|a Grape ripe rot is one of the most important diseases caused by Colletotrichum spp. Chinese wild grape (Vitis davidii) is highly resistant to Colletotrichum viniferum infection. But mechanisms underlying the resistance remain largely unclear. In this study, transcriptomic and metabolomic responses of V. davidii to C. viniferum were studied before and after 1, 2, 4, and 6 days of inoculation. C. viniferum infection induced the expression of a large number of defense-related genes. KEGG analysis indicated that the differentially expressed genes (DEGs) were largely those involved in alpha-linolenic acid metabolism, flavonoid biosynthesis, phenylpropanoid biosynthesis, stilbenoid biosynthesis, and other defense-related metabolic pathways. Based on transcriptome data and experimental analysis, we found that jasmonic acid (JA) biosynthesis was closely related to V. davidii resistance to C. viniferum. In addition, many genes related to the synthesis of lignin and phytoalexin resveratrol are upregulated by pathogen infection, and metabolomic analysis showed that there was an increasing accumulation of resveratrol on day 6 of C. viniferum inoculation. Further analysis indicated that transcription factors, such as VdWRKY75 regulated the biosynthesis of lignin and stilbenes. A working model for V. davidii against C. viniferum infection was proposed. The infection of C. viniferum induced JA production, JA along with transcription factors regulated the biosynthesis of secondary metabolites, such as lignin and resveratrol that enhanced plant resistance to C. viniferum. This study elucidated molecular mechanisms underlying the resistance of Chinese wild V. davidii to C. viniferum which can provide a theoretical basis for grape disease resistance breeding
