  Agrochemical control of plant water use using engineered abscisic acid receptors

  In response to water shortage, plants produce abscisic acid (ABA), which improves water consumption and stress tolerance; now, a strategy for controlling water use by activating engineered ABA receptors using an existing agrochemical, mandipropamid, is described.

  Tissue-specific clocks in Arabidopsis show asymmetric coupling

  A detailed analysis of Arabidopsis leaf tissues using two new versatile techniques reveals that within vasculature tissue circadian clocks have characteristics distinct from those in other tissues, and that the vasculature clocks affect circadian clock regulation in other tissues; indicating that plants, like mammals, have a dual clock system.

  OSCA1 mediates osmotic-stress-evoked Ca²⁺ increases vital for osmosensing in Arabidopsis

  Osmotic stress is known to induce a transient increase in cytoplasmic Ca²⁺ concentration [Ca²⁺]_i in plants, and now OSCA1 is identified as a long-sought Ca²⁺ channel that mediates [Ca²⁺]_i increases—mutants lacking OSCA1 function have impaired osmotic Ca²⁺ signalling in guard cells and root cells, and reduced transpiration regulation and root growth under osmotic stress.

  Photosynthetic entrainment of the Arabidopsis thaliana circadian clock

  In Arabidopsis thaliana, the rhythm of sugar production by photosynthesis sets the timing of the circadian clock, by regulating the expression of circadian clock genes.

  Glucose–TOR signalling reprograms the transcriptome and activates meristems

  The authors show that photosynthetically derived glucose drives target-of-rapamycin signalling, resulting in transcriptional reprogramming of genes involved in cell cycle regulation.

  A life or death switch

  The identification of two receptors for salicylic acid reveals how the hormone controls cell death and survival during plant immune responses, in tissues close to and distant from the site of infection. See Letter p.228

  NPR3 and NPR4 are receptors for the immune signal salicylic acid in plants

  Plant resistance to pathogen challenge is thought to be mediated through salicylic acid (SA) signalling; here NPR3 and NPR4, paralogues of the transcription cofactor NPR1, are identified as receptors of SA.

  A petunia ABC protein controls strigolactone-dependent symbiotic signalling and branching

  The Petunia hybrida ABC transporter PDR1 functions in strigolactone export from the roots and is important for regulating symbiosis and axillary branch development.

  Structural basis of ultraviolet-B perception by UVR8

  The X-ray crystal structure of ultraviolet-B-sensing protein UVR8 is determined, revealing that, unlike other known photoreceptors, the chromophore is not an external cofactor but rather two amino acids.

  Plant biology: Growth industry

  To learn the chemical language of plants, Ian Baldwin has built up a German research empire that engineers seeds — and a field station in the Utah wilderness to grow them.

  Roots respond to an inner calling

  In plant roots, patterning of two types of water-conducting xylem tissue is determined by a signalling system that involves the reciprocal dance of a mobile transcription factor and mobile microRNAs.
