摘要： Stem lignification leads to decline in quality and restricts the shelf life of Chinese flowering cabbage. However, the role of transcription factors in this process is unclear. This study demonstrates that modified atmosphere packaging (MP30) effectively delayed lignification and lignin accumulation during postharvest storage. Moreover, a novel WRKY transcriptional activator (BrWRKY70) was identified, whose expression upregulated during storage but was suppressed by MP30. BrWRKY70 directly activated downstream lignin synthetic genes BrPAL3, BrPODC3, and BrPOD69 by binding to their promoters. Additionally, functional validation in Arabidopsis thaliana showed that BrWRKY70 accelerated lignin and flavonoid synthesis via upregulating the expressions of related genes. Our findings suggest that BrWRKY70 acts as a transcriptional activator, promoting lignin synthesis and accelerating stem lignification in Chinese flowering cabbage.
