We show that in barley, intracellular mildew A (MLA) R proteins function in the nucleus to confer resistance against the powdery mildew fungus. Recognition of the fungal avirulence AlO effector by MLAIO induces nuclear associations between receptor and WRKY transcription factors. The identified WRKY proteins act as repressors of PAMP-triggered basal defense. MLA appears to interfere with the WRKY repressor function, thereby de-repressing PAMPtriggered basal defense. Our findings reveal a mechanism by which these polymorphic immune receptors integrate distinct pathogen signals. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
