杂交

So we can infer that hybridization played a key role in population astatic differentiation and loss of genetic diversity.

表明杂交可能是造成群体无定向分化及遗传多样性丧失的主要机制之一。

Genes encoding Drought-Responsive-Element Binding proteins were cloned from Triticum aestivum and Atriplex hortensis. TaDREB1 and AhDREB1 can specifically bind the DRE elements in the promoters and thus activate the transcription of downstream genes in yeast cells as well as transgenic Arabidopsis and transgenic tobacco plants.

克隆了小麦和山菠菜转录因子TaDREB1和AhDREB1基因，它们都编码DRE（Dehydration-Responsive-Element）结合蛋白，在酵母单杂交系统、转基因拟南芥和转基因烟草中都能特异结合DRE元件并激活下游报告基因的表达。

Love was the maternal donor of the polyploid Elymus; the "Y" genome existed in the StY-genome Elymus may be differentiated from the St genome, i.e., the autopolyploid StSt-genome species probably experienced genomic differentiation within a species after autopolyploidy, leading to the significant genomic change and resulting the StY-genome allotetraploids; the StY genome species distributed in the Central Asia with a high level of genetic diversity radiated to the Western and Eastern Asia, under the environmental selection and other factors, and only a few species spread to the western Asia and most species have remained in the Central and eastern Asia.

3分子证据表明在StY基因组的物种之间有明显的地理分化，中亚可能是StY基因组披碱草属植物的分化中心，并在此基础上，StY基因组的披碱草属植物向东亚和西亚进行了快速的辐射，形成了现代StY基因组物种的分布格局；多次杂交、迁移和分化是StY基因组的披碱草属植物进化的主要动力。(4)拟鹅观草属物种可能是所有披碱草属植物的母本供体。

Results: Hybridization signals were clear by autoradiograph in different density.

结果 ：放射自显影显示出清晰的各具不同密度的与预期产物相同大小的杂交信号。

Via these formulas, the numerical solutions are incorporated with the analytical solution on the auxiliary circle.

在此基础上进一步建立了杂交元算式，它能保证在圆形人工边界上数值解和解析解两种场函数及其导数的相容性。

E. SC-P34M54_(378), SC-P32M59_(147) and SC-P36M53_(99).3. The genetic relationship between the 3 SCAR markers and SSR marker (Xwmc441) were test with 208 segregating F_2 plants derived from a cross between Avocet S and the NIL YrSp/6xAvocet S.

用208株Avocet S和YrSp/6 x Avocet S杂交制备的F_2代分离群体，对获得的3个SCAR标记和YrSp的SSR标记Xwmc441之间的遗传关系进行了检验。

Genetic linkage was tested on 121 segreg ating F2 plants derived from a cross between Avocet S and Yr5 /6 Avocet S.It was showed that the polymorphic DNA fragment S1320 207 was completely linked to Yr5 gene,and S1348 363 closely linked to Yr5 gene.

用121株Avocet S和 Yr5 /6 Avocet S杂交制备的 F2代分离群体进一步进行的遗传连锁性检测表明，多态性DNA片段 S1320 207 和S1348 363 分别与 Yr5 基因完全连锁和紧密连锁。
