We show here that pectins activate both mitogen-activated protein kinase (MAPK) and multiple gene expression changes associated with cell wall biogenesis and pathogen response in a WAK2-dependent fashion, indicating that WAK2 plays a major role in signaling a diverse array of cellular events in response to pectin in the extracellular matrix.

Jan 16, 2016 · Among them, the Wall-associated kinases (WAKs) have been shown to be positive regulators of fungal disease resistance in several plant species. WAK genes are often transcriptionally regulated during infection but the pathways involved in …

Dec 12, 2024 · Receptor kinases of the WALL-ASSOCIATED KINASE (WAK) family bind pectin and OGs and were previously proposed as OG receptors. However, unambiguous genetic evidence for the role of WAKs in OG responses is lacking.

May 1, 2023 · Here, we show that the wall-associated kinase-like protein RESISTANCE TO FUSARIUM OXYSPORUM 1 (RFO1) is required for plant growth and early defense against Fusarium oxysporum and functions by sensing changes in …

May 8, 2012 · Wall-associated kinases are plasma membrane receptors, appear to be cross-linked to cell wall material, and can be seen by electron microscopy to lie in the cell wall. Pectinase, but not cellulase or other cell wall degrading enzymes …

We show here that pectins activate both mitogen-activated protein kinase (MAPK) and multiple gene expression changes associated with cell wall biogen-esis and pathogen response in a WAK2-dependent fashion, indicating that WAK2 plays a major role in signaling a diverse array of cellular events in response to pectin in the extracellular matrix.

BrWAK1 is the first identified and thoroughly characterized WAK gene conferring disease resistance in Chinese cabbage, and the plant biomass is not significantly influenced by BrWAK1, which will greatly accelerate Chinese cabbage breeding for downy mildew resistance.

Apr 15, 2024 · Here, we investigated the role of Arabidopsis WAKs in OG perception using a novel. 25 deletion mutant of the clustered WAK family. Using a combination of immune assays for early. 27 signaling and immunity, indicating that they are not bona fide OG receptors. 32 sophisticated defense mechanisms.

Feb 6, 2023 · Here, we show that variations in the ectodomain of a cell wall-associated receptor-like kinase, WAK10, in temperate Oryza japonica accessions differentially amplify fluctuations in cell wall integrity to control rice stem height.

Sep 14, 2021 · Signalling pathways for some CSIRs have been very well characterized and involve signal transfer to receptor-like cytoplasmic kinases (RLCKs) and propagation by mitogen-activated protein kinase (MAPK) cascades, influx of calcium (Ca 2+), and associated activation of calcium-dependent protein kinases (CDPKs), leading to the induction of reactive ...
