The transcription factorMYB15plays an important role in grape basal immunity, and its promoter can be used as a potential target in resistance breeding. However, the regulatory mechanisms ofcis-elements in its promoter region under a variety of stresses remain unclear. In this study, we identified some putativecis-regulatory elements present upstream ofMYB15inVitis quinquangularisShanyang (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 keycis-regulatory elements inpVqMYB15_SY and play important roles in plant bio/abiotic stress resistance.
