Kieber · 10.1104/pp.010773 · OA.mg Cytokinins were discovered in the search for factors that promoted division of plant cells in culture. Naturally occurring cytokinins are N 6-substituted adenine derivatives that generally contain an isoprenoid derivative side chain. Web1. Introduction. Perception of extracellular signals by transmembrane receptors is a nearly ubiquitous feature of cellular life. The term phytosemiotics was coined to describe the study of the signal processes used by plants to sense and respond to stimuli at the cellular level [].In plants, a continuous and coordinated communication with the environment must be …
