摘要： The qualities of grapes and wine are influenced by geographical location. How geographical location affects the quality of grapes and how grape root responses to the location on small-scale remained uncertain. This study aimed to investigate the changes of root transcriptome characteristics and quality of wine grapes at small-scale location. Wine grapes (V. vinifera L. cv. Cabernet sauvignon) were planted at four planting locations (ZH (Zhihui), YQY (Yuquanying), LL (Lilan), and HSB (Hongsibao)) for four years. Total NPK and available micronutrients of grape leaf were measured, and anthocyanin, total phenols, tannin, and titratable acid of grape berry were analyzed. The root transcriptome was also analyzed. The grapevine at HSB location had higher contents of Fe, Cu, Mn, Zn, and B. In contrast with ZH location, grapevine at the other three locations produced higher tannin contents, and lower contents of soluble solids, titratable acid, and anthocyanin. A total of 5010 (YQY vs. ZH), 6284 (LL vs. ZH), 4119 (HSB vs. ZH), 1623 (HSB vs. YQY), 6360 (HSB vs. LL), and 6770 (YQY vs. LL) DEGs (differentially expressed genes) were identified by t-test. These DEGs were associated with some pathways, including 'Flavonoid biosynthesis', 'Phenylpropanoid biosynthesis', 'Glutathione metabolism', and 'Nitrogen metabolism'. Transcription factors (ERF, NAC, WRKY, and MYB) and small heat shock proteins differentially expressed between groups. In conclusion, small-scale location differences altered grape root genetic characteristics, mainly involving plant resistance and defense. However, the relationships between DEGs and mineral elements and the quality of wine grapes are complex and need further investigation.
