查询词典 embryo

Zygotic embryo is better than vegetative materials when used for explants.

合子胚作为外植体明显好于营养器官作为外植体。

Keywords: Two-cell block; zygotic gene activation; mouse embryo

中文关键词：细胞阻滞；合子型基因激活；小鼠胚胎

Mouse zygotic genome is activated at the two-cell stage which implies that embryonic development is transferred from the oocyte itself to the embryo.

在小鼠胚胎发育研究中发现，小鼠的基因组激活发生在2细胞期，这一时期标志着合子的发育由卵母细胞控制向胚胎控制的过渡，期间发生一系列复杂的生化过程。

Embryoids occurred in all stages as zygotic embryo and were asynchronous. embryoids were white and opague.

体胚分化经历与合子胚相似的发育过程，有球形期、心形期、鱼雷期和子叶期，体胚发生是不同步的，在同一块愈伤组织上有处于不同发育阶段的体胚。

Although Pygo expressed ubiquitously in the embryo, it expressed at relatively high level in pre-blastoderm embryos which indicated a high degree of maternally provided message, followed by a low level of ubiquitous zygotic expression.

结果表明，虽然pygo普遍表达于整个胚胎中，并且在果蝇胚胎发生全过程都有，但Pygo在前囊胚层(pre-blastoderm)中的表达水平相对较高，这说明胚胎发生过程中来自母方的贡献较高。

Embryo cells display a synchron cleavage rhythm during the cleavage stage, there is almost no gene transactivation, which is regulate and operated by the mRNAs and protein of oocyte.

卵裂阶段的胚胎细胞呈现同步化的分裂节律，鲜有基因转录活动，其发育由源自卵母细胞发生期间合成的蛋白质和mRNAs调控。

Ningxia Syngen Bioengineering Center (Ningxia Domestic Animal Breeding Center) established in June 23 of 2000, based on reform of Ningxia Cow Embryo Bioengineering Center.

宁夏四正生物技术工程研究中心是宁夏牛胚胎生物工程中心进行整体改制的基础上，于2000年6月23日组建而成。

In this study,Using extracted total DNA from duck plague virus vaccine strain infected Chicken embryo fibroblasts cells as template, the 1.0 kb TK gene nonessential for viral replication was amplified by polymerise chain reaction and cloned into T-easy vector to obtain pGTK.

本研究从感染鸡胚成纤维细胞的鸭瘟病毒疫苗毒株中提取了总DNA，并以此为模板，利用PCR技术扩增出病毒生长非必需的TK基因(约1.1kb)，将其克隆入pGEM-T easy载体获得载体pGTK。

These mtDNA copies are apportioned,without mtDNA replication, to cells of the early embryo.

在mtDNA不复制的情况下，它们被分配到早期的胚胎细胞中。

Then by the tracking investigation of the herbicide resistance of generations crossed or backcrossed with Bar gene transgenic wheat and the wheat hybrid descents heredity performance were studied. The result indicated that: 1 Development of regeneration systemsWheat genotypes and medium are the key factores influencing the development of regeneration systems for immature embryo cultivation.

此外通过回交将抗Basta除草剂的Bar基因转育到这些小麦品种，通过对转Bar基因小麦人工杂交与回交后代除草剂抗性的连续跟踪鉴定，研究了Bar基因在小麦杂种后代的遗传表现。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
