Consequently an improved PAGE technology suitable for detecting results of breeds for resistant or sensitive species of powdery mildew in wheat was developed.
因此,我们研究出了一项利用聚丙烯酰胺凝胶电泳检测小麦白粉病抗、感特性的新技术,在工作中建立了一种适合于检测小麦基因组DNA结构差异的电泳方法。

The results suggested that the activities of these enzymes quickly enhanced at 1 d, 3 d, 5 d and 7 d after inoculation by injecting conidia of the false smut fungus at 7-10 d before heading in the resistant cultivars, but slower increase in the susceptible cultivars, and also showed that there was correlations between the cultivar resistance to the disease and the three enzymes.
结果表明,在抗病品种中苯丙氨酸解氨酶、过氧化物酶和多酚氧化酶3种酶活性接种后迅速提高,变化幅度较大;而感病品种的酶活性在接种后缓慢增加,变化幅度小。由此说明,这3种防御酶与水稻抗稻曲病有一定的关系。关键词水稻;稻曲病;防御酶

Lines transformed by particle bombardment have been discussed. The selectable marker bar gene cassette that integrated with the rice genome had multiple copies and showed complex segregation behavsensitive plants in their progenies. In five out of ten original transgenic lines, bar gene can be stably transmitted as a dominant gene to self-pollinated T2 progeny.
结果发现:作为筛选标记的bar基因表达盒在水稻基因组中多拷贝整合,遗传分离行为复杂,还出现了Basta抗感分离比在35∶1~144∶1之间的&假纯合体&,但50﹪转基因株系中(5/10)bar基因可作为一个显性基因按孟德尔方式稳定遗传至自交T2代。

Lines transformed by particle bombardment have been discussed. The selectable marker bar gene cassette that integrated with the rice genome had multiple copies and showed complex segregation behaviors including the presence of 'false homozygotes', with abnormal segregation ratios ranging from 35:1 to 144:1 (Basta-resistant: sensitive plants) in their progenies. In five out of ten original transgenic lines, bar gene can be stably transmitted as a dominant gene to self-pollinated T2 progeny.
结果发现:作为筛选标记的bar基因表达盒在水稻基因组中多拷贝整合,遗传分离行为复杂,还出现了Basta抗感分离比在35:1~144:1之间的&假纯合体&,但50%转基因株系中(5/10)bar 基因可作为一个显性基因按孟德尔方式稳定遗传至自交T2代。

For 15 years, as a hospital doctor in the rural town of Tugela Ferry, in the heart of South Africa's KwaZulu-Natal province, he had watched locals with extinguished immune systems die from infections like tuberculosis, unable to give them medicine that worked.
从医15年来,他曾亲眼目睹各种药物是如何在崩溃的免疫系统面前败下阵来,让肺结核之类的感染病轻易地致当地居民于死地。2005年开春之时,这种抗逆转录病毒药品也为一大批患者送去了生命的春天。
