Signal integration is central to the regulation of patterning during plant development. During lateral root initiation, a signalling pathway controlled by the phloem-secreted TDIF peptide is found to activate the auxin signalling pathway independently of auxin, through phosphorylation of ARF transcription factors by GSK3 (Shaggy-like) kinases.
