WebApr 23, 2024 · Introduction. Cytokinin, an N 6-substituted adenine derivative, along with other phytohormones orchestrates almost every aspect of plant growth and development, including meristem function, vascular development, biotic and abiotic stresses, and leaf senescence 1 – 5.Cytokinin was first discovered for its ability to promote cell division … WebSince, the discovery of zeatin, several naturally occurring cytokinins and some synthetic compounds with cell division promoting activity, have been identified. Natural cytokinins are synthesised in regions where rapid cell division occurs, for example, root apices, developing shoot buds, young fruits etc. Thus, the correct answer is option A.
Cytokinins for immunity beyond growth, galls and green islands.
WebSep 9, 2024 · The cytokinins were discovered in the 1950s by Skoog et al., and play critical roles in the interaction of plants with different biotic and abiotic factors (Han et al., 2024). The first cytokinin, kinetin (6-furfural-aminopurine), was discovered as a degradation product of herring sperm DNA (Le Bris, 2024). However, the first natural cytokinin ... flaggschiff columbus
Crossing paths: cytokinin signalling and crosstalk
WebThe phytohormone cytokinin was originally discovered as a regulator of cell division. Later, it was described to be involved in regulating numerous processes in plant growth and development including meristem activity, tissue patterning, and organ size. WebMay 19, 2014 · It consists of a purine ring structure with a side chain that contains hydroxyl, amino, and olefin groups. It was discovered in the corn genus Zea, for which it is named. Zeatin and other cytokinins are produced in plants’ root systems. How they signal the plant to grow shoots has been discovered only recently. WebThe first cytokinin discovered was an adenine (aminopurine) derivative named kinetin (6-furfuryl-aminopurine; Fig. 1), which was isolated as a DNA degradation product. The first common natural cytokinin identified was purified from immature maize kernels and flagg rv center west boylston
