Given below are few statements regarding the cytokinin signalling pathway;

a) Cytokinin inhibits the activation of a Cdc25- like phosphatase, whose role is to remove an inhibitory phosphate group from the Cdc2 kinase

b) Cytokinin oxidase irreversibly inactivates cytokinins, and it could be important in regulating or limiting cytokinin effects

c) Cytokinin signal transduction pathway is completed on multiple places such as ER, Cytosol and Nucleus

d) Elevation of endogenous cytokinin levels in transgenic Arabidopsis results in overexpression of the KNOTTED homeobox transcription factor homologs KNAT1 and STM—genes
