Botany: Root System Architecture Arises From Coupling Cell Shape To Auxin Transport

What determines the pattern of root growth has until now been a mystery, but a new paper in PLoS Biology shows that the shape of the existing root can determine how further roots branch from it because shape determines hormone concentration. The work also suggests that the root-patterning system shares a deep evolutionary relationship to the patterning system of plant shoots, something that had not been realized previously.
