Abstract
Synthetic pathogen inducible promoters are used for the improvement and application of transgenic techniques in research and to increase agriculture production. The promoter contains specific cis-regulatory elements (W box, GCC box, Box S and D box) which induce anti pathogen molecular cascades. Insertion of dimerized form of cis acting elements at upstream region of promoter in promoter probe vector drives the expression of resistance gene or reporter gene. The expression indicates that synthetic promoters are responded to fungal elicitors. Expression of resistance restrict to infection sites which boost disease resistance in plants.
