We reviewed the advances on the rice transgenic study including applications of transformation , applications of transgenic technology , and the inheritance and expression of exogenous genes in transgenic off - springs 综述了水稻基因转化的方法、转基因技术在水稻上的应用及外源基因在转基因后代中的遗传表达的研究进展。
The first part were introduction and background knowledge introduction . the seconded part studied rules about yenetic technology invention themes ' s exclusion mainly . the third part studied genetic technology ' s patentability 第三部分研究了基因技术的专利性，对基因技术不同于一般技术方案的专利性的特殊之处进行了分析。
To proveide the sword of genetic technology with a sheath of ethics , it is necessary to carry out an intensive ethical evaluation of genetic technology research , providing guidance and requirement for its application 要对基因技术之剑配上伦理之鞘，必须对基因研究和技术应用进行伦理思考和评判，发挥伦理评判对基因技术应用的引导和规范作用。
In gene technology , there are some other problems of whether gene diagnosis are confidential , how to abort fetus with genetic diseases , and whether gene treatment results in virus infection and activates protocarcinogenic gene 基因技术中基因诊断存在诊断是否保密、有遗传疾病的胎儿如何进行人工流产；基因治疗存在感染病毒和激活原癌基因问题。
In the fourth part , the paternity test is discussed . as a important method to know the real relation between the parents and child , paternity test is accurate enough , especially dna - test 作为父母子女自然血缘关系确定的科学方法，亲子鉴定技术随着基因技术的突飞猛进而迅猛发展，要求以亲子鉴定确定血缘关系的人也越来越多，但我国尚未制定相关法律。
With the development of in vitro culture and shoot regeneration from leaves , the method of agrobacterium - mediated transformation through leaf discs was widely adopted , and genes of interest have been transformed into strawberries 摘要随着植物离体再生技术的日益成熟和多种外源目的基因的分离与克隆，转基因技术以目的性强、周期短等优点成为草莓品种改良的重要途径。
This paper reviewed the application of transgenic technique to tomatoes , introduced transgenic tomatoes with characters of delayed fruit and leaf senescence , disease and insect resistance , herbicide resistance , adversity resistan ce and good fruit quality 综述了转基因技术在培育延熟番茄、抗病虫番茄、抗除草剂番茄、抗逆番茄、改进番茄品质和延缓叶衰老番茄等方面的研究进展。
