Significance Cell-fate determination and cellular behavior in plants rely mainly on positional information intercellular communication. A plethora of cues are perceived by surface receptors integrated into an adequate output. Here, we show that the small receptor-like protein RLP44 acts as intermediary to connect for two well-known signaling molecules, brassinosteroid phytosulfokine, control cell fate root vasculature. Furthermore, receptor has functions independent from responses its...
Most organisms adjust their development according to the environmental conditions. For majority, this implies sensing of alterations cell walls caused by different cues. Despite relevance process, few molecular players involved in wall are known and characterized. Here, we show that wall-associated kinase-like protein RESISTANCE TO FUSARIUM OXYSPORUM 1 (RFO1) is required for plant growth early defense against Fusarium oxysporum functions changes pectin methylation levels wall. The RFO1 dwell...
Transcription factors of the basic leucine zipper (bZIP) family control development and stress responses in eukaryotes. To date, only one bZIP has been described any oomycete; oomycetes are members stramenopile kingdom. In this study, we describe identification 38 bZIPs from Phytophthora infestans genome. Half contain novel substitutions DNA-binding domain at a site that other eukaryotes is reported to always be Asn. Interspecific comparisons indicated (usually Cys, but also Val Tyr) arose...
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...
Abstract Multicellularity arose independently in plants and animals, but invariably requires robust determination maintenance of cell fate. This is exemplified by the highly specialized water-and nutrient-conducting cells plant vasculature, which are specified long before their commitment to terminal differentiation. Here, we show that hormone receptor BRASSINOSTEROID INSENSITIVE 1 (BRI1) required for root vascular fate maintenance, as BRI1 mutants ectopic xylem procambial position. However,...
