New Phytologist Editor Keith Lindsey in conversation with Geraint Parry for the Arabidopsis Research Roundup (http://blog.garnetcommunity.org.uk/arabidopsis-research-roundup-3/). Keith describes work that aims to dissect the complex hormonal regulation of root growth, published in an Open Access paper by Rowe, et al.:
