摘要: Transcription factor MYB is a critical involved in anthocyanin biosynthesis and abiotic stress resistance of plants. This paper reports the functions codon-optimized transcription VvMYBA6 expressed transgenic Arabidopsis overexpression resulted significant increase content, which also enhanced salt mannitol tolerance Besides, real-time quantitative PCR (qRT-PCR) analysis showed that promoted expression level genes biosynthesis, abscisic acid (ABA) synthesis, proline responses ROS scavenging under stress. According to further stress, significantly increased ABA activities superoxide dismutase (SOD), peroxidase (POD) catalase (CAT), as well reduced content H2O2 malonaldehyde (MDA). The results demonstrated based on increasing synthetic levels Therefore, could be widely used promoting
