| 1 | Ubi1 intron-mediated enhancement of the expression of Bt cry1Ah gene in transgenic maize (Zea mays L.)显示文摘The cry1Ah gene was one of novel insecticidal genes cloned from Bacillus thuringiensis isolate BT8. Two plant expression vectors containing cry1Ah gene were constructed. The first intron of maize ubiqutin1 gene was inserted between the maize Ubiquitin promoter and cry1Ah gene in one of the plant expressing vectors (pUUOAH). The two vectors were introduced into maize immature embryonic calli by microprojectile bombardment, and the reproductively plants were acquired. PCR and Southern blot analysis showed that foreign genes had been integrated into maize genome and inherited to the next generation stably. The ELISA assay to T1 and T2 generation plants showed that the expression of Cry1Ah protein in the construct containing the ubi1 intron (pUUOAH) was 20% higher than that of the intronless construct (pUOAH). Bioassay results showed that the transgenic maize harboring cry1Ah gene had high resistance to the Asian corn borers and the insecticidal activity of the transgenic maize containing the ubi1 intron was higher than that of the intronless construct. These results indicated that the maize ubi1 intron can enhance the expression of the Bt cry1Ah gene in transgenic maize | WANG YueBing LANG Zhihong ZHANG Jie HE KangLai SONG FuPing HUANG DaFang | 2008 | Chinese Science Bulletin2008，53，20： | 15 |
| 2 | Transgenic tobacco plants expressing synthetic Cry1Ac and Cry1Ie genes are more toxic to cotton bollworm than those containing one gene显示文摘Transgenic tobacco plants carrying Cry1Ac, Cry1Ie or both genes were obtained. In the leaves of transgenic plants carrying both genes, the contents of Cry1Ac and Cry1Ie proteins were 0.173% and 0.131% of the total proteins, respectively. Cry1Ac protein content was 0.182% and Cry1Ie protein con- tent was 0.124% of the total proteins in the leaves of transgenic plants containing only one Bt gene. Fresh leaves of transgenic tobacco and wild-type plants were used for the insect bioassay against wild-type and Cry1Ac-resistant cotton bollworm (Helicoverpa armigera). The bioassay results showed that transgenic plants carrying both genes were significantly more toxic to wild-type and Cry1Ac-resistant cotton bollworm than those carrying Cry1Ac or Cry1Ie alone. This study indicates that the higher toxicity of transgenic tobacco plants carrying both genes is caused by the cooperative function of both Bt proteins, thus providing a potential way to delay the development of insect resis- tance to transgenic crops. | LIAN Yun JIA ZhiWei HE KangLai LIU Yundun SONG FuPing WANG BaoMin WANG GuoYing | 2008 | Chinese Science Bulletin2008，53，9： | 7 |
| 3 | Evaluation of spatial and temporal patterns of insect damage and aflatoxin level in the pre-harvest corn fields to improve management tactics显示文摘在与有一致基因背景的植物的一个玉米领域里的黄麴毒素污染的关系的昆虫损坏的空间、时间的模式很好没被理解。在昆虫损坏和黄麴毒素在的空间模式的以前的考试以后预先收获玉米地,我们进一步与二采样检验了喂圆块、喂核的昆虫损坏,和黄麴毒素水平的空间、时间的模式在在 2008 和 2009 预先收获。由每 ear/kernel-feeding 昆虫的喂的损坏(即,丝绸 / 圆块上的玉米一种有害幼虫 / 秋天粟蚕损坏,和玉米核由的褪色坏透臭虫) 并且玉米象鼻虫人口用五只耳朵在每个格子点被估计。采样数据在两年里处于昆虫损坏和黄麴毒素污染显示出域边效果。玉米象鼻虫比任何一个玉米一种有害幼虫更经常向聚集的分布趋于或坏透两年里的臭虫损坏。为黄麴毒素水平检测聚集的分发的频率是昆虫损坏评价的不到任何东西。坏透臭虫损坏和玉米象鼻虫数字更仔细比是玉米一种有害幼虫的与黄麴毒素水平被联系损坏。另外,空间时间的协会(χ
) 的索引证明玉米象鼻虫的数字被联系在之间第一(4 个星期预先收获) 并且秒(1 个星期预先收获) 所有地上的两年里的采样。相反,在来自 Belflower 农场上的地的第一和第二采样之间的玉米一种有害幼虫损坏,和黄麴毒素水平和玉米一种有害幼虫在 Lang 农场上从这块地损坏在 2009 被分裂。 | Xinzhi Ni Jeffrey P. Wilson Michael D. Toews G.
