一种植物维管组织特异表达启动子及其表达载体和应用
摘要：
本发明公开了一种植物维管组织特异表达启动子及其表达载体和应用，植物维管组织特异表达启动子为真菌诱导型启动子，核苷酸序列如SEQNO1所示。含有植物维管组织特异表达启动子的表达载体为pJIT166-pPeTLP2-GFP融合表达载体和pBin-pPeTLP2-GUS融合表达载体。该植物维管组织特异表达启动子可以驱动目的基因在转基因植株的维管部位高效特异表达，在其他部位不表达。应用本发明的启动子在杨树育种工程中，可用来培育抗真菌病杨树新品种。
摘要（英）：

The invention discloses a specific expression promoter of a plant vascular tissue, and an expression vector and an application thereof. The specific expression promoter of the plant vascular tissue is a fungi-induced promoter with a nucleotide sequence shown as SEQNO 1. The expression vector containing the specific expression promoter of the plant vascular tissue is a pJIT166-pPeTLP2-GFP fusion expression vector and a pBin-pPeTLP2-GUS fusion expression vector. The specific expression promoter of the plant vascular tissue can drive target genes to be expressed specifically and efficiently in the vascular positions of transgenic plants and not be expressed in other positions. The promoter can be used for cultivating novel antifungal poplar species in a poplar breeding project.
