We characterized promoter activity of a phenylpropanoid biosynthetic gene encoding 4-coumarate Co-A ligase (4CL), Pta4Clα, from Pinus taeda. Histochemical- and quantitative assays of GUS expression in the vascular tissue were performed using transgenic tobacco plants expressing promoter-GUS reporters. Deletion analysis of the Pta4Clα promoter showed that the region ?524 to ?252, which has two AC elements, controls the high expression levels in ray-parenchyma cells of older tobacco stems. High activity level of the promoter domain of Pta4CLα was also detected in the xylem cells under bending stress. DNA-protein complexes were detected in the reactions of the Pta4CLα promoter fragments with the nuclear proteins of xylem of P. taeda. The AC elements in the Pta4CLα promoter appeared to have individual roles during xylem development that are activated in a coordinated manner in response to stress in transgenic tobacco. 相似文献
