Development of a salicylic acid inducible minimal sub-genomic transcript promoter from Figwort mosaic virus with enhanced root- and leaf-activity using TGACG motif rearrangement

► Development of a useful promoter by TGACG motif rearrangement. ► It showed enhanced root-activity and salicylic acid inducibility compared to CaMV35S. ► It can be used to constitute efficient plant promoter in conjugation with important cis-elements. ► It is useful for ectopic gene expression in plants. ► It is a minimal promoter (131 bp long) with enhanced activity.
