对抗病

This paper introduces a few important pest resistance gene as well as its important role in agricultural production.

本文主要介绍了几种重要的抗病害虫的基因以及它对我们农业生产的重要作用。

In plants , NO has recently been demonstrated to be involved in the regulation of growth and development in the response to abiotic and biotic stresses and it is a key signal messenger in disease resistance in plants. More important , it has been found that NOs function in plant is similar to the traditional phytohormone , so it is forecasted to be a new type of hormone in plant.

近年来的研究发现，它不仅在血管松弛、神经传导以及先天性免疫反应等动物生理代谢过程中是一种关键的第二信使，而且在植物中也起着非常重要的作用，是植物生长和发育的调节分子，能够对生物性和非生物性的胁迫作出反应，并且在植物体的抗病防御反应中也是一种重要的信号物质；更重要的是，近年来发现NO与各种植物激素的功能都有着重叠，因此有人预测NO可能是植物体内的一种新型激素。

The results indicated that 3 chemicals could greatly enhance resistance of potato tuber to early blight at low concentrations.Protection rates induced by phenol(1 mmol/L),benzoic acid(0.01 mmol/L),and paraaminobenzoic acid(5 mmol/L) were 43.21%,40.72%,and 28.75%,respectively.

结果表明，供试的3种化合物均在较低浓度下具有较强的诱导抗病作用，苯酚、苯甲酸和对氨基苯甲酸分别在1，0.01和5 mmol/L时诱导的保护率最高，分别达到43.21%，40.72%和28.75%，均与对照差异极显著。

Positive significant correlation between three infection indexes and SDD, and negative insignificant correlation between infection indexes and LIP were found. Fifteen sugarcane varieties could be divided into 6 groups on the basis of the distance more than 1.0. It resulted most ot tested sugarcane varieties had similar smut resistance. It suggested that smut race 1 and race 2 were included in inocula and the condition for Ustilago scitaminea infection was suitable in the crop season by setting up the standard varieties of NCo310, F134, NCo376 and Ya71-374 for smut identification. In addition, the results of sugarcane varieties resistant to smut race 1 and race2 were known by only a simple field trial.

结果显示：9个引进甘蔗品种中，ROC26属于感病品种，其余属于抗病或高抗品种；3个病情指数和持续发病期的两两相关均为显著正相关，潜伏侵染期与这些参数的相关为负相关，但未达到显著水平；在类间距离大于1.0的条件下，可将15个品种聚为6类，进一步明确了各品种抗黑穗病性的相似程度；抗性鉴定标准对照种NCo310、F134、NCo376和Ya71-374的应用，明确了接种源为小种1和小种2，通过一次接种试验，明确了供试品种对2个小种的抗性水平，标准对照种的抗性表现，还说明了本生长季发病条件基本是适宜的。

By inoculating leaves in vitro, the identification of disease resistance showed that GO transgenic plants had resistance to Rhizoctonia solani.

抗病性鉴定结果显示，转GO基因植株对水稻纹枯病具有不同程度的抗性。

The results showed that the 20 cultivars could be clustered into 4 groups based on their resistances to C.truncatum, among which ProINTA Patricia and Victoria SPI were the best, but Defi, Lobo, Salado, Xinjiang large-leaf and Travois were the weakest, while the other 13 cultivars had medium resistance to C.truncatum.

结果表明，不同品种抗苜蓿炭疽病能力的强弱不同，通过聚类分析将供试品种划分为4个类群，以ProINTA Patricia和Victoria SPI对苜蓿炭疽病的抗性最好，Defi德福、Lobo路宝、Salado萨兰多、新疆大叶苜蓿和Travois的抗病性最差，其他品种呈中等抗性。

The researches of snakehead immune system are essential for understanding immune mechanism and antiviral drug discovery in fish.

乌鳢免疫相关基因的研究工作对了解鱼类免疫机制以及鱼类抗病药物的开发具有重要的理论指导意义。

Spore spray and hype double holes injection methods are used to evaluation some snap bean germplasms resistance to anthranthranose and Fusarium root rot during seedling.7 varities are high resistence to anthranthranose and 1 variety is high resistanee to Fusarium root rot.

采有喷雾接种法和下胚轴双孔注射法分别对部分菜豆种质资源进行炭疽病和枯萎病的抗性的苗期鉴定，从所供试的材料中筛选出高抗菜豆炭疽病材料7份，高抗菜豆枯萎病材料1份，为抗病育种奠定了基础。

Massage is good for common cold, it can not only strengthen the immunity and the physical function of the body, make the body anti disease itself, resist the infection of the virus and the bacteric, but also ease the uncomfortable symptom, such as headache, and snuffle, so to cure the disease.

按摩对治疗感冒有较好的疗效，不但能增强机体的免疫功能，增强机体的各项生理功能，使机体发挥其自身的抗病能力，抵抗病毒和细菌的感染，而且能直接缓解或减轻头痛、鼻塞等不适的症状，以达到治病的目的。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
