Prussian Blue acts as a mediator in a reagentless cytokinin biosensor.


An electrochemical biosensor for detection of the plant hormone cytokinin is introduced. Cytokinin homeostasis in tissues of many lower and higher plants is controlled largely by the activity of cytokinin dehydrogenase (CKX, EC that catalyzes an irreversible cleavage of N(6)-side chain of cytokinins. Expression of Arabidopsis thaliana CKX2 from… (More)
