Mechanism of schizaphis graminum in transmitting maize dwarf mosaic virus 麦二叉蚜传播玉米矮花叶病毒的机制
2.
The pap gene was also transformed into wheat by pollen tube pathway - mediated and 320 grains of transgenic wheat was harvested . the seedlings of the seeds were inoculated with the gav isolate of barley yellow dwarf virus ( bydv ) by schizaphis graminum ( rondani ) and the results revealed that 33 wheat seedlings did not produce the symptom or the symptom was very mild 通过花粉管通道法将pap基因导入小麦，收获了转基因小麦种子320粒，将其播种，返青后，直接用麦二叉蚜将大麦黄矮病毒( bydv ) gav株系接种到幼苗叶片上，观察发病情况。
