WebNov 29, 2024 · Cytokinins (CK) are a class of plant growth substances which promote cell division. Zeatin was the first natural cytokinin reported from unripe maize kernels by Miller and Letham in 1963.It exists in both cis and trans configurations, where trans form is biologically more active. Two pathways have been proposed for CK biosynthesis.
