Summary Pathogens secret a plethora of effectors into the host cell to modulate plant immunity. Analysing role in altering function their target proteins will reveal critical components immune system. Here we show that Phytophthora infestans RXLR effector PITG20303, virulent variant AVRblb2 (PITG20300) escapes recognition by resistance protein Rpi‐blb2, suppresses PAMP‐triggered immunity (PTI) and promotes pathogen colonization targeting stabilizing potato MAPK cascade protein, StMKK1. Both...

Abstract Phytophthora species are destructive plant pathogens that cause significant crop losses worldwide. To understand susceptibility to oomycete and explore novel disease resistance strategies, we employed the Arabidopsis thaliana–Phytophthora parasitica model pathosystem screened for A. thaliana T‐DNA insertion mutant lines resistant P. . This led identification of 267‐31, which carries two sites in promoter region ethylene‐responsive factor 19 gene ( ERF019 ). Quantitative reverse...

Abstract Mitogen-activated protein kinase (MAPK) cascades play important roles in plant immunity. Previously, we reported that the potato StMKK1 negatively regulates Nicotiana benthamiana resistance to Phytophthora infestans . However, functions of immunity are unknown. To investigate different pathogens, such as late-blight pathogen P. , bacterial wilt Ralstonia solanacearum and gray-mold fungal Botrytis cinerea generated transgenic lines investigated response transformants destructive...

A cascade formed by phosphorylation events of mitogen-activated protein kinases (MAPKs) takes part in plant stress responses. However, the roles these MAPKs resistance potato (Solanum tuberosum) against Phytophthora pathogens is not well studied. Our previous work showed that a infestans RXLR effector targets and stabilizes negative regulator MAPK kinase 1 (StMKK1). Because Arabidopsis thaliana AtMPK4 downstream target AtMKK1, we performed phylogenetic analysis found StMPK4/6/7 are closely...

Abstract Mitogen‐activated protein kinase (MAPK) cascades play pivotal roles in plant responses to both biotic and abiotic stress. A screen of a Nicotiana benthamiana cDNA virus‐induced gene silencing (VIGS) library for altered inoculation with Phytophthora infestans previously identified an NbMKK gene, encoding clade D MAPKK that we renamed as NbMKK5 , which is involved immunity P. . To study the role potato orthologous referred StMKK5 response transiently overexpressed N. observed cell...

Mitogen-activated protein kinase (MAPK) cascades play pivotal roles in regulating plant immunity. MAPKs usually transduce signals and regulate immunity by phosphorylating the downstream defence-related components. Our previous study indicates that StMPK7 positively regulates defence to Phytophthora pathogens via SA signalling pathway. However, component of remains unknown. In this study, we employed GFP-StMPK7 transgenic potato performed immunoprecipitation-mass spectrometry (IP-MS) identify...
