To enhance the aphid-resistant, gene GNA34 was directly mutagenized to revert 9 of XCGs and XTAs of the least favored codons to preferred codons in dicots without changing amino acid composition.

为了提高所克隆的GNA34基因在双子叶植物中的抗蚜活性，我们对GNA34基因进行了改造。

The main root axis from which smaller root branches arise; a root system with a main root axis and smaller branches, as in most dicots.

直根 Taproot 具有侧根的主根轴；由主根和侧根组成的根系，见于大多数双子叶植物。

In a word, we extracted first cotyledon of buckwheat total RNA, by method of RT-PCR and 3RACE, get the C terminal cDNA sequence of PI from Ukraine buckwheat, and do some bioinformatics analyse on this cDNA sequence of PI from buckwheat, such as gene characteristics, expression mode. All of this will be help for the forward research on functional protein and high performance of procaryon expression or eukaryon expression.

综上所述，我们利用RT-PCR和3′RACE技术首次从吉乌一号甜荞第一对子叶中克隆获得荞麦蛋白酶抑制剂基因并对其基因特性、表达模式进行生物信息学分析，同时构建了该基因序列羧基端原核表达载体，为今后进一步研究荞麦功能性蛋白的分子机制及高效原核、真核表达载体的构建奠定了基础。

Globe-shaped yellow is h-green calli were chosen from the first subculturing for suspension culture in liquid MS medium containing 0.05-0.1 mg.

选用新疆雪莲子叶为外植体，接种于MS+0.5 mg.L-1 2，4-D+0.05-1 mg.L-1 BA的固体培养基上，进行愈伤组织的诱导。

The callus induction of licorices was easy. And the MS+1.0 mg/L NAA+1.0 mg/L 2, 4-D +1.0 mg/L 6-BA was the best medium to cotyledons, hypocotyls and radicles. And all the induction rates were 100%. 4. In the study of callus regeneration, only obtain the regeneration plants of hypocotyls callus,and its frequency was 4.57%.

甘草离体再生中愈伤组织的诱导较为容易，三种外植体子叶、下胚轴和胚根均以MS+1.0 mg/L NAA+1.0 mg/L 2，4-D+1.0 mg/L 6-BA为愈伤组织诱导的最佳培养基，在此培养基上，3种外植体愈伤组织诱导率均达到100%。

In conservative families, there has been little or no change in the number of genes since the divergence between eudicots and monocots ~145 million years ago.

在保守的家族中，基因的数目在大约一亿四千五百万年前(~145MYA)真双子叶植物和单子叶植物发生分化之后都没有改变或者变化甚微。

Although the model doesn't suit to monocots, but it has helped to analyze new genes and gene functions in monocots. Although lilies are among the most important ornamental plants, relatively little research has been conducted on lily flower development.

虽然有证据表明依据拟南芥、金鱼草等双子叶植物提出的ABC模型，并不完全适用于单子叶植物，但是仍然给人们在单子叶植物花发育相关基因的克隆和功能研究中提供了参考和借鉴。

Under different culture conditions CAT activity in the cotyledons and radicles had a tread of decrease with prolongation of culture time, while POD activity had a tread of increase.

不同培养条件下，随着培养时间的延长，子叶和胚根中的过氧化氢酶活性呈下降趋势，而过氧化物酶活性呈上升趋势。

The factors of temperature, light and salinity concen, with 3 levels were set up to make the germination experiment of cowpea seed. The germination rate was calculated and the catalase and peroxidase activity in cotyledons and radicles were investigated.

方法］设置3个水平的温度、光照、盐浓度进行豇豆种子发芽试验，计算发芽率，测定胚根和子叶中的过氧化氢酶和过氧化物酶活性。

Any of a group of hybrid garden primroses having clusters of variously colored flowers.

樱草花属的双子叶植物科带有整齐的花；广泛分布在北半球。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
