Tm-22基因转化烟草并获得表达,表明Tm-22基因的功能在同科不同属的植物体上没有改变.但是转基因烟草的T2代出现了许多生物学性状的变异,例如,无花粉花药、花瓣呈浅色、植株体矮化、种苗黄化等,这种变异性状的产生不仅有外源基因重组的因素,也是该基因与其它基因相互作用的结果.这些变异的个体为研究该基因的功能及其遗传变异规律提供了丰富的材料.
The Tm-22 gene was transformed into tobacco and expressed, indicating that the function of Tm-22 gene did not change in plants belonging to different genera.But T2 generation of transgenic tobacco showed many biological traits variation, for example, pollen anthers, Petals were light, plant dwarf, seedling yellow, etc. This variability traits not only have exogenous gene recombination, but also the gene and other genes as a result of the interaction of these individuals to study the gene The function and genetic variation provides a wealth of materials.
