叶绿体

The research of cytology shows that there are dramatically morphological and structure changes in the leaf: the cells of mesophyll array loosely and parenchyma cells reduced, cambium becomes thinner and degree of xylem becomes more serious, the content of chlorophyll dropped; the changes of conducting tissue and stoma structure affect transport and allocation of water and nutrient, hinder leaf growth and disturb regular metabolism of leaf, at last lead to wilt, rot and become crisp papyraceous.

细胞学研究表明，病叶组织的叶肉细胞排列疏松，薄壁细胞层次减少，形成层变薄，木质化程度加深，叶绿体减少；在病叶中由于疏导组织和气孔的结构发生变化，影响养分和水分在植株体内的运输和分配，干扰叶片的正常代谢，抑制叶片的生长发育，最终导致叶片失水萎缩、干枯，变为焦脆的干纸状。

P. denasta harbored the three chlorotypes, two of which were characteristic of its two parental species respectively. The third chlorotype was extensively distributed in seven of the ten P. densata populations analyzed, and might represent a mutation type or have been derived from an extinct parent. Population differentiation of P.

TT和GC分别是油松和云南松种特异性叶绿体单倍型，而在高山松群体里则三种单倍型均有分布，而且TC单倍型广泛地分布在7个杂种群体中，该单倍型很可能来源于点突变或第三个已灭绝的亲本。rbcL基因检测到的高山松群体分化系数很高（G〓=0.533）。

The number of chloroplast and basal granule s and basal granule layers of leaf of grape in greenhouse were higher in pergola and onto layer in vertical trellis system than under layer in vertical trellis system.

葡萄棚架叶片和篱架上部叶片的叶绿体数、基粒数、基粒片层数明显高于篱架下部的叶片。

From a broader point of view, photosynthesis is but one of the interesting biological facet s of chloroplasts

从一个较广泛的观点看，光合作用只是叶绿体有意义的生物学特征中的一个。

Chloroplasts also show phototaxis,and take up specific orientations in relation to the direction of the incident light.

叶绿体也显示出趋光性，依据入射光的方向来调节其特殊方位。

In this study, we present the patterns of genetic differentiation of pitcher plant populations based on chloroplast DNA haplotype analysis using the sequences of five spacers.

在本文研究中，基于利用五个间隔序列的叶绿体DNA单倍型分析，我们提出了猪笼草种群的遗传变异模式。

Plasmagene A gene contained in a structure outside the nucleus , e.g. the genes in mitochondria and chloroplasts.

细胞质基因：位于细胞核外的一定结构中的基因，如线粒体和叶绿体中的基因。

The evident damage of chloroplast ultrastructure in S.polyrrihiza appeared at pH 2.5, but no severe plasmolysis and chloroplast swelling were seen.

紫萍在pH 3.5时膜系统的外渗率仍较低，基粒和基质类囊体结构无明显改变：pH 2.5时叶绿体结构才出现严重伤害，但未见明显的肿胀与质壁分离现象。

Recent studies have revealed that the FtsZ protein, known as a key com- ponent in prokaryotic cell division, is involved in chlo- roplast division process.

已经证明FtsZ 蛋白作为真核细胞分裂装置的一个关键成分，参与叶绿体的分裂过程。

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.
