Pseudomonas syringae is a Gram-negative bacterium that infects multiple plant species by manipulating cellular processes via injection of type three secreted effectors (T3SEs) into host cells. Nucleotide-binding leucine-rich repeat (NLR) resistance (R) proteins recognize specific T3SEs and trigger robust immune response, called effector-triggered immunity (ETI), which limits pathogen proliferation often associated with localized programmed cell death, known as the hypersensitive response...
Abstract Background Cell walls (CWs) are protein-rich polysaccharide matrices essential for plant growth and environmental acclimation. The CW constitutes the first physical barrier as well a primary source of nutrients microbes interacting with plants, such vascular pathogen Fusarium oxysporum (Fo). Fo colonizes roots, advancing through CWs towards vasculature, where it grows causing devastation in many crops. pathogenicity other relies on their capacity to reach colonize xylem. However,...
Controlled primary cell wall remodeling allows plant growth under stressful conditions, but how these changes are conveyed to adjust cellulose synthesis is not understood. Here, we identify the TETRATRICOPEPTIDE THIOREDOXIN-LIKE (TTL) proteins as new members of synthase complex (CSC) and describe their unique hitherto unknown dynamic association with CSC cellulose-deficient conditions. We find that TTLs essential for maintaining high-salinity establishing a stress-resilient cortical...
The plant cell wall is a complex network of polysaccharides and proteins that provides strength structural integrity to cells, as well playing vital role in growth, development, defense response. Cell can be broadly grouped into three categories: cellulose, pectins, hemicelluloses. Dynamic interactions between wall-associated contribute regions flexibility rigidity within the wall, allowing for remodeling when necessary during environmental adaptation, or stress response activation. These...
Abstract Root vascular pathogens are some of the world's most devastating plant pathogens. However, methods used to determine susceptibility this class pathogen laborious, variable, and in cases qualitative. Here we present a rapid, simple, robust infection assay for characterization Arabidopsis thaliana resistance fungal root Fusarium oxysporum . The method utilizes penetrations fungal‐induced growth inhibition deliver quantitative assessment with spatial temporal resolution. These...
Abstract Environmental adaptation of organisms relies on fast perception and response to external signals, which lead developmental changes. Plant cell growth is strongly dependent wall remodeling. However, little known about wall-related sensing biotic stimuli the downstream mechanisms that coordinate defense responses. We generated genetically encoded pH sensors determine absolute changes across plasma membrane in stress. A rapid apoplastic acidification by phosphorylation-based proton...
