偶线期

In Peiai 64S, the microtubules showed abnormal patterns of distribution from pre_meiotic interphase to metaphase Ⅰ. For example the broad band of perinuclear microtubules seen at diakinesis in IR36 was much disorganized and loosened in Peiai 64S.

(1)在偶线期具极性分布的微管分布不存在；(2 )在小孢子母细胞减数分裂期间的细胞内出现许多特别粗的微管束；(3)在终变期围绕核的微管宽带结构松散及内含微管密度低。

Modification of plasmodesmata occurred at leptotene stage, at which the cell wall was degraded by the release of the enzymes from the endoplasmic reticulum-derived vesicles after its fusing with the plasma membrane .

前者形成于细线期末，造成细胞壁降解的物质来自内质网分离到细胞质中的内质网小泡；后者形成于偶线期以后，造成细胞壁降解的物质来自于内质网与细胞质膜融合后内容物的释放。

The karyotype of Nelumbo nucifera during meiosis zygotene was established in this study,which would help the studies of meiosis and molecular cytogenetics in lotus.

本研究建立了中国莲偶线期染色体的核型，为研究莲的减数分裂过程及分子细胞遗传学研究提供基础。

Zygotene is characterized by the active and specific pairing of homologous chromosomes leading to the formation of a haploid number of bivalents.

偶线期时，以同源染色体活跃的、特定的配对为特征，形成了单倍数的二价染色体。

Zygotene nodules and development of the brown ratRattus norvegicus caracohave been studied, by surface spresding with SDS treatment, silver and phosphotungatic acid staining techniques.

采用表面铺展－SDS处理、硝酸银和磷钨酸(Phosphotungstic acid，PTA)染色电镜技术，研究了褐家鼠精母细胞中常染色体联会复合体（Synaptonemal complex， SC）的发育及偶线期节（Zygotene nodule， ZN）。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
