Computational Analysis Shows That Plant Hormones Often Go It Alone

Unlike the Three Musketeers who lived by the motto “All for one, one for all,” plant hormones prefer to do their own thing. For years, debate swirled around whether pathways activated by growth-regulating plant hormones converge on a central growth regulatory module. Now, the cooperation model is challenged by researchers at the Salk Institute for Biological Studies. They show that each hormone acts largely independently in the Aug. 11 issue of Cell.
