A micronuclear version of the GARP gene was amplified by polymerase chain reaction. The macronuclear DNA molecule carrying the GARP gene is 460 bp long and shows the characteristics of macronuclear chromosomes of hypotrichous ciliates.

大核中该基因的染色体全长460 bp,基因两端具有下毛类纤毛虫大核特有的端粒序列(C4A4C4A4C4A4C4),开放读框内含有一个TGA(88-99)密码子,在游仆虫中编码为半胱氨酸。

The first were by de Saussure, in 1679. Having put an infusorium in a drop of water, he saw it divide under his eye.

第一个涉足这方面试验的人是 Saussure ,他在1679年时做过一个试验,将纤毛虫放入一滴水中,用肉眼就能观察到它的分裂过程。

The infusorium is subject only to accidental death, such as we can cause by the addition of some poisonous element to the water in which it lives, or by heat.

纤毛虫只会意外死亡,比如我们往它们生活的水域投毒或者加热这片水域等等。

The macronuclear and mitochondria DNA between the resting and the vegetative cell of Euplotes encysticus were comparatively analyzed by using RAPD technique in order to explore the acting feature of two genetic systems in the resting cell of ciliates.

为了探索纤毛虫休眠细胞中两套遗传系统的作用特征,对包囊游仆虫休眠细胞与营养细胞大核DNA和线粒体DNA进行了RAPD比较。

Male flower: disc dentate-lobed. Fruiting catkin 12-20(-30) cm; rachis pilose; bracts palmatiparted, brown, obovate-elliptic, ca.

In the early 1980s, many researchers revealed the structure of cytoskeleton mainly on kinetosome in the cortex by the employment of protargol staining and ultrastructure method, and thus the configuration, development and mechanism of cortical ciliatures were discussed, which was the major tide in the studies of cell biology of protozoa.

但是,目前仅对草履虫、四膜虫中分散排布的体纤毛基体的装配有较深入的了解,而对不同种纤毛虫的毛基体特别是紧密聚集排列的纤毛器基体微管的装配和基体微管装配在细胞内的启动和发生过程尚未进行深入的研究。

Three species: Ancistrocoma primigenius,Ancistrocoma pelseneeri and Hypocomides weihaiensis were morphologically investigated based on living observations,protargol impregnation and wet silver impregnation techniques,of which Ancistrocoma primigenius and A.

摘 要 报道采自山东沿海贝类鳃表及外套腔中寄生/共栖的3种吻毛类纤毛虫:原生钩毛虫、派氏钩毛虫及威海下毛虫。

Three species: Ancistrum crassum, Ancistrum japonicum and Boveria subcylindrica were morphologically investigated based on living observations, protargol impregnation and wet silver impregnation techniques.

摘 要 报道山东沿海贝类鳃表及外套腔中共栖的3种触毛亚目盾纤类纤毛虫:厚鱼钩虫、日本鱼钩虫及亚桶形后口虫。

The protozoa distribution varies with the CWD ages. Its number and the numbers of three main faunas increase with the going up of CWD ages. The percentages of Flagellate fauna, Sarcodina fauna and the Infusorians fauna percentage are respectively 26%-27%, 73% and 0.06%-0.07%.

原生动物的分布随着倒木年龄的增长,其数量以及原生动物的三大类群的数量均有所增加,鞭毛虫类群基本占26%~27%之间,肉足虫类群基本占73%左右,纤毛虫类群基本占0.06%~0.07%之间。

It is suggested that the algae symbiot can affect host organellar function,quantity and location, stimulate the food uptake and digestive activity, restrain the functional activity of the organelle, change the gene expression and cause the change of genome structiure in the P. bursaria-chlorellae system.

据结果推测,纤毛虫中的藻类共生体可影响宿主细胞中胞器的功能、数量和分布,可影响细胞核核仁的数量和分布;可影响宿主细胞的形态、生长、抗氧化能力及胞质糖含量;可影响宿主细胞的食物摄取及相关胞器的消化活性,抑制宿主胞器的功能活动;并可改变宿主细胞基因的表达,导致细胞基因组结构的变化。
