摘　　要：将枯草芽孢杆菌纤溶酶(Bacillussubtilisfibrinolyticenzyme,BSFE)基因及其信号肽序列转入烟草,转基因烟草表现出不同于野生型烟草的生长特性,如营养器官生长速率下降、叶片数目减少、叶片狭长、叶片宽度/叶片长度值降低以及植株矮小、节间缩短等。推测其与外源BSFE的蛋白水解活性有关。The trans - BSFE gene tobacco, compared with the common tobacco, showed apparent growth difference. For example, the growth rate of vegetative organ dropped, leaves became less and more narrow and longer, the ratio of the wideth to the length of leaves decreased, the height of plants turned smaller and interrodes was shorter, etc. it can be infered that those changes relate with the guidance and expression of exogenesis BSFE gene.
