Deciphering how PAMP manipulation prevents neutrophils from casting NETs in infection 2821 Open
Description Production of phagosomal reactive oxygen species (ROS) drives neutrophil extracellular trap release (NETosis); however, ROS is a universal antimicrobial response, yet only a fraction of neutrophils undergoes NETosis. This indic…

Regulatory Programmes Driving Suberin Plasticity Under Aluminium Stress in Barley Roots Open
Aluminium (Al) toxicity is a major factor limiting plant growth in acidic soils. The beneficial element silicon (Si) can mitigate some effects of Al. However, the impact of Al on suberized apoplastic barriers in roots is largely unknown wh…

Morphological and molecular effects of short-term water deficiency in barley stamen maturation Open
Water deficiency at the reproductive stage of cereal crops mainly affects the development or function of male organs, which causes strong losses in grain yield. We investigated the effects of short-term drought on the post-meiotic maturati…

Hordedane diterpenoid phytoalexins restrict Fusarium graminearum infection but enhance Bipolaris sorokiniana colonization of barley roots Open
Plant immunity is a multilayered process that includes recognition of patterns or effectors from pathogens to elicit defense responses. These include the induction of a cocktail of defense metabolites that typically restrict pathogen virul…

IFI207, a young and fast‐evolving protein, controls retroviral replication via the STING pathway Open
Mammalian AIM-2-like receptor (ALR) proteins bind nucleic acids and initiate production of type I interferons or inflammasome assembly, thereby contributing to host innate immunity. In mice, the Alr locus is highly polymorphic at the seque…

CLAVATA signalling shapes barley inflorescence architecture by controlling activity and determinacy of shoot apical and rachilla meristems Open
Grasses exhibit a large variety of diverse inflorescence architectures, from complex branched inflorescences in Oryzeae (rice) to simple spike-type inflorescences in Triticeae (e.g. barley, wheat). Inflorescence architecture depends on sha…

Contrasting cytosolic glutathione redox dynamics under abiotic and biotic stress in barley as revealed by the biosensor Grx1–roGFP2 Open
Barley is a staple crop of major global importance and relatively resilient to a wide range of stress factors in the field. Transgenic reporter lines to investigate physiological parameters during stress treatments remain scarce. We genera…

A GH81-type β-glucan-binding protein enhances colonization by mutualistic fungi in barley Open
Cell walls are important interfaces of plant-fungal interactions, acting as robust physical and chemical barriers against invaders. Upon fungal colonization, plants deposit phenolics and callose at the sites of fungal penetration to preven…

The transcription factor HSFA7b controls thermomemory at the shoot apical meristem by regulating ethylene biosynthesis and signaling in Arabidopsis Open
The shoot apical meristem (SAM) is responsible for overall shoot growth by generating all aboveground structures. Recent research has revealed that the SAM displays an autonomous heat stress (HS) memory of a previous non-lethal HS event. C…

Metabolic arms race between a plant and a fungal pathogen Open
In this work, we uncover a metabolite interaction between barley and the fungal pathogen Bipolaris sorokiniana ( Bs ), involving hordedanes, a previously undescribed set of labdane-related diterpenoids with antimicrobial properties. Bs inf…
