Abstract:
The vsp1 gene of Arabidopsis thaliana encodes a storage protein that accumulates in vegetative organs. Transgenic plants expressing a vsp1 promoter-gus (beta-glucuronidase) gene fusion were found to contain high GUS activity when challenged with jasmonate, a volatile plant hormone. The induction of vsp1-gus expression by jasmonate could be measured in tobacco mesophyll protoplasts, after transient expression. A number of deletions were operated in the vsp1 promoter in order to locate its jasmonate-responsive element. A 41 bp sequence taken approximately 150 bp upstream of the vsp1 TATA box could confer jasmonate responsiveness upon a short CaMV 35S promoter. Whereas the deletion of a CAAT box-like element within the 41 bp sequence did not affect promoter activity, mutation of a short palindromic motif completely abolished jasmonate responsiveness. This motif shows no homology with the jasmonate-responsive elements of other promoters.
