  Single gametophyte sequencing reveals that crossover events differ between sexes in maize

  Meiotic crossover (CO) landscape differs inter- and intra-species, as well as between sexes. Here, the authors show that male meiosis produces more COs than female in maize and detect CO maturation inefficiency in some genetic backgrounds, which may help to improve breeding efficiency.

  A heavy metal P-type ATPase OsHMA4 prevents copper accumulation in rice grain

  Copper (Cu) is an essential mineral nutrient but high concentrations in rice grain can cause toxicity. Here the authors provide evidence that natural variation in rice grain Cu concentration is caused by altered sequestration of Cu into root vacuoles due to a single amino acid substitution in the OsHMA4 transporter.

  DELLA-mediated PIF degradation contributes to coordination of light and gibberellin signalling in Arabidopsis

  Gibberellins (GA) negatively regulate light-mediated suppression of hypocotyl elongation in plants. Here, Li et al. show that GA-mediated destabilization of DELLA proteins promotes accumulation of the light-regulated PIF transcription factors thus contributing to the crosstalk between light and GA signalling.

  A phospholipid uptake system in the model plant Arabidopsis thaliana

  P4-type ATPases flip lipids from one side of a membrane to the other. Here Poulsen et al. show that ALA10, a P4 ATPase from Arabidopsis thaliana, internalizes phospholipids from the outside of plant cells and suggest that this uptake may be physiologically important for lipid signalling events.

  Downregulation of N-terminal acetylation triggers ABA-mediated drought responses in Arabidopsis

  N-terminal acetylation is a common protein modification in eukaryotes. Here the authors show that in Arabidopsis, N-terminal acetylation is decreased by drought stress, that abundance of an N-terminal acetyltransferase is reduced by abscisic acid and that constitutive downregulation can confer drought resistance.

  Salicylic acid biosynthesis is enhanced and contributes to increased biotrophic pathogen resistance in Arabidopsis hybrids

  The molecular basis for heterosis, the phenomenon whereby hybrid plants show phenotypic superiority to their parents, remains poorly understood. Here, Yanget al. show that salicylic acid biosynthesis is enhanced in hybrids of Arabidopsis thalianaand correlates with heterosis for pathogen defence.

  CUL4 forms an E3 ligase with COP1 and SPA to promote light-induced degradation of PIF1

  Light exposure to plants initiates a developmental programme known as photomorphogenesis, which is triggered by repression of PIF transcription factors. Here Zhu et al. identify an E3 ubiquitin ligase complex that contributes to photomorphogenesis and is required for the degradation of PIF1.

  Arabidopsis uses two gluconeogenic gateways for organic acids to fuel seedling establishment

  During seed germination plants use gluconeogenesis to mobilize noncarbohydrate energy reserves. Here Eastmond et al. show that plants, unlike other eukaryotes, do not solely rely on a gluconeogenic pathway via the enzyme PCK but also use a second pathway relying on PPDK.

  A megacomplex composed of both photosystem reaction centres in higher plants

  Plants have two types of photosystem reaction centres, PSI and PSII, that are traditionally thought to be spatially separate. Here, Yokono et al. show in Arabidopsisthat around half of PSII physically interacts with PSI to efficiently transfer excitation energy between the complexes, and this interaction is regulated by light.

  The transcriptional regulator BBX24 impairs DELLA activity to promote shade avoidance in Arabidopsis thaliana

  Plants respond to shade by elongating their stems to grow toward the light. Here, Crocco et al. show that the BBX24 transcriptional regulator promotes the shade avoidance response by activating gibberellin signalling and the PIF4 transcription factor under low light conditions.

  The jasmonate-responsive GTR1 transporter is required for gibberellin-mediated stamen development in Arabidopsis

  GTR1 is known to transport glucosinolates in Arabidopsis. Here, Saito et al. show that GTR1 also transports the plant hormones jasmonate and gibberellin when heterologously expressed in Xenopus oocytes, and that gtr1mutant plants show a gibberellin-related fertility phenotype.

  A molecular pathway for CO₂ response in Arabidopsis guard cells

  Carbon dioxide influences plant–water relations and gas exchange by regulating stomatal aperture. Here, Tian et al. characterize RHC1, a MATE family transporter that under elevated carbon dioxide concentrations promotes stomatal closure via activation of the SLAC1 anion channel.
