玉米矮花叶病和玉米粗缩病是近10年来为害我国玉米生产的两种主要病毒病[1]。

Species in the genus Thinopyrum are important wild relatives for wheat improvement. They possess many desirable traits such as drought, cold and salt tolerance, long spikes and more florets, high protein concentration. It has also been found that some species are the source of resistance genes for rust and powdery mildew, and especially, the source of resistance to wheat streak mosaic virus and barley yellow dwarf virus .

偃麦草属植物是小麦遗传改良中的重要野生近缘种，蕴含抗寒、抗旱、耐盐碱及长穗多花、籽粒蛋白质含量高等优良性状，同时又是小麦锈病和白粉病的重要抗源，特别是在小麦条纹花叶病和大麦黄矮病等病毒病的抗病育种中发挥了重要作用。

This developed a new material for the wheat virus-resistance breeding.In order to breed maize dwarf mosaic disease梤esistance maize species, the PAP gene was introduced into maize inbred strains and hybrid strains mediated by pollen and particle bombardment,10 transgenic maize plants were achieved and the PAP gene was indeed integrated into the maize genome by analysis of molecular biotechnological methods. The PAP gene in one of the transgenic maize plants had been transcription and translated, the ability of the virus resistance is undergoing.

为了解决玉米矮花叶病害的防治问题，采用花粉介导法及基因枪法将PAP基因分别导入玉米的杂交种及自交系，获得了10株转基因玉米，PCR及Southern-blot检测结果表明PAP基因已经整合到了玉米基因组中，并且其中有一株PAP基因已经得到了表达，病毒抗性鉴定表明转基因玉米能明显推迟玉米矮花叶病害症状的表现。

Although the virus is similar with other isolates in other regions,which have white spot symptom,in morphology,range of host,symptom etc,but it is very different from others in size of virion,distribution in host cell,size of the genome,etc.So,we think that it isa new virus of penaeid shrimp.

虽然该病毒在形态、寄主范围、症状等方面与其它地区分离到的能产生白斑症状的对虾病毒相似，但它在粒体大小、在细胞内的分布、基因组的大小等方面与其它地区的病毒分离物差异很大，属不同种的病毒。

Newcastle disease is A violent contagion classified by OIE. Newcastle disease virus is a member of Rubulavirus, Paramyxovirinae, Paramyxoviridae, and a negative RNA virus which has vesica membrane.

新城疫病毒是副黏病毒科、副黏病毒亚科、腮腺炎病毒属的成员，为有囊膜的负链RNA病毒，可存在于病禽的所有组织器官、体液、分泌物和排泄物中。

Antibody responses to hepati tis C virus and its modes of transmission in dialysis patients. Nephron, 1991, 5 9: 2328 Pol S, Romeo R, Zins B et al. Hepa titis C virus RNA in anti-HCV p ositive hemodialyzed patients: significance and therapeutic implications.

本组资料中具有输血史的患者在HCV抗体阳性组中所占的比例明显大于在HCV抗体阴性组中所占的比例，似乎支持这一观点，但另一方面，仍有8例HCV抗体阳性患者未曾有过输血史，提示HD患者存在输血以外其它途径感染的可能［3］。

The good news is that a virus writer is confronted with the same theoretical limit as are anti-virus technologies.

好消息是，病毒作者和反病毒技术一样也遇到相同的理论限制。

You can do some assertiveness training.

你可以进行一些自信训练。
