包尔在实验室所作的研究显示，野生燕麦燕麦的野草亲戚可以“攫取”抗大麦黄矮病毒的基因。 |
| 3. | Power ' s work , carried out in the laboratory , indicates that wild oats ? a weedy relative of cultivated oats ? can “ catch ” the genes conferring resistance to barley yellow dwarf virus
包尔在实验室所作的研究显示，野生燕麦（燕麦的野草亲戚）可以攫取抗大麦黄矮病毒的基因。 |
| 4. | Via investigation and analysis , it discussed relation between occurrence of wheat yellow dwarf and yield . morbidity and grades standard was determined as well as wheat dwarf economic threshold
摘要通过系统调查与分析，探索了小麦黄矮病的发生程度与产量的关系，确定了其发病程度与分级标准，研究出了小麦黄矮病的经济阈值。 |
| 5. | Power investigates gene flow in cultivated grain crops ? wheat , barley and oats ? engineered to contain genes that make the plants resistant to the barley yellow dwarf virus ( which damages some 100 grass species )
包尔正在调查小麦、大麦和燕麦等谷类作物的基因流通，它们都植入了抵抗大麦黄矮病毒的基因，此种病毒会侵犯约100种草类植物。 |
| 6. | Power investigates gene flow in cultivated grain crops wheat barley and oats engineered to contain genes that make the plants resistant to the barley yellow dwarf virus which damages some 100 grass species these gm grain crops could be on the market within the next decade
包尔正在调查小麦大麦和燕麦等谷类作物的基因流通，它们都植入了抵抗“大麦黄矮病毒”的基因，此种病毒会侵犯约100种草类植物。 |
| 7. | Barley yellow dwarf virus often leads to a serious loss in the yield of wheat . but at present , we have not find excellent genes resistant to bydv in wheat , so transferring the excellent genes from relatives to cultivars of wheat will be a good method
因此，植物耐盐、耐黄矮病、耐蚜虫等机理和相应耐性植物的培育，乃至相应耐性相天基因的分离与克隆及其基因工程育种的研究正在受到人们越来越多的关注。 |
| 8. | 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。 |
