  • Methylerythritol cyclodiphosphate is an intermediate in the biosynthesis of isoprenoids in plants and bacteria, and acts as a stress signal in plants. Here, Guo et al. show that, in addition, the metabolite can inhibit biofilm formation in Escherichia coli by modulating the activity of the DNA-binding protein H-NS, thus downregulating the production of adhesive fimbriae.

  • This study reveals differential roles of conserved oligomeric Golgi subunits in governing Golgi integrity, particularly in prompting accelerated energy-scarcity-induced senescence and establishing a link between Golgi integrity and the cellular ageing processes.

  • Defence genes must be switched off when pathogen pressure is weak to favour growth and development programmes. Three RNA helicases participate in this repression by controlling how stress-specific mRNAs are stabilized and translated.

  • Introgression of the short arm of rye chromosome one into common wheat increases root biomass and drought tolerance, but the underlying genetic basis is unknown. Here, the authors report that dosage differences in 12-OXOPHYTODIENOATE REDUCTASE genes modulate the differences of wheat root architecture.

  • MEcPP is an evolutionarily conserved metabolite that acts as a plastid-to-nucleus retrograde signal to regulate adaptive responses to fluctuating light. Here the authors show that MEcPP regulates seedling development by stabilizing the phyB photoreceptor in an auxin and Ca2+ dependent manner.

  • MEcPP is an evolutionarily conserved plastidial metabolite functioning as a retrograde signal to the nucleus in response to environmental stresses. Here Jiang et al. show that MEcPP can reduce the abundance of auxin and an auxin transporter, providing a mechanistic link between plastids and adaptive growth responses.
