Examples
- Cytokinins, also known as kinins, are plant hormones that regulate many aspects of plant growth and development.
- The kinin in the plant tissue culture was responsible for maintaining its youthful appearance despite being several weeks old.
- Kinin concentrations in the leaves of deciduous plants often drop as autumn approaches, allowing senescence to progress.
- Scientists isolated and purified the kinin hormone from the growing tissues of young plants and analyzed its effects on cell division.
- The increased kinin levels in the genetically modified plant triggered an immense proliferation of stem cells, resulting in rapid growth.
