叶绿体

To elucidate the biological structure basis of transgenic rice plants expressing maize PEPC gene with high photosynthesis efficiency, PEPC transgenic rice and its wild type with at 3 leaves seedling stage were treated under 1000 μmol/(m^2s) light intensity for 100 min, respectively, and those under 200 μmol/(m^2s) light as the control. The structure of mesophyll cells, bundle sheath and thylakoids of the second blade were observed with a transmission electron microscope.

为了阐明转玉米PEPC基因水稻高光效的结构基础，以转玉米PEPC基因水稻和未转基因原种为试验材料，在水稻的三叶期，施以100min，1000μmol/的高光强处理，以200μmol下的水稻为对照，运用透射电镜观察叶肉细胞、维管束鞘以及叶绿体内类囊体片层结构。

Compared to wild-type plants, the onset of flowering was advanced. The results of this study may be useful in the mulberry gene engineering and the results may be helpful to study the regulation of SBPase.Rubisco activase is a soluble chloroplast protein, coded in nucleus, and has the activation of Rubisco in photosynthetic autotrophs.

本研究为桑树基因工程提供了有效的候选基因，为深入研究SBPase的分子调控机制奠定了基础。1，5-二磷酸核酮糖羧化酶活化酶广泛存在于光合生物中，它是一种由核基因编码的叶绿体蛋白，具有调节Rubisco活性的功能。

It turns out that some cell organelles are of microbial origin: mitochondria and chloroplasts definitely, cilia, flagella and centrioles possibly, and perhaps the nuclear membrane and much of the chromosome structure as well.

结论是，一些细胞器是微生物来源的，线粒体和叶绿体肯定是，纤毛、鞭毛和中心体可能是，核膜和大部分的染色体结构也许是。

The smooth exine is considered to be an evolutionary character.

孢子的颜色在遗传上具有相对稳定性，可能与生活环境、孢壁厚度、孢子体积、叶绿体数量和贮存物质有关。

20 Mol/L putrescine,0.5-5 mo!/L spermine could also get a raising trend of fruit set rates , but the results showed that the difference between the treatments and CK was not significant.

在果实转色期，果实中的叶绿素的含量逐渐减少，胡萝卜素含量增加，柿果成熟色泽显现出来，柿皮叶绿素和胡萝卜素的含量高于柿肉的叶绿体色素和胡萝卜色素的含量。

It might be concluded that the character of green-yellow bands induced by cold shock was consequent upon a reverse process of degeneration and regeneration.

由此可以推断，水稻1103s叶片间断失绿性状表达过程，实质上是一个由温度调控的叶绿体结构退化与修复的可逆过程。

The typical higher-plant chlooplast is lens-shaped and about 5 um in length.

在典型的高等植物中叶绿体一般为椭圆形或卵圆形，平均直径为5μ m 。

Blue light can improve the development of chloroplast,complex lig...

蓝光有利于叶绿体的发育，红、蓝、绿复合光有利于叶面积的扩展，而红光更有利于光合产物的积累；不同光质对不同植物、不同组织器官叶绿素积累的影响不同。

Tobacco plant infected with CMV containing satellite RNA 881 or satelliteRNA R1 show mild mosaic symptom,and a small amount of CP was detected in the chloroplast.

Two chloroplast, and one nuclear (18S) genes from 86 families, 126 genera, and 151 species of angiosperms (including 58 families, 86 genera, and 101 species of monocots), representing all major lineages of monocots and the basal angiosperms, were analyzed using parsimony methods.

基于两个叶绿体基因和一个核糖体基因(18S rDNA)的序列分析，对代表了基部被子植物和单子叶植物主要谱系分支的86科126属151种被子植物（单子叶植物58科86属101种）进行了系统演化关系分析。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
