Promoter enhancer element for gene expression in plant roots

摘要

Detection of a cellular factor from pea and tobacco which binds to a repeated pentameric motif of TGACG present in the -90 to -60 region of the CaMV 35S promoter is disclosed. Also disclosed is a 21 bp promoter element which is capable of imparting root expression capability to a rbcS-3A promoter, normally a green tissue specific promoter.
