Function analysis and stress-mediated cis-element identification in the promoter region of VqMYB15

Year: 2020

Type: article

Abstract: The transcription factor MYB15 plays an important role in grape basal immunity, and its promoter can be used as a potential target in resistance breeding. However, the regulatory mechanisms of cis-elements in its promoter region under a variety of stresses remain unclear. In this study, we identified some putative cis-regulatory elements present upstream of MYB15 in Vitis quinquangularis Shanyang (pVqMYB15_SY) and subsequently characterized the function of these elements using reporter assays. Our results showed that TCA-elements 1 and 2, ABRE, MYC and 3-AF1 binding site 1 are key cis-regulatory elements in pVqMYB15_SY and play important roles in plant bio/abiotic stress resistance.
