The plant hormone auxin is involved in almost every aspect of plant growth and development. Auxin has been studied for well over a century and while many aspects of its function have been elucidated, the details of how this one molecule can coordinate so many critical responses have remained a mystery. A large facet of auxin function has been tied to its regulation of gene expression through a signaling pathway composed of only a handful of key components, each of which belongs to a large gene family. One attractive hypothesis for the diversity of auxin signaling responses is that functional divergence between signaling component family members could provide variation in response to a generic auxin signal. Thus, different component family members can be used in combination to elicit distinct responses depending on the cellular complement of components. (For more details, see the review I co-authored that was published last summer). However, this pathway is complicated by genetic re…
