Popis: Innate immunity in plants relies on the recognition of pathogen-associated molecular patterns (PAMPs) by pattern-recognition receptors (PRRs) located on the plant cell surface. CaLecRK-S.5, a pepper L-type lectin receptor kinase, has been shown to confer broad-spectrum resistance through priming activation. To further elucidate the molecular mechanism of CaLecRK-S.5, transgenic tobacco plants were generated in this study. Interestingly, hemizygous transgenic plants exhibited a high accumulation of CaLecRK-S.5, but this accumulation was completely abolished in homozygous transgenic plants by a cosuppression mechanism. Gain-of-function and loss-of-function analyses revealed that CaLecRK-S.5 plays a positive role in Phytophthora elicitin-mediated defense responses.
