The construct pCHW-2 consisting of DBP12 promoter(Genbank Accession No:DQ497621)of Dl- BADH1(Genbank Accession No:DQ011151)gene from Dendranthema lavandulifolium L.genome was trans- ferred into tobacco plants via A grobacterium tumefaciens EHA105.The regenerated plants were analyzed by GUS histo-chemical staining.The results showed that the expression of GUS gene under the control of DBPl2 promoter was no tissue-specific.Under the treatments of NaCl,ABA and SA stress,the expression efficiency of the promot- er in transgenic plants were analyzed by GUS activity assay.The level of GUS activity in the leaves of transgenic tobacco plants increased steadily after 24 h exposure tO 100μmol/L ABA and 48 h exporsure to 400 mmol/L Na- Cl,which could imply that DBPl2 promoter of DlBA DH1 gene should be an inducible promoter.The results might provide a reference for further studies on expression pattern of BADH gene in Dendranthema lavandulifolium.
