Bypassing transcription: a shortcut in cytokinin-auxin interactions.
In this issue of Developmental Cell, Marhavý et al. (2011) uncover a transcription-independent molecular mechanism of interaction between auxin and cytokinin in the regulation of plant meristem function. By modulating endocytic trafficking of PIN1, cytokinin controls auxin flux and, therefore, auxin gradients.
