The synthetic oligomers called nos right palindrome (RP) element and left palindrome (LP) element were inserted into nos.minimal promoter nos 5'-101 deletion mutant The activity of nos promoter was measured by studying the expression pattern of gene fusion between nos promoter and reporter genes such as chloramphenicol acetyltransferase and $\beta$-glucuconidase. Analysis of transgenic tobacco plane carrying transgene showed that the activity of nos minimal promoter activity was recovered by insertion of synthetic nos RP element. Nos RP element insertion of nos minimal promoter was induced by auxin, dithiothreitol, salicylic acid and methyl jasmonate.
