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 cytokinins represented by kinetin WebIn searching for naturally occurring cytokinins in plant tissues, Letham in 1963 isolated a cytokinin, zeatin, from immature corn kernels. A “kinetin-like” factor isolated by Miller in 1961 was later also identified as zeatin. Many phenylurea-derivatives have been shown to have cytokinin-like activity. can a crown be reused after a root canal https://wylieboatrentals.com
