    Insect salivary protein (BISP) targets OsRLCK185 to suppress defence in susceptible plants, whereas in resistant plants BISP binds BPH14 to activate host plant resistance. To restore cellular homeostasis, the resistance mechanism is fine-tuned by selective autophagy.

    A plant endogenous peptide-receptor signaling pathway termed SCREW–NUT is described; it counteracts microbe-associated molecular pattern (MAMP)- and abscisic acid-induced stomatal closure to regulate the reopening of stomata after biotic and abiotic stresses.

    Dimethoxy-1,4-benzoquinone signalling occurs in Arabidopsis and in the root parasite Phtheirospermum japonicum via increases in cytosolic Ca2+ concentration mediated by the leucine-rich-repeat receptor-like kinase CARD1 in Arabidopsis, or by its homologues in P. japonicum.

    A study in Arabidopsis thaliana shows that the immune receptor-associated cytosolic kinase BIK1 phosphorylates OSCA1.3 and identifies OSCA1.3 as the pathogen-responsive Ca2+-permeable channel that regulates stomatal closure.

    The adaptability of the plant Arabidopsis thaliana to different temperatures is regulated by the ability of its ELF3 protein to undergo liquid–liquid phase separation, in a manner that is dependent on the protein’s prion-like domain.

    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.

    A systems-level map of the Arabidopsis hormone signalling network, comprising more than 2,000 binary protein–protein interactions, reveals hundreds of interpathway contact points, many of which mediate crosstalk between different hormone pathways.

    Many of the molecular targets of strigolactones—plant hormones involved in development and in interactions with symbiotic and parasitic organisms—are uncovered, revealing how strigolactones function and an intriguing role for self-regulation of a downstream transcription factor.

    The detection of microorganism-associated ligands by plant cells activates a signalling cascade in which the kinase BIK1 is monoubiquinated, released from the FLS2–BAK1 complex, and internalized by endocytosis.

    RITF1, a newly identified plant transcription factor, links signalling through the peptide hormone RGF1 to the balance of reactive oxygen species and thereby enhances the stability of another transcription factor, PLETHORA2, a master regulator of root stem cells.

    Hypoxia in the shoot meristem of Arabidopsis links the regulation of metabolic activity to development by inhibiting proteolysis of a substrate of the N-degron pathway, which controls class-III homeodomain-leucine zipper transcription factors.

    The plant receptor kinase co-receptor BAK1 contains phosphosites that are required for immune function but not for brassinosteroid-regulated growth in Arabidopsis thaliana; an additional tyrosine phosphosite may be required for the function of many Arabidopsis receptor kinases.

    Structural, biochemical, mass spectrometry and genetic analyses define Arabidopsis thaliana AtD14 as a non-canonical hormone receptor for strigolactone, which hydrolyses strigolactone into a covalently linked intermediate molecule and undergoes an open-to-closed state transition for interaction with D3 to trigger strigolactone signalling.

    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.

  • Letter |

    A male cell-surface receptor-like kinase that responds to the female chemoattractant LURE1 on the pollen tube of Arabidopsis thaliana is identified; LURE1 triggers dimerization of the receptor components and activation of the kinase activity, and the transformation of a component of the A. thaliana receptor to the Capsella rubella species partially breaks down the reproductive isolation barrier.

    Insights derived from the crystal structures of the extracellular domain of PSKR, the receptor for the plant hormone phytosulfokine (PSK) that affects plant growth and development, reveal that PSK interacts with PSKR and enhances PSKR interaction with its co-receptor SERK allosterically.

    An investigation of the molecular mechanism of stomatal development and patterning finds an unexpected signalling mechanism: two signalling peptides (STOMAGEN, a positive regulator of stomatal development; and EPF2, a negative regulator of this process) use the same receptor kinase, ERECTA, to fine-tune stomatal development.

    A new mechanism that plants use to combat begomoviruses—one of the most pathogenic groups of plant viruses, causing severe disease in major crops worldwide—is uncovered: plants inhibit the transcription of genes associated with the translational apparatus, thus causing a general reduction in protein synthesis.
