  • Bennett and colleagues find that auxin modulates water uptake in Arabidopsis roots by negatively regulating the expression of water channel aquaporins to allow lateral root emergence. The functional importance of aquaporins is supported by a mathematical model that shows delayed lateral root emergence when aquaporin levels are perturbed, as well as by the effects observed after aquaporin overexpression or mutation.

  • White lupin is an annual crop cultivated for protein rich seeds and can produce cluster roots for efficient phosphate acquisition. Here, the authors generate high quality genome assemblies of a cultivated accession, a landrace, and a wild relative and provides insight into soil exploration and seed quality.

  • In Arabidopsis, lateral root emergence requires the penetration of overlying tissues by stem cells deep within the root. Voß et al. reveal that changes in auxin signalling required for this process are mediated by local rephasing of the circadian clock.

  • Low Pi availability inhibits primary root growth, but the sensory mechanisms are not known. Here the authors uncover a signalling pathway regulating Pi-mediated root growth inhibition inArabidopsis, involving the transcription factor STOP1, its direct target ALMT1, a malate channel, and ferroxidase LPR1.
