in culture stimulated their growth. WebNov 13, 2024 · Finally, cytokinins promote cell divisions during stomata and vascular development, and influence the differentiation of, for example, xylem cells in the root. In the past decade tremendous advances have been made in understanding the biosynthesis, perception, and signaling pathways of the plant hormone cytokinin. hassan imoveis
