2与水稻褐飞虱中肠刷状缘膜囊泡(BBMV)相结合的活性短肽筛选显示文摘参照鳞翅目和双翅目昆虫中肠刷状缘膜囊泡(BBMV)的提取方法,成功提取了水稻褐飞虱中肠BBMV蛋白,利用噬菌体短肽文库展示技术,筛选到2个能够与水稻褐飞虱中肠BBMV结合的短肽P1Z和P2Z.以EGFP蛋白为标签通过Pull down和Western blot方法对短肽P1Z、P2Z与褐飞虱中肠BBMV的结合活性进行了验证.结果表明,利用噬菌体短肽文库展示技术,以褐飞虱中肠BBMV作为底物,经过3轮淘洗筛选到的短肽蛋白与褐飞虱中肠BBMV上的潜在受体具有较强的结合能力.通过对短肽结构域的分析发现,短肽结构α两亲区与β两亲区的分布情况是影响短肽与褐飞虱中肠BBMV结合的一个潜在因素.本研究成功筛选并验证了能够与褐飞虱中肠BBMV结合的短肽.邵恩斯 庄浩瀚 关雄 2013应用与环境生物学报2013,19,4:1
3Toxicity and binding analyses of Bacillus thuringiensis toxin Vip3A in Cry1Ac-resistant and-susceptible strains of Helicoverpa armigera(Hübner)显示文摘The Bacillus thuringiensis vegetative insecticidal protein, Vip3 A, represents a new family of Bt toxin and is currently applied to commercial transgenic cotton. To determine whether the Cry1Ac-resistant Helicoverpa armigera is cross-resistant to Vip3 Aa protein, insecticidal activities, proteolytic activations and binding properties of Vip3 Aa toxin were investigated using Cry1Ac-susceptible(96S) and Cry1Ac-resistant H. armigera strain(Cry1Ac-R). The toxicity of Vip3 Aa in Cry1Ac-R slightly reduced compared with 96 S, the resistance ratio was only 1.7-fold. The digestion rate of full-length Vip3 Aa by gut juice extracts from 96 S was little faster than that from Cry1Ac-R. Surface plasmon resonance(SPR) showed there was no significant difference between the binding affinity of Vip3 Aa and BBMVs between 96 S and Cry1Ac-R strains, and there was no significant competitive binding between Vip3 Aa and Cry1 Ac in susceptible or resistant strains. So there had little cross-resistance between Vip3 Aa and Cry1 Ac,Vip3A+Cry proteins maybe the suitable pyramid strategy to control H. armigera in China in the future.ZHANG Qian CHEN Li-zhen LU Qiong ZHANG Yan LIANG Ge-mei 2015Journal of Integrative Agriculture2015,14,2:0
