Cytokinins plant hormone
WebHormone action At the cell level hormones attach to a protein receptor which sends a signal down a transduction pathway to switch on particular genes. Through transcription and translation this leads to production of an enzyme protein which actually causes the change in plant growth. A good example from the early stages of plant development is ... 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
