查询词典 mutant

To make comparison of adaptability of the plastid-less mutant and the wild type strain, we studied their growth characters under different culture conditions, found that the difference of their growth in a medium rich in organic substances are hardly detectable and that the loss of plastid exerts only a weak effect, if any, on the heterotrophic growth.

为比较完全失去质体结构的突变株和野生型的适应力，我们对二者在不同条件下的生长特性进行了研究，结果发现野生型与突变株的生长在有机质丰富的培养液中差别微弱，质体的丢失并不产生显著影响。

Pokeweed antiviral protein belongs to Ribosome-inactive Proteins . PAP has potent antiviral activity against many plant virus. pTI was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-, C-deleted) by PCR and then the two genes were cloned into expression vector.

美洲商陆抗病毒蛋白是一类能很好的抑制植物病毒的蛋白，很早就有报道低剂量的商陆叶片粗粉末就能明显的抑制TMV在菜豆叶片上局部枯斑的形成，PAP缓释剂也己用于病毒病的防治工作。

The total RNA was isolated from pokeweed leaves using the method of guanidine isothiocyante and used as template for amplification of the deleted mutant pokeweed antiviral protein gene by RT-PCR and then the amplified fragment was cloned into secreted expression pPIC9K vector to form pPIC9K-p, then the vector was transferred into Pachia pastoris GS115 strain.

从美洲商陆叶片中通过异硫氰酸胍法提取出了总RNA，经RT-PCR扩增出缺失突变型抗病毒蛋白PAP基因，将该基因克隆于分泌型真核表达载体pPIC9K，然后导入毕赤酵母菌株GS115细胞。

PAP-C23, amplified from mature pokeweed antiviral protein gene by PCR, was cloned into the expression vector PET101, and then the recombinant plasmid was transformed into Escherichia coli BL21(DE3). The recombinant mutant PAP was expressed high-levelly induced with IPTG.
