  Monocotyledonous plants graft at the embryonic root–shoot interface

  Intra- and inter-specific grafting is possible in most orders of monocotyledonous plants, and this process could be used to combat diseases that affect crops, such as Panama disease in bananas.

  Cell surface and intracellular auxin signalling for H⁺ fluxes in root growth

  Auxin rapidly modulates root growth through simultaneous activation of two opposing mechanisms—TMK1-mediated apoplast acidification and TIR1/AFB-mediated apoplast alkalinization.

  A biosensor for the direct visualization of auxin

  A genetically encoded sensor for the quantitative visualization of auxin distribution in plants enables real-time monitoring of its uptake and clearance by individual cells and within cellular compartments.

  Developmental and biophysical determinants of grass leaf size worldwide

  Relationships between leaf size and vein architecture in more than 1,700 grass species worldwide show that grasses native to colder and drier climates have shorter and narrower leaves that provide them with physiological advantages.

  Temperature-dependent growth contributes to long-term cold sensing

  The authors find that slow plant growth at low temperatures during winter reduces dilution of the transcription factor NTL8, which allows slow accumulation of NTL8 and thus the gradual increase in transcription of VIN3—a gene involved in memory of cold exposure.

  Triggers of tree mortality under drought

  Because climate change is expected to intensify regional-scale droughts, it is important to identify the physiological thresholds that precipitate the mortality of trees and the mechanisms of recovery after drought.

  Embryonic epigenetic reprogramming by a pioneer transcription factor in plants

  The seed-specific transcription factor LEC1 promotes an active chromatin state at the floral repressor FLC and activates its expression in the Arabidopsis pro-embryo, thus reversing the winter cold-induced silenced state that is inherited from gametes.

  Tip-localized receptors control pollen tube growth and LURE sensing in Arabidopsis

  Pollen-specific receptor-like kinase 6 (PRK6), which signals through the guanine nucleotide-exchange factors ROPGEFs, is required for sensing of the LURE1 attractant peptide in Arabidopsis thaliana, and functions together with other PRK family kinases; when introduced into the pollen tubes of the related species Capsella rubella, PRK6 could confer responsiveness to AtLURE1.

  Redox rhythm reinforces the circadian clock to gate immune response

  The master immune regulator NPR1 of Arabidopsis is a sensor of the plant’s redox state and regulates transcription of core circadian clock genes even in the absence of pathogen challenge.

  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.

  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.
