520 |a The grape aspartic protease gene, AP13 was previously reported to be responsive, in Chinese wild Vitis quinquangularis cv. 'Shang-24', to infection by Erysiphe necator, the causal agent of powdery mildew disease, as well as to treatment with salicylic acid in V. labrusca×V. vinifera cv. 'Kyoho'. In the current study, we evaluated the expression levels of AP13 in 'Shang-24' in response to salicylic acid (SA), methyl jasmonate (MeJA) and ethylene (ET) treatments, as well as to infection by the necrotrophic fungus, Botrytis cinerea, and the transcript levels of VqAP13 decreased after B. cinerea infection and MeJA treatment, but increased following ET and SA treatments. Transgenic Arabidopsis thaliana lines over-expressing VqAP13 under the control of a constitutive promoter showed enhanced resistance to powdery mildew and to the bacterium Pseudomonas syringae pv. tomato DC3000, and accumulated more callose than wild type plants, while the resistance of transgenic A. thaliana lines to B. cinerea inoculation was reduced. In addition, the expression profiles of various disease resistance- related genes in the transgenic A. thaliana lines following infection by different pathogens were compared to the equivalent profiles in the wild type plants. The results suggest that VqAP13 action promotes the SA dependent signal transduction pathway, but suppresses the JA signal transduction pathway
