基因多效性

Sinorhizobium meliloti can fix nitrogen at the symbiotic phase, as it differentiates into bacteroid in the

还与结瘤有关，即它的调节功能具有多效性。但S。 meli loti 中究竟有多少基因的表达与nifA 相关

At polymorphic gene locus, the variance components of quantitative trait was described as follows:VA=2βp and VG=p′Xp-G2 in which p=column vector of polymorphic allele frequencies,β=row vector of2,X=［a2ij］i×i matrix,aij=genotype value,and G=population mean.

数量性状相对多态座位的加性方差和遗传方差分别为VA=2βp和VG=p′Xp-G2，其中p′和p分别表示多态等位基因频率的行向量和列向量，X表示以基因型值平方为元素的矩阵，β表示以基因均效平方为元素的行向量，G为群体均数。

At the same time, it also help us understand the pleiotropic action of simvastatin.

这些结果对于从基因表达水平上阐明针刺降脂的机理，以及寻找辛伐他汀治疗作用的多效性机制有着积极意义。

In this paper, the characteristics and safety of bar gene, PAT proteins and glufosinate were expatiated. The bar gene and glufosinate play important roles in plant engineering, and bar sequences are considered to be as safe as any other DNA in food and have no pleiotropism.

本文对除草剂草丁膦及其抗性基因之一－bar基因及其产物PAT蛋白的一些特性和安全性作了阐述。bar基因及筛选剂草丁膦在植物基因工程中发挥着重要作用。bar基因无多效性，与食物中的DNA一样安全。

The QTLs controlling the three traits had the same direction on additive effects and dominant effects. And these traits showed bimodal or discontinuous distributions in respective NILs. These results imply that the same gene might control the three traits simultaneously (i.e.; the gene pleiotropism).

两个近等基因系的QTL分析结果表明，3个性状都是由一个QTL或紧密连锁的QTL控制，而且加性效应和显性效应的方向均相同；同时3个性状在各自的近等基因系中呈现典型的双峰分布或不连续分布，这些结果暗示3个性状可能是一因多效的结果。

Thus, further research was needed to discuss whicn kind of blood protein loci can be used as genetic marker of sheep prolificacy to discover the relationship between sheep prolific traits and major effect genes.

因此，关于有些血液蛋白位点可作为绵羊多胎性的遗传标记物，还需要深入研究，以更有效地揭示绵羊多胎性与有关主效基因的关系。

The analysis of Wr+Vr showed that the additive effect was major and the susceptibility was partially dominant.The inheritance of resistance in the highly resistant accessions(Calhoun Gray、Sugerlee) to race1 conform to a single dominant gene conditioned the resistance and there was significant correlation between the genes controlling the characters.

试验结果表明：西瓜对枯萎病抗性是由隐性多基因控制，其遗传符合加性-显性模型，加性效应比显性效应更为重要，且感病对抗病表现为部分显性，显性方向指向增效，隐性基因为减效，在所有亲本中所携带的隐性基因比显性基因多。

There were significant differences (P＜0.05) between cock's and hen's body length, chest bone length, thurl width, shank circumference in some Chinese indigenous chicken breeds. There were significant differences (P＜0.05) between cock's and hen's shank length among 12 Chinese indigenous chicken breeds. The differences showed that some genes controlled sex may be responsible for the differences of sexuality, on the other hand, they affected cock's and hen's body measurements and body weight, that is one gene has multiple effects.

大部分地方鸡品种12周龄公、母鸡在体斜长、龙骨长、骨盆宽、胫围和体重之间存在显著的差异（P＜0.05），12个地方鸡品种内12周龄公、母鸡胫长之间均存在显著差异（P＜0.05），这些结果说明了控制公、母鸡性征的一些基因，一方面使公、母鸡在性征的表现上存在差异，另一方面这些基因也对公、母鸡的体尺和体重等性状起着一定的作用，即表现为一因多效的作用。

Carotene and bixin inhibited the of MCF-7 human breast cancer cell significantly. The effects of carotenoids were pleiotropic.β-Carotene can activate PPARγ signal pathway and regulate expression of the downstream and relative genes, and impel cytochrome C liberation from mitochndria and increase the level of reactive oxygen species in cell.

胡萝卜素与胭脂树橙显著抑制乳腺癌MCF-7细胞的生长，β-胡萝卜素的抑制作用可能是多效性的，一是激活PPARγ信号系统，调节PPARγ下游基因及相关基因表达，另一个是促使线粒体中的细胞色素C释放，引起细胞内活性氧生成增加，导致细胞活力下降或坏死。

In this study we mapped a grain length controlling gene named Lk-4 with SSR and CAPs markers by screening 800 recessive plants in a BC2F2 population derived from a cross of Shuhui527×Xiaoli and backcrossed with Xiaoli as the donor parent.

对F2和BC2F2 群体籽粒大小形状和千粒重的遗传分析表明，回交能将大部分对目的基因效应具有干扰修饰作用的微效基因多态性除去，从而有利于对目的基因型的准确鉴定；在F2和BC2F2群体中只发现两类籽粒长短表现型，即短粒和长粒，并且二者分离比例符合3：1的典型一对等位基因分离比例。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
