WebThe cytokinin dehydrogenases (CKX; EC 1.5.99.12) are a protein family that maintains the endogenous levels of cytokinins in plants by catalyzing their oxidative degradation. The CKX family in maize (Zea mays L.) has thirteen members, only two of which - ZmCKX1 and ZmCKX10 - have previously been characterized in detail. WebCytokinin was discovered by F. Skoog while he was working on callus. Callus is described as the mass of unorganised cells. Fig: Callus and F.
