减数分裂

A cell from which gametes develop by meiotic division, especially a spermatocyte or an oocyte.

Previous studies have demonstrated that primary spermatocyte can undergo meiotic divisions in MI oocytes and the resulting embryos can develop to term. However, the success rate is very poor.

已经证明初级精母细胞在显微融入MI卵母细胞后可以完成减数分裂并且产生的胚胎可以发育到期，只是发育率还非常低，作为一种形式的核移植，细胞周期的同步化处理对于胚胎的发育具有重要意义。

Cloning of spermatogenesis related genes and further functional study are very important to the elucidation of molecular mechanism involving in spermatogenesis and spermiogenesis process.

克隆睾丸精子发生相关基因并研究其功能，对于揭示精子发生过程中减数分裂和变态的分子机制，对于临床男性不育的诊断和治疗以及男性分子节育等均具有重要的意义。

2PKC inhibitor—staurosporine or sphingosine could also inhibitthe stimulatory effect of FSH(100IU/L);while PKC activator,phorbol myristate acetate,at the concentration of 10-8-10-5M had a dual effect on the meiotic resumption of pig CEO.

2PKC的抑制剂——Staurosporine(10-9-10-6M)或Sphingosine(10-8-10-5M)也能够显著抑制FSH(100IU/L)的刺激作用；然而PKC的激活剂——PMA(10-8-10-5M)对猪CEO减数分裂的恢复具有双相作用。

The development of a gametophyte directly from a sporophyte without the occurrence of meiosis or spore formation.

无孢子形成，无孢子生殖，无孢子状态没有经过减数分裂或孢子形成而直接由孢子体进行的配子体发育

Based on principle of pollen abortion, utilizing tapetum of anther cell, mitochondria of tapetum, callose well, process of cell meiosis during formation process of pollen, we adopt genetic transformation to create plant male sterility, such as, exogenous cytotoxin gene, chaperones, anti-sense RNA, degradation of callose ahead of time, disturbing information intercommunion between mitochondria and nucleolus and affected development of pollen sporule by bacteria.

根据花粉败育的原理，利用花药细胞绒毡层、绒毡层线粒体、胼胝质壁、细胞减数分裂过程等花粉形成过程中的不同环节，采取外源细胞毒素基因、分子伴侣、反义RNA技术、提早降解胼胝质、扰乱线粒体与细胞核之间的信息交流和细菌影响花粉小孢子发育等策略，使花粉不能正常形成，从而产生不育花粉，达到产生雄性不育的目的。

There are not differences in the meiosis of both A lines and B lines , and between CMS of hot and sweet pepper.

椒细胞质雄性不育系金A 和保持系金B 减数分裂和雄配子发生的整个过程。

The first stage of meiosis, constituted by a series of events that include DNA replication, the synapsis of homologous chromosomes, crossing over, the formation of chiasmata, and contraction of the chromosomes.

前期阶减数分裂的第一个阶段，由一系列的事件组成，包括脱氧核糖核酸的复制，同种染色体结合、交叉，染色体形成以及染色体的收缩一套，一系列

In synapsis Red1, Hop1 and Zip1 are the components of synaptonemal complex. Hop2 is required for synapsis.

Red1、Hop1和Zip1是联会复合体的组成成分，而联会也要求其他减数分裂的特异性基因如Hop2的参与。
