In this research , by using of genomic in situ hybridization , random amplified polymorphism DNA technology and three specific SCAR molecular markers, the author analyzed wheat hybrid generations carrying the desired genes that were resistant to take-all, BYDV and/or powdery mildew, and developed some alien chromosome addition and translocation lines that were important in breeding practice, and some specific molecular markers that could be applied in marker-assisted selection.

本研究运用GISH、RAPD和SCAR分析方法，对抗全蚀病、黄矮病和兼抗黄矮病白粉病的小麦杂交后代材料进行分析，获得了一些对育种实践有重要意义的易位系、异附加系材料和几个可用于辅助育种的特异性分子标记。

It is a real time technology for the monitoring of dynamic progress of reactions, determination of kinetic constants, analyses of label-free and unpurified biological samples with very high sensibility and non-background interference.

它既可实时监测反应的动态过程、测定动力学常数，又能直接分析未经标记和纯化的生物样品，具有很高的灵敏度，且没有背景干扰。

Results: At 3, 7 days post-grafting, SC survived in the lesioned area, hippocampus and ventriculus lateralis. At 14 days post-grafting, SC were migrating along ependyma, meninges and blood vessels. In the area of corpus callosum, SC were arranged like chains. At 60 days post-grafting, the number of SC was decreased and the fluorescent mark of SC was weakened. At 90 days post-grafting, the survival cells were few.

结果：3天、7天时移植的雪旺细胞大量存活于损伤区、海马、侧脑室的脉络丛组织中。14天后可观察到细胞沿软脑膜、室管膜、血管周间隙迁移，并在胼胝体部位排列成索条状。60天时雪旺细胞的标记荧光减弱，细胞密度减少。90天时已观察不到荧光。

Therefore, we can use the AC type of Tf locus and the AA type in prt 1 as the deers marker to make the breeding of Gansu wapiti.

可应用Tf的AC型和Prt1的AA型标记甘肃马鹿的品种特征。

The clustering analysis classified the 24 cultivars into 2 groups and 5 subgroups, which respectively corresponded to indica-japonica differentiation and known rice heterotic groups based on pedigree information and blast reaction.

聚类分析将供试品种划分为籼粳差异明显的2个类群和分群结果与其系谱关系及抗性基本吻合的5个亚群，表明候选抗病基因标记可用于水稻品种的遗传关系、水稻病害控制和抗病育种方面研究。

Our molecular phylogenetic trees constructed by UPMGA and NJ methods were in general consistent with that based on biochemical,immunogenetic and cellular genetic markers except for differences in some populations.It was inferred from this study that all pig populations examined could be temporary classified into one breed,however,the population genetic character of Taihe Guanchao and Wanan Spotted pig populations should be further evaluated.

各类群的UPMGA和NJ聚类分析结果与采用生化、免疫和细胞遗传标记分析的结论不尽相同，在此基础上，结合现行分类方法，认为各受试猪群可暂时归并为赣中南花猪类型，但对泰和冠朝猪和万安花猪的品种归属性应作进一步分析。

In this context the wild mango germplasm at Lapuo County, Guangxi, China were studied by using their biological characteristics and the amplified fragments length polymorphism molecular marker. These wild mangoes were found morphologically similar to Mangifera indica; and the AFLP markers showed that at the similarity coefficient of 0.63, 92 mangoes including cultivars, Mangifera sylvatica Roxb., wild mangoes, Mangifera. Siamensis Warbg. were divided into 14 groups and that the wild mangoes at Lapuo were close to M. sylvatica Roxb. and M. siamensis Warbg., but remained to fall in the middle of the cultivars and could not be separated from them.

结果表明：那坡县野生芒果在形态学上与普通芒果较为相似；AFLP标记显示，包括部分栽培品种、林生芒果、广西百色那坡县野生芒果、泰国芒果等在内的92份芒果种质在相似系数0.63的水平上可分为14组，广西百色那坡县野生芒果虽然与林生芒果、泰国野生芒果等芒果属其它种较为接近，但仍处于栽培芒果的中间，不能与栽培芒果分开。

Fluorophore-assisted carbohydrate electrophoresis was used to analyse pectic oligosaccharides. The influence of different factors on the separation of oligosaccharides by FACE was investigated.

荧光辅助糖电泳是首先用荧光衍生化试剂对糖类分子的还原端进行衍生化标记，然后在一定浓度的聚丙烯酰胺凝胶上进行分离的分析方法，可同时分析中性糖与酸性糖。

BACKGROUND: At present, studies show that a kind of stem cell community which in many kinds of organizations can differentiate into tissue cells of different embryonic layers; but those are different from embryonic stem cells, embryonic stem cell will lose the part differentiation potential gradually during the development of pregnancy, and will present some special phenotypes or the molecular markers, as CD105 and so on, will call it postembryonic pluripotent stem cells.

背景：目前研究认为在胚胎发育后的多种组织中存在一类干细胞群体，可分化为不同胚层的组织细胞；但又不同于胚胎干细胞，随着妊娠期间胚胎的发育胚胎干细胞会逐渐失去部分分化潜能，会出现一些特殊表型或分子标记，如CD105，称其为胚胎后亚全能干细胞。

XML stands for E x tensible M arkup L anguage, it is a markup language used to structure data logically using tags that look very similar to HTML.

的XML 段由可扩展 M arkup 蜇 anguage站，它是一种标记语言，用于数据的逻辑结构的使用标签，看起来非常类似于HTML格式。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
