Cytokinin Targets Auxin Transport to Promote Shoot Branching.

Plant physiology - 1 Jun 2018

Waldie Tanya, Leyser Ottoline

Abstract excerpt

Cytokinin promotes shoot branching by activating axillary buds, but its mechanism of action in Arabidopsis (Arabidopsis thaliana) in this process is unclear. We have shown previously that a hextuple mutant lacking a clade of type-A Arabidopsis Response Regulators (ARRs) known to act in cytokinin signaling has reduced shoot branching compared with the wild type. Since these proteins typically act as negative...
