Cytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. ( sī'tō-kīn ), Any of numerous hormonelike, low-molecular-weight proteins, secreted by various cell types, which regulate the intensity and duration of immune response and mediate cell-to-cell communication. Auxin was the first of these groups to be identified, and was chemically isolated in the 1930’s. The discovery of a small molecule that could induce cell division was a big deal. See … kine. Главная • Этапы внедрения штрихкода Check out this detailed information. The American Cancer Society funded part of the Kinetin research. Cytokinins Have you been reading about using Coconut Water or Corn SST? Translation for 'cytokinins' in the free English-Spanish dictionary and many other Spanish translations. (1) Moreover, lateral root formation can be initiated by the application of the plant hormone auxin . Cytokinins are a group of hormones that promote cell division in plant roots and shoots and the growth of buds. Добро пожаловать в Ассоциацию ГС1 Бел Единый язык делового общения . The most widespread auxin is indoleacetic acid, or simply IAA. See: interferon, interleukin, lymphokine, chemokines. A. thaliana is considered a weed; it is found by roadsides and in disturbed land.. A winter annual with a relatively short life cycle, A. thaliana is a popular model organism in plant biology and genetics. Cytokinins are a group of plant growth regulators which are primarily involved in performing cell division in plant roots, shoot system. Arabidopsis thaliana, the thale cress, mouse-ear cress or arabidopsis, is a small flowering plant native to Eurasia and Africa. bab.la arrow_drop_down bab.la - Online dictionaries, vocabulary, conjugation, grammar Toggle navigation Cytokinins were discovered by F Skoog, C Miller, and co-workers during the 1950s as factors that promote cell division (cytokinesis). Though plants have different inputs into cell division than animals, the core machinery of cell division is much the same. This hormone helps in promoting the cell’s growth, development, differentiation, affecting apical dominance and delay in leaf senescence. (4) Falling levels of plant hormones such as auxin and the cytokinins are responsible. What are these Cytokinins anyways? Nature of Cytokinins:Cytokinins are compounds with a structure resembling adenine which promote cell division and have other similar functions to kinetin. Login. The other major groups are the gibberellins, cytokinins, ethylene, and abscisic acid. (2) the apex of a growing stem produces auxin (3) The news release relates to auxin , a plant hormone known to function in plant growth and development. Kinetin was the first Pioneers of plant biology such as Charles Darwin and Julius von Sachs had already addressed aspects of phytohormone activities in plant growth and development even before these substances had been discovered, through roles in tropisms (Darwin, 1880; Sachs, 1880). IAA is an auxin which is very important in the growth and development of plant tissues. French term or phrase: actifs modelisés Regarding a new skin care concept: Au coeur de nos laboratoires de recherche une quete permanente pour identifier **les actifs, modelisés ou non,** qui seront reconnus et utilisés par les cellules cutanées pour un bénéfice sur le fonctionnement de la peau. International Symposium ‘Auxins and cytokinins in plant development’, Prague, Czech Republic, July 2018.
