叶绿体

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3-phosphate, the first step in the Calvin cycle.

在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3－磷酸甘油酸，这是卡尔文的循环第一步。

Further study was carried on the cpDNA matK in Hamamelidaceae and its systematic significance (the sequences of matK of some species have been obtained, and the research have been funded by NSFC), and molecular and systematic study were also carried on Magnoliaceae, Rhizophoraceae, Labiatae.

在此基础上，开始了对金缕梅科叶绿体DNA mtK基因及其系统学意义的研究（已测定部分种类的matK基因序列，并获国家自然科学基金国际合作项目的连续资助），同时对木兰科，红树科，唇形科植物类群开展了分子系统发育研究。

Bioassays showed that the product of cry1Aa10 gene was high toxic to Heliothis armigera larvae, indicating that the constructed vector is useful for chloroplast transformation and it will lay a basis for obtaining strongly insect-resistant oilseed rape.

这些结果说明所构建的载体具有可使用性，它为进一步开展油菜的叶绿体遗传转化和获得高抗虫油菜奠定了基础。

PCR and Southern blotting analysis confirmed stable integration of phaC2 into the chloroplast genomes of T0 and T1 transgenic plants, and T1 transgenic plants exhibited homoplasmy.

对T0代和T1代转基因植株的PCR和Southern blot鉴定结果表明，外源基因确已整合进烟草叶绿体基因组中，T1代转基因植株已达同质化。

The psbL-psbJ region of chloroplast DNA of 8 and 2 Hordeum species or subspecies from China and other countries, respectively, were investigated by PCR amplification and direct sequencing.

对8份来源于中国和2份来自国外的不同大麦属物种或亚种叶绿体基因组psbL～psbJ区进行了序列测定。

Observation under optical and transmission electron microscopes showed that the Cu-contaminated leaves were thickened, with the expansion of leaf cell and the incrassation of palisade tissues. The yellow leaves might result from the damage to chloroplasts. Cortical cell death in root system might also have a negative effect on root water absorption and transportation, causing plant water content decreased.

通过光镜和投射电镜观察，发现紫云英污染叶变厚，其原因是叶片细胞膨大和栅栏组织增厚；叶片转黄与叶绿体遭破坏有关；根系部分皮层细胞死亡可能影响根系吸水和植株水分运输，导致植株含水率降低。

In this report, major features of the new device are outlined and examples of its performance are presented using suspensions of Phaeodactylum tricornutum and of freeze-dried thylakoids of Lactuca sativa.

本文介绍了该仪器的主要特性，并且以三角褐指藻培养液和冻干的莴苣叶绿体悬浮液为测试生物阐明了仪器的使用方法。

The influence of three kinds of heavy metal on the activities of peroxidase, superoxide dismutase,catalase and the contents of malondialdehyde, soluble protein and chlorophyll of Lemna minor was investigated.

对水体中主要的3种重金属对青萍抗氧化酶系统的几种酶，包括过氧化物酶、超氧化物歧化酶、过氧化氢酶的活性，丙二醛的含量，可溶性蛋白含量及叶绿体色素含量等指标的影响进行了研究。

Changes of carbohydrate contents, sucrose-metabolizing enzymes activities and chloroplast ultrastructure in tomato（ Lycopersicon esculentum Mill.）leaves that were treated by 30 ℃ and 35 ℃ were studied to investigate the effects of high temperature on carbohydrate metabolism of tomato. Plants were treated by 30 ℃ and 35 ℃ in daytime after the 1st inflorescence effloresced, and plants that under 25 ℃ were considered as control.

以'辽园多丽'番茄为试材，以昼温25℃为对照，对植株进行30℃和35℃高昼温处理，探讨在高昼温条件下，叶片碳水化合物含量、蔗糖代谢酶活性以及叶绿体超微结构的变化。

The 1 039 bp sequences of the chloroplast matK gene from nine species relating to Parakmeria and Kmeria of Magnoliaceae were determined.

测定了木兰科拟单性木兰属等10种(11个样)植物的叶绿体DNA matK基因部分序列(1 039碱基对)。

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.

这是凯特，那个是爱朗。
