    The authors characterize a cross-talk between ABA and energy pathways. Essential ABA signalling components SnRK2s sequester SnRK1 in a protein complex, decreasing its interaction with the TOR kinase central for energy signalling.

    Genomic analyses of 101 plant species reveals a fundamental shift in the proportion of repetitive sequences in genomes above around 10 Gbp—species with the largest genomes are only about 55% repetitive, and this proportion does not increase further with genome size.

    Ending hunger is a major objective of the United Nations’ Sustainable Development Goals. A cross-journal collection of articles takes a systematic look at what we might already know about achieving it.

  • Perspective |

    The United Nations’ Sustainable Development Goal 2 encompasses targets ranging from the eradication of hunger and malnutrition to ensuring a sustainable food production system. Conflicts between these goals gives rise to gaps in our understanding that hamper attempts at evidence-based policy-making.

    Polar cell growth requires spatiotemporal regulation of Rho of plants (ROPs) small G proteins in membrane domains. In addition to localized activation of membrane-anchored ROPs, a mechanism for their local inactivation has now been identified.

    Cell polarity that requires asymmetrical distribution of cellular components is important for plant growth and development. Here the authors identify a group of ARMADILLO domain proteins that collectively act in the polarized cell expansion of tip-growing cells by recruiting Rho of plant 1 (ROP1) enhancer GTPase-activating proteins and therefore ROP signalling to distinct plasma membrane sites.

    Plant roots have to orchestrate their growth pattern to access available nutrients. Root architecture is governed by auxin that locally steers growth and development of lateral roots, thereby increasing the uptake capacity. A new mechanism for ammonium acquisition by influencing cellular auxin import has been defined.

    In the Gospel According to Matthew Chapter seven, Verse five, Jesus says “first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye”. We should remember this entreaty before too casually casting accusations of ‘plant blindness’.

    Ammonium and nitrate are the two major forms of inorganic nitrogen in soils. Ammonium shapes root architecture of plants by triggering lateral root branching. Here the researchers investigated the mechanism involving pH-dependent import of protonated auxin into the cortical and epidermal cells overlaying lateral root primordia.

    Quinones are small secondary metabolites synthesized by a broad range of organisms. Perception of these aromatic molecules in plants involves membrane-bound LRR-RLKs to induce downstream cellular responses in plants such as calcium fluxes, specific gene expression and MAPK activation.

    The excess application of nitrogen fertilizer in agriculture and the limitation of nitrogen uptake by crops raise the alarm about the urgency to breed crops with higher nitrogen use efficiency (NUE). Recently, a novel strategy has been developed to enhance NUE and crop production by manipulating nitrate remobilization.

    One important direction to reduce the application of nitrogen fertilizer is to improve nitrogen use efficiency (NUE) of crops. Now an interesting strategy that engineers the transporter responsible for source-to-sink nitrate remobilization is employed to generate transgenic Arabidopsis, tobacco and rice lines with enhanced NUE and plant yield.

    The battle between humans and plant pests is as old as agriculture, but the movement of pests as a consequence of human activities has been exacerbated only recently. International research collaboration is increasingly important to tackle pests causing serious damage to economies.
