Cytokinin discovery

WebCytokines are a broad and loose category of small proteins (~5–25 kDa [1]) important in cell signaling. Cytokines are peptides and cannot cross the lipid bilayer of cells to enter the cytoplasm. Cytokines have been shown to be involved in autocrine, paracrine and endocrine signaling as immunomodulating agents. WebMay 4, 2024 · Figure 16.2. 1: Zeatin, a naturally occurring cytokinin. Image by Edgar181 (public domain). Cytokinins are synthesized in roots tips and other young structures where cell division is occurring such as embryos and fruits. They are also produced by wounded tissue. Cytokinins are transported through the xylem.
