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
