| 6 | Perception of unrelated microbe-associated molecular patterns triggers conserved yet variable physiological and transcriptional changes in Brassica rapa ssp.pekinensis显示文摘Pattern-triggered immunity(PTI)includes the different transcriptional and physiological responses that enable plants to ward off microbial invasion.Surface-localized pattern-recognition receptors(PRRs)recognize conserved microbeassociated molecular patterns(MAMPs)and initiate a branched signaling cascade that culminate in an effective restriction of pathogen growth.In the model species Arabidopsis thaliana,early PTI events triggered by different PRRs are broadly conserved although their nature or intensity is dependent on the origin and features of the detected MAMP.In order to provide a functional basis for disease resistance in leafy vegetable crops,we surveyed the conservation of PTI events in Brassica rapa ssp.pekinensis.We identified the PRR homologs present in B.rapa genome and found that only one of the two copies of the bacterial Elongation factor-Tu receptor(EFR)might function.We also characterized the extent and unexpected specificity of the transcriptional changes occurring when B.rapa seedlings are treated with two unrelated MAMPs,the bacterial flagellin flg22 peptide and the fungal cell wall component chitin.Finally,using a MAMP-induced protection assay,we could show that bacterial and fungal MAMPs elicit a robust immunity in B.rapa,despite significant differences in the kinetic and amplitude of the early signaling events.Our data support the relevance of PTI for crop protection and highlight specific functional target for disease resistance breeding in Brassica crops. | Wanhui Kim Maxim Prokchorchik Yonghua Tian Seulgi Kim Hyelim Jeon Cécile Segonzac | 2020 | Horticulture Research2020，7，1： | 0 |
| 7 | A plasma membrane nucleotide-binding leucinerich repeat receptor mediates the recognition of the Ralstonia pseudosolanacearum effector RipY in Nicotiana benthamiana显示文摘Bacterial wilt disease caused by several Ralstonia species is one of the most destructive diseases in Solanaceae crops.Only a few functional resistance genes against bacterial wilt have been cloned to date.Here,we showthat the broadly conserved typeⅢsecreted effector RipY is recognized by the Nicotiana benthamiana immune system,leading to cell death induction,induction of defense-related gene expression,and restriction of bacterial pathogen growth.Using a multiplexed virus-induced gene-silencing-based N.benthamiana nucleotide-binding and leucine-rich repeat receptor(NbNLR)library,we identified a coiled-coil(CC)nucleotide-binding and leucine-rich repeat receptor(CNL)required for recognition of RipY,which we named RESISTANCE TO RALSTONIA SOLANACEARUM RIPY(RRS-Y).Genetic complementation assays in RRS-Y-silenced plants and stable rrs-y knockout mutants demonstrated that RRS-Y is sufficient to activate RipY-induced cell death andRipY-induced immunity to Ralstonia pseudosolanacearum.RRS-Y function is dependent on the phosphate-binding loop motif of the nucleotide-binding domain but independent of the characterized signaling components ENHANCED DISEASE SUSCEPTIBILITY 1,ACTIVATED DISEASE RESISTANCE 1,and N REQUIREMENT GENE 1 and the NLR helpers NB-LRR REQUIRED FOR HR-ASSOCIATED CELL DEATH-2,-3,and-4 in N.benthamiana.We further show that RRS-Y localization at the plasma membrane is mediated by two cysteine residues in the CC domain and is required for RipY recognition.RRSY also broadly recognizes RipY homologs across Ralstonia species.Lastly,we show that the C-terminal region of RipY is indispensable for RRS-Y activation.Together,our findings provide an additional effector/receptor pair system to deepen our understanding of CNL activation in plants. | Boyoung Kim Wenjia Yu Haseong Kim Qian Dong Sera Choi Maxim Prokchorchick Alberto PMacho Kee Hoon Sohn Cécile Segonzac | 2023 | Plant Communications2023，4，6： | 0 |
