查询词典 gynogenesis

However, whether these bands caused by recombination were hard to perorate owing to the analysis method restriction. 2. Isozyme mean proportion of polymorphic loci and the average heterozygosities of gynogenesis population in Paralichthys ohvaceu were 6.90% and 0.03 50 respectively.

牙鲆雌核发育群体同工酶的Ldh-C，Cat两个基因座位发生了重组，基因座位与着丝点之间的重组率分别为52.6％和29.8％；雌核发育群体RAPD分析发现136 个DNA片段中有22个发生基因分离，但由于研究方法的局限，不能确定是否发生基因重组。

Whole protein patterns during early stage of gynogenesis were first studiedthrough 2D electrophoresis. 11 specific protein dots were found, among which3(A1 ～A3 )were suggested to be the kind of inverse function factors which suppressgenes activating megagamete division, 8 (Bl～B8)were suggested to be closelyrelated with megagamet division activation.

通过双向电泳技术研究了黄瓜雌核发育早期的特异蛋白质表达，并发现了11个特异多肽点，其中3个(Al～A3)可能是开启分裂基因表达的一类反式作用因子，起抑制该基因表达作用。8个(B1～B8)可能是启动雌配子分裂密切相关的基因表达产物。

To induce diploid gynogenesis in summer flounder, eggs were fertilized with heterogenous cryopreservative sperm of Lateolabrax japonicas , which was irradiated with UV ray to be genetically inactivated, and cold shock was used to prevent extrusion of the second polar body.

中文摘要：用冷冻保存的花鲈精子作为异源精子，采用紫外线对精子进行照射使其遗传物质失活，然后与卵子进行"授精"，可以刺激犬齿牙鲆鱼卵进行雌核发育，在受精后一定时间采用冷休克处理"授精"卵，抑制第二极体排出成功获得了犬齿牙鲆雌核发育二倍体鱼苗。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

The paper summarizes studies of in vitro inducement of haploids in cucurbitaceae, including anther culture, in vitro gynogenesis culture and induction of haploid obtained by irradiated pollen. The factors affectting in vitro inducement such as material genetype, medium, pretreatment, megaspores development stage and others had significant effects on the embryoids inductivities.

重点对葫芦科植物离体诱导单倍体的研究进行综述，包括花药培养、离体雌核培养、辐射花粉诱导单倍体培养等在育种中的应用，以及供体基因型、培养基、预处理方式、胚囊发育时期等因素对离体诱导再生频率的影响。

To induce diploid gynogenesis in summer flounder, eggs were fertilized with heterogenous cryopreservative sperm of Lateolabrax japonicas , which was irradiated with UV ray to be genetically inactivated, and cold shock was used to prevent extrusion of the second polar body.

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
