液泡

A development-course observation of the morphological changes in the nucellar cells undergoing PCD to form pollen chamber was performed.

在珠心细胞发生PCD的过程中，其形态变化显著，有序地降解细胞组分，其间液泡起着关键作用。

In addition, lipid droplets and starch granules had the same cycles as proteinaceous material.

油滴和淀粉颗粒的年变化情况同液泡中的蛋白类物质基本相似。

The suitable concentration of free Ca〓 and the suitable pH for the activity of the tonoplast-bound CDPK was 10μmol/L and 6. 5, respectively. Its active site was provably oriented toward the cytoplasm.

用我们建立的非放射性同位素测定方法和免疫印迹鉴定了液泡膜上存在一种具有钙依赖蛋白激酶活性的膜固有蛋白。

The results showed that,in spiteof many ultrastructural changes of the fruit epidermis cells during the fruit development,itremained almost unchanged that the cytoplasm was filled with numerous endoplasmic reticulathroughout the whole developmental process.Most of these endoplasmic reticula were tube-likeand rough-ER with enlarged cisterna from which were produced many vesicles. Some of thevesicles were shown to merge into vacuole and to traverse through plasmadesmata.

结果表明，虽然不同发育期果皮细胞的超微结构发生了变化，然而最引人注目的是，内质网自始至终密布于整个细胞质中，而且大多为槽库膨大的、合成功能旺盛的管状粗面内质网，并分泌出大量的具运输功能的小泡：观察到这些小泡与液泡融合和穿越胞间连丝的景象。

The following results have been obtained: 1 Expression of SbNHX1 in E. coli enhanced Na+ and K+ tolerances, but not to others; 2 The sequence from 1353-1514bp in SbNHX1 gene played a role for SbNHX1 to Na+ and K+ tolerances; 3 The Na+/H+ antiporter of Salicornia Bigelovii Torr. catalysed Na+/H+ or K+/H+ exchange with equal affinity, which indicates that the SbNHX1 is more likely to locate on member of vacuolar, and responds to transport Na+ into the vacuole from cytoplasm.

证明了SbNHX1能抵抗Na+和K+的胁迫，但对其它盐离子没有抗性；2）证明了北美海蓬子Na+/H+逆向转运蛋白基因（SbNHX1）C末端从基因的C末端1353bp至1514bp的序列在耐盐中起一定的作用；3）证明了北美海蓬子Na+/H+逆向转运蛋白（SbNHX1）对Na+和K+交换的等亲和性，对于这一点，说明北美海蓬子Na+/H+逆向转运蛋白与定位于液泡膜上的Na+/H+逆向转运蛋白的功能相似。

The abnormality appeared in sporogenic stage and later followed vacuoles and enlarged taptum.

在小孢子发育过程中，绒毡层细胞出现液泡化、肥大、增生等异常现象。

Considerable progress has recently been made in studies of the specialized structure and function of guard cells and the mechanisms of stomatal movement.

保卫细胞的特殊结构和气孔功能密切相关，对保卫细胞壁特性、质膜上的各种结合蛋白、质膜和液泡膜上的离子通道的研究，以及对细胞骨架和气孔运动的关系的探索为阐明气孔运动的机理提供了更多的依据。

The major changes include sparse and short and loose microvilli of endodermal epithelium cells, a reduction in apical microvesicles and subapical storage vacuoles, swilling of the mitochondria and a reduction or disappear in its cristea, a decrease in rough endoplasmic reticulum, abnormation in pattern and structure of nucleus, an increased vacuolation in cells, an extend in the interval of adjacent cells.

电镜观察发现，剂量在50g/mL以上时，YS上皮细胞微绒毛稀疏变短，胞质中贮液泡减少，线粒体、内质网等内膜系统发生多种细胞病理学改变，细胞间隙增宽，连接复合体破坏。

The abnormity of tapetal cells vas also an important reason for the degeneration.

另外，绒毡层细胞质的液泡化也是小孢子败育的一个重要原因。

Stacked rER cisternae dilated and rER blebs formed; tapetal cell nuclear envelopedistended and nuclear pores increased in number.

在自由小孢子期，绒毡层内质网发生叠堆，可能是对小孢子液泡化后产生的膨压和张力的一种适应。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
