- Expression Behavior of Bt Toxin Gene in TransgenicTobaccos. 转基因烟草中Bt毒蛋白基因的表达行为。
- An antibody formed in response to and capable of neutralizing a specific toxin of biological origin. 抗毒素可抵制并能中和一种由生物引起的特殊毒素的抗体
- This major scientific advance was followed in 1987 by the production of tomato plants that contained the toxin gene. 主要的科研进展是在1987年培养出含有毒素基因的西红柿植株。
- The study is focused on the molecular epidemiology of Aeromonas hydrophila Aerolysin-like toxin gene and its application in aquiculture. 本项目对水产养殖危害严重的致病菌嗜水气单胞菌气溶素类毒素基因流行病学的理论和应用进行了较为全面的研究。
- The toxin gene in different strains of B. thuringiensis can affect different mixes of insects, so seed makers can select the version that seems best suited to a particular crop. 例如说，“环保科学家协会”的梅隆指出，耐盐稻米一旦落到湿地上，可能会像野草般蔓延，破坏脆弱的湿地生态系。
- Meanwhile, it was noticed that toxicity of Bt-BS2 against susceptible mosquito larvae was higherthan that ofBt-BSI and this might be explained by the inserted direction of the binary toxin gene perhaps influencing its expression in the recipient strain. 此外，Bt-BS2的杀蚊毒力高于Bt-BS1，Bt-BS1和Bt-BS2对蚊幼虫毒力的不同可能是由于重组质粒上外源片段的插入方向影响二元毒素基因在受体菌中的表达水平的缘故。
- an antibody that can neutralize a specific toxin. 能中和一种特殊毒素的抗体。
- The Toxin gene and Bt gene were first transformed into Acer negundo by Agrobacterium-mediated method and needle-sticking method. Transgenic calli and transgenic plants were obtained by PCR and PCR-Southern hybridization analysis. 通过农杆菌介导法和针刺法,首次将蜘蛛神经毒蛋白杀虫肽基因Toxin和Bt基因导入复叶槭,经分子生物学检测,获得了复叶槭抗虫转基因愈伤组织和转基因植株。

- GE can involve the exchange of genes between vastly different species, e.g. putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes. 它可在有巨大差异的物种之间进行基因交换。比如，将蝎子毒素基因注入玉米，或者将鱼防冻基因注入西红柿。
- Further study showed that clostridial toxin genes were detected in both HBS and control animals. A. fumigatus could only be detected in all HBS cow but not in the control. 经进一步研究表明,在HBS病牛和对照奶牛中都检测到梭菌毒素基因,而烟曲霉菌只在患病奶牛中检测到,对照牛则呈阴性。
