保卫细胞

In this article, we review the labeling methods and organization of actin filaments in guard cells, we also describe their role and the possible mechanism in signal transduction of guard cell.

本文综述了保卫细胞微丝骨架的标记方法、结构，以及其在气孔运动中的功能和作用机制的最新研究进展。

In closed stable stomatal guard cell, long filaments randomly distributed in cortex.

在关闭的气孔保卫细胞中，较长的微丝散乱分布在整个周质区域。

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。

The results showed that the cluster analysis indicated that ploidy was highly correlated to the number of chloroplast in guard cell and the length of stomata.

结果表明，叶绿体数目和气孔长鉴定倍性的可靠性较高，其中，苹果气孔长误判率最低，为6.67 ％；梨气孔保卫细胞叶绿体数目误判率最低，为12.5 ％。

This data not noly suggest that polymerization-depolymerization is important to stomatal movement and stability, but also interpret conflicting results whether actin polymerization or depolymerization in stmatal guard cell.

这不仅提出了肌动蛋白解聚—聚合在气孔开关运动和稳定性中的重要作用，而且可以解释保卫细胞中肌动蛋白是处于解聚状态还是聚合状态的不同报道。

When stomatal closure, K +,Cl - contents decreased obviously in vacuole and cytoplasm, but increased in cell wall of guard cells.

伴随着气孔关闭，保卫细胞液泡和细胞质中的K^ 、Cl^-含量都明显下降，而细胞壁中的K^ 、Cl^-含量增加。

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。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
