减数

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。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。

The quantity from which another quantity, the subtrahend, is to be subtracted.

被减数一个要被另一个数，即减数，减除的数。

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。

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

Disruption of Sun1 in mice prevents telomere attachment to the nuclear envelope, efficient homologue pairing and synapsis formation in meiosis.

小鼠中Sun1基因的剔除破坏了减数分裂时期端粒的核膜附着，阻碍了同源染色体配对和联会的形成。

Synapsis The association of homologous chromosomes during the prophase stage of meiosis that leads to the production of a haploid number of bivalents.

联会：能产生单倍二价体的减数分裂前期，同源染色体的联合现象。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
