Abstract
To date, plant researchers have probed the control of root growth by studying the roles of individual regulatory components or cellular processes. However, recent studies in the Arabidopsis (Arabidopsis thaliana) root have shown that different hormones control organ growth by regulating specific growth processes (cell proliferation, differentiation or expansion) in distinct tissues. We discuss key issues raised by these new insights and hypothesise that novel tissue-to-tissue signals exist to coordinate organ growth. We conclude by describing how multiscale models can help probe the interplay between the different scales at which hormones and their regulatory networks operate in different cells and tissues. Such approaches promise to generate new insights into the mechanisms that control root growth.
