查询词典 Galanthus

The sequence alignment suggests that the secondary structures of these proteins are very similar to that of the Galanthus nivalis lectin and that they also possess the same sugar-binding site found in the GNA.

为研究天麻抗真菌蛋白基因的表达调控方式，构建了五个GAFP-2基因启动子区和GUS基因融合的表达载体，并通过农杆菌介导的植物遗传转化方法导入烟草中。

An expression vector was constructed with a safe marker gene, 6-phosphomannose isomerase, and an insect-resistant gene, Galanthus nivalis agglutinin, was used in rice genetic transformation in the present study.

采用农杆菌介导法将来源于大肠杆菌的6-磷酸甘露糖异构酶安全选择标记基因和雪花莲凝集素抗虫基因构建于同一表达载体上进行遗传转化，获得带有安全标记基因的抗褐飞虱转基因植株。

A modified Galanthus nivalis agglutinin gene was introduced into the genome of main cultivar 'Ningqi No.1' of Lycium bararum in vitro with explants of leaf disks mediated by Agrobacterium tumefaciens. Several factors affecting transformation efficiencies were studied based on induction rate of resistant callus. An effective system for genetic transformation of Lycium bararum was set up, and 70 kanamycinresistant transformants were obtained.

为了解决枸杞蚜虫侵害的难题，以宁夏枸杞主栽品种&宁杞1号&叶片为外植体，通过农杆菌介导的转化方法，将改造后的雪花莲凝集素GNA基因转入枸杞，以抗性愈伤组织诱导率作为转化效率的指标，对影响转化效率的因素进行了研究，初步建立了转化频率较高的转化系统。

OBJECTIES:: We report our obserations after Galanthus nialis affinity purification of recombinant HI enelope proteins (CHO gp120/140/160) deried from subtypes B/A and using these purified proteins as antigens in ELISA assays (against subtype C induced antibodies).

实验对象：来自B/A亚型的重组HI包膜蛋白（CHO gp120/140/160）经GN亲合纯化后，然后在ELISA试验中将这些纯化的蛋白作为抗原。

Introducing into to wheat the gna gene that encodingsnowdrop lectin(Galanthus nivalis agglutinin;GNA),a toxic protein to Homoptera,or cryIA gene that encoding Bacillus thuringiensis insecticidal protein forLepidopteraby genetic transformation will produce new germplasm that maybe produce resistant to somekinds of pests.

利用转基因技术，将对同翅目昆虫具有抗性的雪花莲凝集素基因gna和对鳞翅目昆虫具有抗性的苏云金芽孢杆菌杀虫蛋白基因cryIA导入小麦，极有可能获得对某些害虫具有一定抗性的小麦新种质。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
