胚层

At germination, the embryo produces gibberellin, which stimulates the aleurone layer to synthesize enzymes, especially amylase.

在种子萌发过程中，胚产生赤霉素，赤霉素可以刺激糊粉层合成一些酶特别是淀粉酶。

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。

Phytates,the salt form of PA chelating with cations such as K~+, Ca~(2+),Mg~(2+),Zn~(2+) and so on,are mostly accumulated in the aleurone and embryo part of cereal seeds.

植酸是作物种子中含磷最丰富的化合物，占种子干重的1%以上，种子全磷含量的65%-85%和酸溶性肌醇磷酸盐的90%以上，易与K~+、Ca~(2+)、Mg~(2+)和Zn~(2+)等金属离子螯合形成植酸盐，主要沉积在作物的糊粉层和胚中。

With the assistance of molecular probes for reactive oxygen species, the production and localization of ROS derived from embryo, starch and aleurone layer of maize seeds with different ages were investigated under a laser scanning confocal microscope and a luminescence spectrometer.

借助活性氧发光分子探针，利用荧光光谱和激光共聚焦扫描显微技术，在不同年份的玉米种子吸胀早期，对其胚、淀粉和糊粉层细胞活性氧生成进行了定量和亚细胞定位分析。

" Rough rice" means that the rice still retains some of the outer organization,such as cortex, aleurone layer and germ of rice. They have a very high nutritional value, however, because their skin contains a lot of rough fiber and pectin substances, close texture, taste coarse and not easily digested by the human body,and cooking them is also quite time-consuming.

糙米是指脱壳后仍保留着一些外层组织，如皮层、糊粉层和胚芽的米，营养价值相当高，但由于其种皮含有大量的粗纤维和果胶物质等，质地紧密，口感较粗，不易被人体消化，蒸煮也比较费时。

Histo chemical staining of immature transgenic rice seeds showed UidA gene was spe cifically expressed in endosperm and the highest level GUS expression was observ ed 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。

After 16 weeks growth, continuous and intact ameloblast, enamel, dentin, odontoblast was found.

生长16周的人牙胚，已经形成连续完整的成釉质细胞，牙釉质、牙本质和成牙本质细胞层。

Results It was demonstrated that β-TrCP expressed in oral epithelium, tooth bud, mesenchymal cell cytoplasm of ameloblast and edontoblast of different stage of tooth development.

结果β-TrCP在胚胎10.5、13.5、14.5、16.5、18.5d的小鼠牙胚上皮层与间充质层，以及出生后0、3、6d的小鼠成釉细胞与成牙本质细胞胞浆呈特征性表达。

In the later period of ripeness, the protein bodies were extruded and filled with amyloplast.

成熟后期，蛋白质体因胚乳细胞中大小淀粉体的充实被挤成片层结构而填充在淀粉体缝隙中。

Shortly after implantation the blastocyst wall, the trophoblast, consists of two layers of cells.

植入之后不久，胚囊的壁，即滋养细胞含有两层细胞。

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。
