叶绿体

After Cunninghamia lanceolata cones were infected by Pestalotiopsis apiculatus ,the ultrastructure of diseased cone scale cells showed a series of pathological changes according to the different infected degrees and it mainly showed that the granum lamella structure and membrane structure of the chloroplast were destroyed

侵染后，罹病果鳞细胞的超显微结构依侵染程度不同表现一系列病理变化，主要表现在：叶绿体的基粒片层和膜结构遭到破坏

The number of chloroplast in stomata guard cell, density, length and width of stomata were observed.

以苹果和梨的二倍体和多倍体为试材，比较了气孔保卫细胞叶绿体数目、气孔密度、气孔长和气孔宽四个性状与倍性的关系，分析各个性状用于倍性鉴定的可靠性，并采用两类性状同时进行判别分析，建立判别分析方程。

There is now strong evidence that chloroplasts and other cell organelles, such as mitochondria, represent prokaryotic organisms that invaded heterotroph ic eukaryotic cells early in evolution and are now part of an indispensable symbiotic union see endosy

这恰恰是现在有关叶绿体及一些其他的细胞器如线粒体是被原始的真核细胞吞噬进细胞内，与宿主长期共生而逐渐演化出独立单元的内共生起源学说的重要证据。

But the total chloroplast plan area per mesophyll cell was conserved in sense, antisense and wild type tobaccos.

同时还证明NtFtsZ2-1基因表达的变化对叶绿素含量和叶绿体的光合作用能力没有直接的影响。

There are three types of chloroplast-containing cells: palisade mesophyll cells, spongy mesophyll cells, guard cells.

在叶片中，有叶绿体的细胞包括三种：栅状叶肉细胞、海绵叶肉细胞、保卫细胞。

The present article aims to determining the activity of Hill reaction and the Myrica nana s chloroplast.

对贵州矮杨梅叶片叶绿体希尔反应活力和叶绿素含量的测定，并对其光合作用特征进行了初步的探讨。

The investigation of the function of FtsZ protein in Nicotiana tabacum will found a good foundation for us to know the molecular mechanism of chloroplasts division and the origin and evolution of eukaryotic cells.

将会为进一步认识叶绿体分裂的分子机制以及真核细胞的起源和进化等问题打下坚实的基础。

The significant changes were obseved in the morphology,size,number and the degree of development of nuclei,nucleole,mitochondrial and chloroplast of apicalmeristem cell.

在这期间茎端细胞内核仁、线粒体、叶绿体等的形态、大小、数量、发育程度等发生明显变化。

With increasing of salinity, there were no obvious difference in quantity and shape of chloroplast under SEM, but their location in palisade cells occurred change. All these changes made seedlings photosynthesis inhibited and growth stunted.

因此，盐胁迫下叶片栅栏组织厚度的下降、海绵组织中胞间隙的减少以及叶肉细胞中叶绿体的分布变化可能是导致植物光合效率下降和幼苗生长受阻的重要原因。

Phylogenetic relationships among the 18 original genera of the palm family were investigated using two DNA sequence data sets derived from matK, the maturase - coding gene located in an intron of the plastid gene trnK, and the internal transcribed spacer region of 18S-26S nuclear ribosomal DNA to examine relationships in 18 generas of chinese palm family.

通过叶绿体trnK基因的内含子matK序列及核糖体转录间隔区序列研究初步分析了中国原生棕榈科18属间的系统发生。

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。
