| 1. | Effect of wasp symbionts wolbachia on the thelytokous parthenogenesis of trichogramma cacoeciae 对寄主产雌孤雌生殖行为的影响 |
| 2. | But are cloned cells ? or those generated through parthenogenesis ? normal 然而,复制的细胞(或以孤雌生殖方式产生的细胞)正常吗? |
| 3. | The application study on spring wheat breeding of parthenogenesis induced by chemicals 化学药剂诱导孤雌生殖在春小麦育种中的应用研究 |
| 4. | Studies and application parthenogenesis breeding of dwarf and abortive wheat induced by chemical 化学诱导矮败小麦孤雌生殖育种的研究与应用 |
| 5. | Two diploid gametes may fuse to give a tetraploid zygote , or gamete may develop directly by parthenogenesis 两个二倍体配子融合可能产生一个四倍体合子,这样的配子也可以通过孤雌生殖直接发育而来。 |
| 6. | We are eager for the day when we will be able to offer therapeutic cloning or cell therapy arising from parthenogenesis to sick patients 我们渴望有这麽一天,可以利用复制疗法或孤雌生殖的细胞疗法来治疗病人。 |
| 7. | The results show that the blastomere nuclei of ? xenopus laevis induces the parthenogenesis of unfertilized egg in ? bufo raddei 根据实验分析认为,非洲爪蟾的胚胎细胞核进入花背蟾蜍成熟卵后,引起的是花背蟾蜍的单性发育。 |
| 8. | In our parthenogenesis experiments , we exposed 22 eggs to chemicals that changed the concentration of charged atoms called ions inside the cells 在我们的孤雌生殖实验当中,我们把22颗卵子养在可改变细胞内离子浓度的化学药剂里。 |
| 9. | Two kinds of compound ( nonylphenol and octyl phenol ) can not only decrease the number of the reproduction , but also affect the parthenogenesis of daphnia magua straus 结果表明,急性毒性较大的烷基酚,例如4 -辛基酚和4 -壬基酚对大型蚤的生殖毒性产生影响。 |
| 10. | These bacteria are transmitted through the cytoplasm of eggs and have evolved various mechanisms for manipulating reproduction of their hosts , including cytoplasimic incompatibility ( ci ) , parthenogenesis , feminization , male killing , fecundity or fertility modifying etc . wolbachia are common and widespread bacteria infecting 17 % insect population , 17 crustacean species , mites and many nematodes 这些共生菌通过母系遗传参与调控寄主的多种生殖活动,包括细胞质不亲和现象、诱导孤雌生殖现象、雌性化、雄性致死以及调节寄主生殖力等。 wolbachia的分布十分广泛,目前已经发现在超过17的昆虫种群以及17种甲壳纲动物、螨虫、线虫体内发现了它的存在。 |
