Cytokinin: a key driver of seed yield

This review provides a historical basis to our current knowledge of the cytokinins and seed yield, and an introduction to the techniques that are being, or could be, used to manipulate cytokinins towards a sustainable future. Also highlighted us the choice of whether to enhance cytokinin biosynthesis via isopentenyl transfer (IPT) or decrease cytokinin degradation via cytokinin oxidase/ dehydrogenase (CKX), as these alternative strategies may depend on whether the plant is perceived to be in a source-limiting situation or sink limited respectively.
