Transcriptome Analysis of Berries of Spine Grape (Vitis davidii Föex) Infected by Colletotrichum viniferum during Symptom Development

Grape ripe rot (Colletotrichum viniferum) causes huge losses in grape production vineyards southern China. However, the molecular mechanism against species and responsive genes implicated these processes are relatively unknown. Here, we present transcriptome analysis of berries from a C. viniferum-resistant (Vitis davidii Föex). Uninfected at day zero were used as control samples (CK), an inoculation was made zero, subsequently analyzed 1 day, 3 days, 7 days post (dpi), which exhibited sequential disease-progression stage. There total 1810 differentially expressed genes, including 1315 up-regulated 495 down-regulated transcripts. At dpi, (DEGs) predominantly enriched berries. In addition, viniferum-infected fruits considerable changes gene expression induced, those involved MAPK cascade, calcium ion binding, serine/threonine kinase activity enriched. According to our KEGG pathway analysis, numerous biological processes, such plant–pathogen interaction, phenylpropanoid biosynthesis, metabolism, grape–fungus interactions. Our research also revealed alterations pattern phenylalanine-pathway-related transcription factors (TFs) genes. We proposed model viniferum invasion produces intracellular extracellular Ca2+ deregulation stimulate activate TFs’ (WRKY, ERF, MYB) up-regulation, thus initiating disease-resistant responses tolerant Vitis species. results offer comprehensive transcriptomic data about grape, will aid understanding underlying plant viniferum.
