突变的

When grown in the light and with nutrition as the limiting factor, the wild type was less influenced due to its capability of photosynthesis and quickly became predominant over the mutant that has no photosynthetic apparatus. However, when grown heterotrophically in the dark, the mutant remained less competitive than the wild type, showing that the euglenoid proplastids play a role in competition.

在光照情况下，当营养物质成为限制因子时，由于具有光合能力野生型生长受影响较小，在与没有光合器的突变株的竞争中很快地显示出优势；在黑暗中二者均只能以异养方式生长，但突变株仍然处于竞争弱势，显示原质体结构对于生存竞争的作用。

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Due to the inveracity of statistical probability with little sample of disasters, the mutation progression was used to calculate the probability instead of the statistical probability and fuzzy degree instead of brittle events' value.

鉴于小样本灾害事件统计概率的不准确性，用突变级数法计算的脆性因子突变概率代替脆性风险熵计算中的统计概率，模糊数代替脆性事件结果价值。

To construct the combined site_directed random mutation library of recombinant human Lymphotoxin for in vitro molecular evolution study, and to study the structure and function relationship.

应用含随机核苷酸序列的引物，通过OverlapPCR的方法分别对rhLT的 4 6、10 6和 130位氨基酸进行定点随机突变，获得各单点随机突变体库。

In this study, a stress induction expression promoter of monocotyledon (P-WCS120) was amplified from wheat genome. The result of sequencing displayed a base substitution mutant of 1 bp and an insertion mutant of 21 bps. This sequence was registered at GENEBANK as a new found sequence, because 3% of the sequence was found to be non-homologous with the original sequence.

本研究从小麦基因组扩增单子叶植物逆境诱导表达启动子P-WCS120，测序证明包括1个碱基的替代突变和21个碱基的插入突变，与原序列有3%的非同源性，被GENBANK认定为新发现序列，现已登记注册。
