520 |a Epidermal wax plays a critical role in plant resistance and fruit storage properties. As such, the regulation of wax production is of great importance in fruit, but there is limited information about this process in citrus plants. In this study, we investigated the role of the Citrus sinensis transcription factor CsMYB30 in the regulation of wax synthesis by cloning and ectopically expressing the gene in Arabidopsis and examining the effects on wax formation and stress tolerance. CsMYB30 transgenic Arabidopsis plants showed improved tolerance to salt and drought stresses compared to their wild-type counterparts. Ectopic expression of CsMYB30 also caused changes to the microstructure of wax crystals and wax composition, a significant increase in wax load, and a decrease in the permeability of leaf epidermis. Additionally, most genes related to the wax synthesis pathway were upregulated at the transcription level. These findings suggest that CsMYB30 is a transcriptional regulator of wax production in citrus and can serve as a potential target gene in genetic engineering or breeding efforts to improve citrus fruit resistance and storage performance
