叶绿体基粒

Using transmission electron microscope, I had found that there were obvious differences in the content of chloroplast and amyloplast and in the structure of grana lamella between transformed and wild tobaccos.

以转基因植株为材料，对植株叶片进行亚显微结构的透射电镜观察，发现野生型烟草与转基因烟草中的叶绿体、淀粉粒含量以及叶绿体中的基粒片层结构明显不同。

Results indicated that the variation was significant from treatment to treatment. S-deficiency caused bulging chloroplasts, loosening and dishevelled grana lamella, reducing organelle, and damaged chondriosome in mesophyll cells of the leaves, and empty cells of the roots, while S-excess, however, led to densification, condensation and randomization of grana lamella of the chloroplasts of the leaves, and separation of cytoplasms from walls of the cells of the roots.

结果表明，受S素营养胁迫的水稻，其根系及叶片的超微结构均发生了显著的变化：低S胁迫会造成水稻叶片叶肉细胞内的叶绿体结构肿胀，基粒片层松驰、散乱，细胞器减少，线粒体结构被破坏，根系细胞内几乎没有内含物；S浓度高则会使叶片叶绿体基粒片层致密、浓缩，无规则化，根系细胞发生质壁分离。

E., the number of stocs in granum abnormally decreased, thylakoid systemwas disintegrated and replaced by few single thylakoid, and then the whole structure of some chloroplast became vesicle-like structure with high electronic density.

电镜观察发现，性状表达时叶片间断失绿区叶绿体内部结构发生退化，呈现基粒垛叠片层数的异常减少，或基粒消失仅剩基粒残迹，有的甚至整个叶绿体为高电子密度的囊泡状结构。

Under normal temperature.the Ca2+-ATPase activity was found on the innerside of the PM.on the vacuole envelope and the chloroplast envelope,and theenzyme activity declined upon heat stress.The Ca2+-ATPase activity on the vacuoleenvelope,PM.and the chloroplast envelope in both Ca2+-and oxalate-treated peppermesophyll cells was higher than that in the control under the same condition.TheCa2+-ATPase was also found at the granum lamella,and it was activatedsignificantly by exogenous Ca2+ and oxalate treatments.Under heat stress.the Ca2+-ATPase activity declined slowly in both Ca2+- and oxalate-treated mesophyll cells.But La3+ treatment inhibited the enzyme activity under both normal condition andheat stress.

常温下生长的叶肉细胞，在质膜、液泡膜、叶绿体被膜等处有Ca2+-ATPase活性，热胁迫后酶活性下降；外源Ca2+和草酸预处理对辣椒叶肉细胞各种膜上Ca2+-ATPase活性具有促进作用，特别是定位于液泡膜、质膜和叶绿体被膜上的酶活性明显比对照提高；在叶绿体基粒和基质片层上也有酶活性，并且Ca2+和草酸预处理对该部位上的酶活性激活作用更明显；La3+处理的作用与Ca2+和草酸处理的效果相反。

The chloroplast ultrastructure of the sepal in the fresh-cut broccoli florets was investigated with a transmission electron microscope.

对鲜切西兰花叶绿体超微结构的研究表明，乙醇对叶绿体外膜及内部基粒片层结构均起到保护作用，减小了贮藏期间叶绿体的破坏程度，显著延缓了叶绿体结构的解体。

The CO2 saturation point and light saturation point of B ascended and CO2 assimilatory ability, efficienecy of light energy utilization and temperature effect increased.

低钾处理初期，B叶绿体基粒数多于A，并且片层密度加厚；低钾处理后期，B与A叶绿体结构与形态趋向一致。B的CO2饱和点上升、光饱和点上升，CO2同化能力增加及光能利用率、温度效应增加。

With electron microscope techniques, the cytopathological changes of the tobacco leaves infected by TMV-W and TMV-O 17 were observed.

受TMV-017侵染的烟草细胞中，叶绿体数量较少，叶绿体具双层膜结构，基粒片层排列整齐，有的叶绿体膨大，内含少量小的淀粉粒。

Compared with that of normal cucumber, the structure of photosynthetic apparatus in glabrous cucumber was simple with less numbers of chloroplast and grana as well as the grana lamellae.

与有毛黄瓜相比，无毛黄瓜光合机构的结构较简单，叶肉细胞内叶绿体数量少，叶绿体内基粒数和基粒片层数少。

The colorless ground matter between the grana lamellae in a CHLOROPLAST.

基质：是叶绿体内的叶绿体基粒片层结构之间的无色透明物质。

On the contrary, CC with small vacuolar structures and few mitochondrias, endoplasmic reticulums were shown in weak light.

在弱光条件下也观察到叶绿体基粒片层边缘紊乱，筛孔处于阻塞状态。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
