    The bacterial effector proteins of the AvrE family function as membrane channels in plant cells, enabling the passage of water and solutes from host cells to support pathogen growth, and disrupting the viability of the host cell.

    Aphid-transmitted viruses encode proteins that suppress the plant airborne defence response—which is triggered by volatile chemicals released by neighbouring plants after aphid attack—and the plants consequently become less repellent to aphids and more suitable for aphid survival, infestation and viral transmission.

    Arabidopsis thaliana UMAMIT uniporters facilitate glucosinolate efflux from biosynthetic cells along the electrochemical gradient into the apoplast, in which the high-affinity H+-coupled glucosinolate importers GLUCOSINOLATE TRANSPORTERS (GTRs) load them into the phloem for translocation to the seeds.

    The tomato spotted wilt orthotospovirus nonstructural protein NSs interferes with phytohormone signalling in plants to compromise plant defences by interacting with plant TCP21—this effect of the viral protein is counteracted by the plant NLR immune receptor protein Tsw.

    Evolutionary conservation of plant receptor structure allowed for generation of new variants of wheat and barley nucleotide-binding leucine-rich repeat receptors (NLRs) that recognize AvrSr35 of the wheat stem rust pathogen, supporting proof of principle for structure-based engineering of NLRs for crop improvement.

    A structural analysis focusing on plant immunity reveals how LRR-containing receptor-like proteins recognize pathogenic ligands and consequently become activated, with the data suggesting that these proteins target pathogens through two different mechanisms.

    Suppression of salicylic acid production in Arabidopsis thaliana at high temperature is caused by decreased recruitment of GUANYLATE BINDING PROTEIN-LIKE 3 defence-associated condensates on promoter sites of master immune regulatory genes.

    Cryo-electron microscopy and crystal structures of Arabidopsis NPR1—a bird-shaped homodimer—and its complex with the transcription factor TGA3 provide an explanation for a direct role of salicylic acid and enhanceosome assembly in regulating NPR1-dependent gene expression.

    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.

    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.

    Structural determination of the salicylic-acid-binding core of Arabidopsis NPR4 sheds light on the mechanisms through which this plant hormone interacts with its receptors, providing insights that are of potential use in engineering enhanced immunity.

    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.

    The cyclic nucleotide-gated channel proteins CNGC2 and CNGC4 form a calcium channel in Arabidopsis; this channel is blocked by calmodulin in the resting state but is phosphorylated and activated upon pathogen attack, triggering an increase in cytosolic calcium levels.

    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.

    A combination of high humidity and bacterial effectors, such as Pseudomonas syringae HopM1, creates an aqueous environment in the apoplast of immunodeficient Arabidopsis thaliana that allows non-pathogenic P. syringae strains to become virulent pathogens.

    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.

    A remarkable example has been discovered of a plant tuning its immune defence against a pathogen. The tuning consists of maximal expression of the relevant genes at the time of day when attack is most likely. See Letter p.110

    Circadian rhythms regulate a wide variety of developmental and metabolic processes resulting in enhanced fitness. In this study, a link is made between plant immune responses and the circadian clock. Plant defence against a fungal pathogen which causes downy mildew disease in Arabidopsis is studied, and it is shown that a novel set of defence genes are regulated by the circadian regulator CIRCADIAN CLOCK-ASSOCIATED 1 (CCA1). The mechanism allows plants to 'anticipate' infection at dawn when the pathogen normally disperses its spores. Such a cross-talk mechanism reveals an important strategy for plants to time immune responses against pathogens.

    Sugar efflux transporters are essential for diverse processes such as nectar production and seed and pollen development, as well for the maintenance of blood glucose levels in animals. These authors identify and characterize a novel sugar transporter family, SWEET, and show that several Arabidopsis, rice and metazoan homologues mediate glucose transport. In addition, some of these transporters are exploited by plant pathogens for nutritional gain and virulence.

    Plants and animals sense intruding pathogens by using proteins that recognize diverse microbe-associated molecular patterns (MAMPs) and initiate innate immune responses. Early signalling responses in the host include calcium influx, an oxidative burst and transcriptional reprogramming. Here, four calcium-dependent protein kinases are described that function as calcium sensors, act as convergence points for various MAMPs, and are crucial for transcriptional reprogramming and oxidative burst in plants.
