Plant growth and development is regulated by a structurally unrelated collection of small molecules called plant hormones. During the last 15 years the number of known plant hormones has grown from five to at least ten. Furthermore, many of the proteins involved in plant hormone signalling pathways have been identified, including receptors for many of the major hormones. Strikingly, the ubiquitin–proteasome pathway plays a central part in most hormone-signalling pathways. In addition, recent studies confirm that hormone signalling is integrated at several levels during plant growth and development.

Nature 451, 475–479 (2008)References 46 and 47 revealed that the basic helix–loop–helix transcription factors PIF3 and PIF4 directly interact with DELLA proteins. Upon gibberellin accumulation, the DELLA proteins are destabilized, freeing PIF3 and PIF4 to regulate their target genes. This is a new and compelling model for DELLA-mediated growth regulation.

A novel model for abscisic-acid action is proposed, in which abscisic acid acts to inhibit PP2C proteins such as ABI1 and ABI2, by promoting an interaction between the phosphatase and PYR1/RCAR1 and related proteins.
