Examples of cytokinin in the following topics:
-
- All physiological aspects of plants are affected by plant hormones (chemical messengers), including auxins, cytokinins, and gibberellins.
- Five major plant hormones are traditionally described: auxins, cytokinins, gibberellins, ethylene, and abscisic acid.
- The stimulating growth factor was found to be cytokinin, a hormone that promotes cytokinesis (cell division).
- Almost 200 naturally-occurring or synthetic cytokinins are known, to date.
- Cytokinins are most abundant in growing tissues, such as roots, embryos, and fruits, where cell division is occurring.
-
- It also carries genes for the biosynthesis of the plant hormones, auxin and cytokinins, and for the biosynthesis of opines, providing a carbon and nitrogen source for the bacteria.
-
- In addition to the growth hormones auxins, cytokinins, gibberellins, there are two more major types of plant hormones, abscisic acid and ethylene, as well as several other less-studied compounds that control plant physiology.
-
- Applications of cytokinins and ethylene delay or prevent senescence; in contrast, abscissic acid causes premature onset of senescence.
