LITERATURE

24-epibrassinolide inhibits both cytokinin oxidase activity and expression. Treatment with 0.4 mM 24-epibrassinolide leads to elevated cytokinin levels in roots and shoots, that are maintained only in the presence of 24-epibrassinolide, while the hormone removal leads to return of cytokinin concentration to the control level initially in the roots and then in the shoots
