查询词典 guard cells

In the fin219-null mutant background, GUS staining can be detected in the hydathode of cotyledons, and the guard cells around hydathodes. GUS staining are also found in the base of trichomes, hypocotyls and roots. In contrast, in the phyA mutant background, GUS-FIN219 was not expressed in the hypocotyls.

结果发现转殖在fin219-null突变株背景下，FIN219会特别表现在植株叶缘出水孔与附近的保卫细胞及毛茸基部、初生叶、下胚轴、根部等处，然而在phyA缺失的时候植株幼苗的FIN219则不会在下胚轴表现。

Each stoma is surrounded by two crescent-shaped GUARD CELLS, attached to each other at their ends, which regulate the opening and closing of the pore by changes in their turgidity.

保卫细胞可以因为自身紧张度的改变而规律性的开闭。

In addition, like ascorbic acid, an important reducing substrate for H2O2 removal, but unlike diphenylene iodonium, an inhibitor of the H2O2-generating enzyme NADPH oxidase, PD98059 and TFP not only reduced exogenous H2O2 levels in guard cells in light, but also eliminated the H2O2 that had been generated during a dark period and promoted stomatal opening.

另外，和H2O2的产生有关的NADPH氧化酶的抑制剂二苯基碘的作用效果不同，而和H2O2的清除剂抗坏血酸的作用效果类似，PD98059和TFP不仅能够降低光下保卫细胞的外加的H2O2水准，而且还能清除由黑暗条件诱导的已经产生的H2O2，并能引起气孔开放。

Guard cells : control the size of stomatal opening.

保卫细胞：控制气孔张开的大小。

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 characters in Impatiens, such as shape and lenghth of stomata, T-thickening at the polar region of guard cells and ornamemtation of leaf epidermis are more important between species and can be used one of the taxonomically important characters of Impatiens.

叶表面纹饰，气孔的形状、大小及气孔保卫细胞两极&T&型加厚等特征在种间具有一定的差异，可作为该属植物分类的重要特征之一文中还探讨了叶表皮微形态学特征在凤仙花属分类中的意义及有关紫花黄金凤的分类学地位间题。

Three types of cuticular thickening at the polar region of the guard cells are observed: slight cuticular thickening; rod-shaped culicular thickening and rarely T-shaped thickening.With data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted byout-group comparison using, the related genus Kadsura. as result, a new system of the genusSchisamdra Michaux was reconstructed, and Schisandra Michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation.

整理有关五味子属植物研究的资料，补充搜集近期发表的资料和本人研究所得数据，以种为基本单元，选择近缘的南五味子属作为外类群，采用PAUP4.0b4a软件对本研究得出的性状数据作分支分析，重建五味子属的系统发育，修订和补充五味子属分类系统，在五味子属下设2亚属、3组、2系、10种。
