核菌

Objective To observe the survival of Neisseria gonorrhoeae in the presence of karyote and in vitro.

目的 观察不同浓度的淋球菌在有核细胞内外和体外的存活状况。

When Shigella flexneri 2a 2457T is cultured at 30℃, it's phenotypically avirulent; when grown at 37℃, its virulence improves greately. There is clear evidence that the temperature-dependent expression of the virulence genes is controlled by H-NS protein.

痢疾杆菌在30℃时不具有侵袭力，37℃时毒力明显增强，已有的研究表明这种依赖于温度的毒力基因的表达受H-NS蛋白的调控。H-NS是一种重要的类核相关蛋白，在革兰氏阴性菌中普遍存在，能够调控大量基因的表达。

Objective. To determine if viral vectors carrying the gene for brain-derived neurotrophic factor could be used to promote an axonal regenerative response in rubrospinal neurons after an acute cervical spinal cord injury.

目标：本研究在于确定病毒带菌体存在着一种大脑源性神经营养因子的基因，这种基因可以在急性颈髓脊索损伤所致病例中引发红核脊索神经元的轴性再生反应。

Objectie. To determine if iral ectors carrying the gene for brain-deried neurotrophic factor could be used to promote an axonal regeneratie response in rubrospinal neurons after an acute cerical spinal cord injury.

目标：本研究在于确定病毒带菌体存在着一种大脑源性神经营养因子的基因，这种基因可以在急性颈髓脊索损伤所致病例中引发红核脊索神经元的轴性再生反应。

Seed contaminated with sclerotia is another method of introducing the fungus into clean fields.

种子污染是另外一种传播核盘菌的途径。

What is the origin of sclerotia in a field? There are four primary methods that fields are infested with sclerotia.

那么核盘菌最初在田块中是怎样产生的呢？

Sanitation practices such as with vegetable production, and clean seed programs to keep sclerotia out of seed lots are also useful practices in some crop production systems.

在某些作物的生产体系中，与蔬菜混作、调整种子的消毒程序等卫生实践都能使种子免受核盘菌的浸染。

Dual gene expression in leaves and petals at right time enhanced the distinction of resistance to Sclerotinia in rapeseed.

抗病双基因在叶片和花瓣发育的特定时期表达不仅提高了油菜对核盘菌侵染的针对性，还可能减轻转基因植株的能源消耗和生理扰乱。

Both Sclerotinia resistance and oxalic acid tolerance were significantly increased in senescence leaves of T1 lines.

转基因植株叶片尤其是衰老叶片对核盘菌的抗性及对草酸毒素的耐性均得到了增强。

A primary crop where myceliogenic germination plays a major role in the disease cycle is in Sclerotinia wilt of sunflower.

在向日葵核盘菌萎焉病的疾病周期中菌丝体遗传扮演着重要的角色。

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。
