|a Plants use resistance (R) proteins to detect pathogen effector proteins and activate their innate immune response against the pathogen. The majority of these proteins contain an NB-ARC (nucleotide-binding adaptor shared by APAF-1, R proteins, and CED-4) domain along with a leucine-rich repeat (LRR), and some also bear a toll interleukin 1 receptor (TIR) domain. In this study, we characterized a gene encoding a TIR-NB-ARC-LRR R protein (VpTNL1) (GenBank accession number KX649890) from wild Chinese grapevine Vitis pseudoreticulata accession "Baihe-35-1", which was identified previously from a transcriptomic analysis of leaves inoculated with powdery mildew (PM; Erysiphe necator (Schw.)). The VpTNL1 transcript was found to be highly induced in V. pseudoreticulata following inoculation with E. necator, as well as treatment with salicylic acid (SA). Sequence analysis demonstrated that the deduced amino acid sequence contained a TIR domain at the N-terminus, along with an NB-ARC and four LRRs domains within the C-terminus. Constitutive expression of VpTNL1 in Arabidopsis thaliana resulted in either a wild-type or dwarf phenotype. Intriguingly, the phenotypically normal transgenic lines displayed enhanced resistance to Arabidopsis PM, Golovinomyces cichoracearum, as well as to the virulent bacterial pathogen Pseudomonas syringae pv. tomato DC3000. Similarly, constitutive expression of VpTNL1 in Nicotiana tabacum was found to confer enhanced resistance to tobacco PM, Erysiphe cichoacearum DC. Subsequent isolation of the VpTNL1 promoter and deletion analysis indicated that TC-rich repeats and TCA elements likely play an important role in its response to E. necator and SA treatment, respectively. Taken together, these results indicate that VpTNL1 contributes to PM resistance in grapevine and provide an interesting gene target for the future amelioration of grape via breeding and/or biotechnology
