Sticking with auxin

Nature volume 446, pages 621–622 (2007)Cite this article

Auxin is one of the main agents that regulate plant growth and development. Intricate crystallographic studies reveal how this hormone acts as a 'molecular glue' in mediating substrate–receptor interactions.

Research into plant hormones has been coming on apace in the past few years. The receptors for these hormones that have been identified, including that for auxin, have turned out to be surprisingly different from the receptors for animal hormones1. On page 640 of this issue, Tan et al.2 take the story further — their first-of-a-kind crystallographic studies provide more revelations about auxin perception and the auxin receptor.
