    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.

    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.

    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.

    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.

    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.

    LONG HYPOCOTYL 5 (HY5) is a central transcription factor that acts downstream of CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) during light signalling. Here, the authors show that three B-box containing proteins (BBX) are cofactors of HY5 and modulate transcriptional responses for a subset of HY5-dependent processes.

    Short interfering RNA (siRNA) can silence genes in neighbouring and distant plant cells. The authors show that transgenes, endogenous genes and viruses are silenced through the movement of free primary siRNA duplexes, which are progressively diluted and simultaneously selectively depleted during this process.
