Abstract:
Brassinolide Enhanced Expression(
BEE) genes belong to bHLH transcription factors family, and were involved in Brassinolide signal pathway. In this study, the promoter of
BpBEE1 gene was cloned, and regulatory elements in the promoter regions were analyzed using the online program PLACE. The results showed that the
BEE1 promoter sequence contained various hormone responses elements. The results showed that the GUS activity was increased in the veins and roots, and the activity of promoter was enhanced after MeJA, SA, BL and ABA treatment, especially MeJA, SA and BL treatment. We propose that
BpBEE1 is involved in hormone response, and play a role in the process of plant growth and development.
