胚层的

Metabolic activity quickly develops in the cells of the embryo and the aleurone layer .

胚细胞和糊粉层中的代谢活性立即活跃起来。

Results demonstrated that the level of ROS was greater in embryo than in aleurone layer, and only very little ROS could be detected in starch. Furthermore, the ROS produced in embryo were mainly localized inside cells but not on cell membrane.

结果表明，胚细胞产生的活性氧最多，糊粉层细胞次之，淀粉细胞几乎不产生活性氧；而且，胚细胞产生的活性氧主要定位在细胞内，细胞膜上不产生。

Aleurone layer The outermost proteinrich layer of the endosperm of grass fruits (e. g. cereal grains).

糊粉层：在谷类种子胚乳最外面的一层或几层细胞，含有大量的糊粉粒。

Histochemical staining of immature transgenic rice seeds showed UidA gene was specifically expressed in endosperm and the highest level GUS expression was observed in aleurone layer.

对转基因植株种子的GUS 染色表明，UidA基因仅在胚乳中表达，在糊粉层中GUS表达量最高。

Most angiosperm ovules possess two integuments, while gymnosperms usually have only one.

大多数被子植物的胚珠有两层珠被，而裸子植物通常只有一层。

Germ potential is established after conception in a totipotent zygote and retained subsequently during development in blastomers of morula , cells form the inner cell mass of blastocyst , epiblast and population of primordial germ cells .

种子潜能的确定是全能的受精卵形成之后，并且随后在桑葚胚，胚泡内层细胞，外胚层和原生殖细胞的发育过程中保留。

The ovule of development is the one nucellus that make a group at first organization, because basilar segmentation is rapidder and form or two bags by the layer, bead by , other nucellus the organization laps inside and next alveolus stays in one aspect of the matter, bead aperture .

发育的胚珠最初是一整团珠心组织，由于基部的细胞分裂较快而形成一层或两层包被层—珠被，将其他珠心组织包裹在内并在一端留下一个小孔—珠孔。

Results The expression of endogenous LN was found in the basement membrane of epithelium, glands and blood vessels in uterine endometrium of both estrus and early pregnancy. And its was faint that LN present in basement membrane as the implantation occurs, but the LN immunostaining in the epithelial cells of endometrium was stronger. The exogenous LN has no obvious influence on blastocyst attachment and implantation. LN-antibody intra-uterine injection showed significant repressing effect on mouse blastocyst implantation.

结果 动情期及妊娠早期小鼠子宫内膜内源性LN在上皮和腺基膜及血管内皮基膜均有表达，并随着植入的发生基膜的LN表达减弱，而内膜上皮中LN免疫染色逐渐增强；外源性LN对小鼠胚泡粘附与植入子宫内膜不产生明显影响，层粘连蛋白抗体明显抑制小鼠胚泡着床。

The scientist has made a pointed comparison between suspensors of plant embryos and mammalian trophoblasts.

这位科学家把植物胚的胚柄与哺乳动物的滋养层做了直接的比较。

In this study, in utero transfection plasmid DNA method was set up to embryonic mouse. The GFP expression vector pCAGGS-IRES-EGFP was microinjected into the lateral cerebral ventricle of E 14.5d mouse embryos through the uterine wall. Then, the 30 V square-wave pulse was delivered across the head for 5 times and interval 50m sec by electrodes in parallel with the median raphes.

本研究旨在通过子宫内电穿孔法，建立鼠胚大脑皮层体内基因转移体系：将带有绿色荧光蛋白的表达载体pCAGGS-IRES-EGFP显微注入胚胎期14.5 d的鼠胚侧脑室中，电极沿与脑中缝平行的方向夹持鼠脑，在电压30 V，脉冲时间50 ms，脉冲数5的条件下方波电击，将外源基因转移到室管膜层细胞。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
