单基因的

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。

Single blastomere PCR is stable and reliable,and it can be used for preimplantation genetic diagnosis.

目的建立单卵裂球PCR技术，为开展单基因病的着床前遗传学诊断奠定基础。

For example, neural tube defects （NTDs--anencephaly, spina bifida, encephalocele, myelomeningocele） usually have multifactorial causes, although they also have many specific known single-gene, chromosomal, and environmental causes.

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

例如神经管缺陷（NTD，包括无脑，脊柱裂，脑膨出，脊髓脊膜膨出）通常有多基因造成，虽然也有许多已知的单基因，染色体和环境原因。

Genetic analysis with reciprocal crosses between gls and Kas plants indicated that gls possesses a recessive mutation in a single nucleotide locus.

遗传分析表明：gls突变体为单基因隐性突变；初步定位结果表明，GLS基因位于第四条染色体短臂上靠近0端的16万碱基附近区域。

Monogenic dwarf mutants 91G318,91D27 and 93-597 carried 1 pair of new recessive dwarf genes respectively.

单基因突变品系91G318、91冬27和93-597，各自携带1对新的隐性矮秆基因。

It is indicated that the involved species of this subfamily clustered into two clades: the first clade includes those of the genus Neptis, Phaedyma, Pantoporia and Lintinga; the second one includes those of the genus Parthenos, Moduza, Limenitis, Athyma, Lexias and Euthalia. The genus Limenitis is suggested to be monophyletic; and the genera Euthalia and Lexias proved to be sister to each other and form a monophyletic group. The genus Litinga appears to be more closely related to Neptini than to Limenitini.

基于Cytb基因的线蛱蝶亚科系统发育分析结果表明，所有线蛱蝶亚科聚为两大枝：第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属；第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属；其中线蛱蝶属非单系群，翠蛱蝶属和律蛱蝶属则为单系发生，并构成姐妹群；缕蛱蝶属与环蛱蝶族亲缘关系较近。

Objective To investigate the interaction between 5-HT2A receptor gene and MAOA gene in unipolar depressive patients.

目的 探讨单相抑郁症病因中5-HT2A受体基因与MAOA型基因的相互影响。

PCR , Southern blotting and selection on kanamycin medium indicated that BoCAL gene had single-sited integrated into cauliflower and conformed to the segregation of single-dominant gene by the law of Mendelian Inheitance.

PCR、Southern杂交和抗卡那霉素筛选表明，外源BoCAL基因已经转入受体植物并且是单位点插入，并且符合孟德尔单显性基因的遗传。

After the NK gene from recombinant plasmid pUC19-NK was cloned on expression vector pBV220, it was transformed into host cell E. coli HB101. Recombinant plasmid pBV220-NK was extracted for identifying by analysis of restriction enzymes, PCR and sequencing. Studies on recombinant strain's growth and expression showed that heterogene have no distinct effect on host cell. The recombinant plasmid have excellent segregational stability but low structural stability. The results of kinetics of pBV220-NK expression in E.

将重组质粒pUC19-NK上的纳豆激酶基因成功克隆到表达载体pBV220上，并将之转入大肠杆菌HB101中，得到转纳豆激酶基因工程菌，提取重组质粒经单酶切、双酶切及PCR分析验证后，对重组菌的生长及表达进行一系列研究，结果表明：外源纳豆激酶基因的导入对宿主的生长没有明显的影响：重组质粒的稳定性实验表明：该质粒具有良好的分离稳定性，而结构稳定性较差。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
