The flavonoids play important roles in plant salt tolerance. Blueberries (Vaccinium spp.) are extremely sensitive to soil increases. Therefore, improving the resistance of blueberries by increasing flavonoid content is crucial for development blueberry industry. To explore underlying molecular mechanism, we performed an integrated analysis metabolome and transcriptome leaves under stress. We identified 525 differentially accumulated metabolites (DAMs) stress vs. control treatment, primarily including members class. also 20,920 expressed genes (DEGs) based on data; these, 568 transcription factors (TFs) were annotated, bHLH123, OsHSP20, HSP20 TFs might be responsible leaf DEGs involved biosynthesis pathway significantly enriched at almost all stages Salt treatment upregulated expression most biosynthetic promoted accumulation flavonols, flavonol glycosides, flavans, proanthocyanidins, anthocyanins. Correlation suggested that 4-coumarate CoA ligases (4CL5 4CL1) flavonols (quercetin pinoquercetin) flavan-3-ol (epicatechin prodelphinidin C2) stress, respectively. 3′5′-hydroxylases (F3′5′H) regulate anthocyanin (cyanidin 3-O-beta-D-sambubioside delphinidin-3-O-glucoside chloride) biosynthesis, leucoanthocyanidin reductases (LAR) epicatechin C2 during Taken together, it one future breeding goals cultivate salt-resistant varieties genes, especially 4CL, F3′5′H, LAR promote leaves.
