诱变的

This program is to explore the high tech and traditional breeding of a new variety of Porphyra haitanensis, in hope of its fast growth, high quality and endurance of high temperature. This variety has been growing various areas, and it shows that is yield increases above to 26 %-30%, and the contentof three main pigments (phycoerythrin, phycocyanin and chlorophyll a) increases 10 % at least. And it has stronger capability of resisting disease and fester.

突变体MLA-1与原亲本的SSR多态性比较研究的结果表明，MLA-1和原亲本"美香占"在DNA水平上表现出明显的不同，选用180对微卫星引物对MLA-1和原亲本进行SSR分析，有22.8%的扩增产物在两个材料间表现出了多态性，说明空间诱变后发生多位点的突变。

The results showed that all contents were lower in male sterilie anthers than in fertilisable ones.With anther developing,the contents of soluble starch,protein and free proline increased obviously in male fertilizable anthers,but not in sterile ones.

结果表明：太空诱变处理玉米核不育材料的可育株花药中的可溶性糖、淀粉、蛋白质以及游离脯氨酸含量均高于不育株花药的，且可育株花药中的可溶性淀粉、蛋白质和脯氨酸含量都随着花药的发育逐渐累积，在不育株花药中这些指标的变化不明显。

The traditional way for selecting strains is wide way, the modern microbiologic technology taking the gene engineering as center is also applied for strains breeding,and it becomes the main way gradually.

传统的诱变育种是最广泛的选育方法，以基因工程为核心的现代生物技术也应用于农用抗生素产生菌的菌种选育中，并逐渐成为农用抗生素菌种选育的主导技术。

Through the research we have established in planta transformation system, mutangenesis and screening system for salt sensitive mutants, and constructed a cDNA library under salt stress and cloned a serious of salt-tolerance related genes which had been confirmed the function by overexpression in Arabidopsis or antisense expression in Thellungiella. We also compared different mapping strategy through the analysis of the genetic polymorphism between ecotypes, and establishing mapping population for physical mapping.

建立了小盐芥的转化体系与盐敏感突变体诱变与筛选体系，构建了盐胁迫下的cDNA文库并克隆了一批耐盐相关基因，并通过模式植物拟南芥转化与小盐芥的基因反义表达证实其功能，通过不同生态型小盐芥的遗传多样性分析探讨了基因组作图的策略，建立了作图群体并开始进行物理图谱构建。

A it is predominantly derived from the initial variety or from a variety which itself was predominantly derived from the initial variety, while retaining the expression of essential characteristics that result from the genotype or combination of genotypes of the initial variety; an essentially derived variety may have been obtained by the selection of a natural or induced mutant or of a somaclonal variant, by the selection of a variant individual from plants of the initial variety, by backcrossing, by a transformation by genetic engineering, or by any other similar method

一个品种主要由原始品种演化而来，或主要由原始品种的实质性派生品种演化而来，同时保留了来自原始品种基因型或基因型组合的基本特征的表达；一个实质性派生品种可能通过选择自然变异或诱变或体细胞无性变异、原始品种植株的个体变异的选择、回交、基因工程的改造或任何其它类似方法而获得。

Taking Eremothecium ashbyii (abbreviated as Eaw95. 1) as the original strain, after Υ-ray mutation, tubercidin and 8--azaguaniae (8--AG) resistant tests, a strain labeled as T〓 capable of overproducing riboflavin was obtained and its genetic stability was analyzed. Compared with Eaw95. 1, the riboflavin productivity was improved about 40% by flask--shaking tests.

以Eremothecium ashbyii为出发菌（间称Eaw95.1），通过Υ-射线诱变，杀结核菌素和8-氮杂鸟嘌呤等结构类似物的的抗性筛选，获得了一株核黄素高产菌T〓，并对菌株的遗传稳定性进行了研究，获得了较好的效果，与出发菌株相比，核黄素的摇瓶发酵产量提高了近40％。
