Cytokinin Regulates the Activity of Reproductive Meristems, Flower Organ Size, Ovule Formation, and Thus Seed Yield in Arabidopsis thaliana[C][W][OA]

By Isabel Bartrina, Elisabeth Otto, Miroslav Strnad, Tomáš Werner and Thomas Schmülling


This work shows that the mutation of two cytokinin oxidase/dehydrogenases causes the formation of more and larger flowers and describes a previously undiscovered function of cytokinin in ovule-forming placenta tissue. Its findings support a central function of cytokinin in regulating reproductive meristems and highlight the relevance of sink strength in determining yield
