叶绿体

By assuming a common mutation rate of the cpDNA-IGS regions, our inferred timings of these events (0.82-4.39 Mya) broadly agrees with both previous geological and molecular estimated time of drainage rearrangements in this region.

基于叶绿体核苷酸平均替代速率，我们推测出了不同分支间的隔离时间大约在0.82-4.39Mya之间，结果与已有的鱼类分子系统的研究结果基本一致，也与现有的地质学文献关于红河改道的时间一致。

H higher than those for shanyou 63 respectively, the calcium contents in extracts, the Mg(superscript 2+)-ATPase activities on the chloroplast membranes, the cyclic photophosphorylation activities of the flag leaf sheathes and blades for Liangyoupeijiu were also higher than those for Shanyou 63; the means of noncyclic photophosphorylation activities of the flag leaf sheathes and blades for Liangyoupeijiu were 0.25 and 0.31 μmol/ higher than those for Shanyou 63, respectively; the photochemical avtivities of the flag leaf sheathes and blades for Liangyoupeijiu were significantly higher than those of its parents at most stages, showing heterosis over mid-parent or heterobeltiosis.

h，且大多数时期达显著或极显著水平；两优培九剑叶叶鞘及其叶片浸出液钙含量均显著或极显著高于汕优63；两优培九剑叶叶鞘及其叶片叶绿体膜上Mg(上标 2+)-ATPase活性的均值均高于汕优63，大多数时期达显著或极显著水平；两优培九剑叶叶鞘及其叶片循环光合磷酸化活性的均值也均高于汕优63，近一半时期达显著或极显著水平；非循环光合磷酸化活性的均值分别比汕优63高0.25和0.31μmol/mg？

Hill reaction The reaction, first demonstrated by Robert Hill in 1937, by which isolated illuminated chloroplasts bring about the reduction of certain nonphysiological electron acceptor with accompanying evolution of oxygen.

希尔反应：是1937年由罗伯特希尔首先证明的一种反应。离体叶绿体在光下可使某些非生理性的电子受体还原，并伴随着氧气的释放。

We found a clear trnK5'-matK-trnK3' structure in Ophioglossum petiolatum, Lycopodiella cernua and Selaginella doederleinii. PCR with degenerate primers failed to amplify any trnK or matK fragments from other ferns or allies. However, dot blot hybridization showed distinct signals in these plant failed to amplify matK fragments.

本论文鉴定原始陆生植物其他未被检视的重要类群中叶绿体matK基因的存在，结果发现瓶尔小草、过山龙、生根卷柏都有trnK5'-matK-trnK3'的结构，以RT-PCR侦测matK表现时，瓶尔小草和过山龙都有侦测到讯号，但生根卷柏却没有，显示matK的表现在原始陆生植物似乎不是那麼一致。

At the same time, the relationship between genera Machilus and Persea was also discussed. The result of chloroplast DNA analysis indicated that C. philippinense was closer to Machilus than to Cinnamomum. There was no difference between C. philippinense, Machilus thunbergii, M.

上述3个叶绿体DNA片段的定序结果显示菲律宾樟较靠近桢楠属，在3个片段多达31处变异处可供辨识的位置上菲律宾樟与桢楠属植物序列之间没有任何变异，而两者与樟树有15处发生序列变异或插入缺失，与酪梨亦有14处发生变异或缺失。

Carbon dioxide is 'fixed' by combination with the 5-carbon sugar ribulose bisphosphate,forming two molecu- les of phosphoglyceric acid.

光合作用的暗反应发生在叶绿体基质中，来自于光反应的 ATP和 NADPH被用来将CO2还原成糖类。

This project studied the mechanism of a newfound phytotoxin from Alternaria alternata Keissler that infects Crofton weed. According with the result from experiment, the project group drew a conclusion that the toxin did not inhibit respiration in mitochondrion, so the key problem was whether the toxin inhibited photosynthesis in chloroplast.

本项目重点研究新近分离纯化的紫茎泽兰致病型链格孢菌毒素的致病机理，项目组依据实验结果排除了毒素抑制线粒体呼吸作用的可能性，把重点放在毒素对叶绿体光合作用的影响上。

It is found that the age of the old Pinus bungeana have no significent effect on the structure of the chloroplasts and the content of chlorophyll.

本文主要研究古白皮松的衰老衰弱与叶绿体的超微结构及叶绿素含量的关系。

Besides chromosome DNA, has extremely few structure different DNA to exist in eukaryotic cell's line plastochondria and the chloroplast.

除染色体DNA外，有极少量结构不同的DNA存在于真核细胞的线粒体和叶绿体中。

In plant, moist mildew element through in competition cell chloroplast and line plastochondria ribosome and elongation factor EF-2 union position spot, thus suppresses the peptide chain the extension, the destruction cell's translation function, causes to organize the brown death sensitively.

在植物中，潮霉素通过竞争细胞叶绿体和线粒体中的核糖体与延长因子 EF-2 的结合位点，从而抑制肽链的延长，破坏细胞的翻译功能，使敏感组织褐化死亡。

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".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
