由于植物转基因技术的发展,使烟草获得马铃薯Y病毒(PVY)抗性成为可能。然而,一个转入基因的存在可能会使除了目标性状以外的其它性状也发生改变。因此,对获得的转基因株系的农艺性状和生物学性状进行评估就显得很有必要。在这项研究中,我们研究了属于由3种遗传结构修饰的4个栽
Due to the development of plant transgenic technology, it is possible for tobacco to acquire potato-Y virus (PVY) resistance. However, the presence of a transgene may alter other traits other than the target trait. Therefore, it is necessary to evaluate the agronomic traits and biological characters of the obtained transgenic lines. In this study, we studied 4 plants belonging to the three genetic structures
