发育不完全

The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.

猪是多胎动物，从猪卵巢上获得的卵母细胞数量虽然较多，但成熟度比较低；由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内，跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应；如果卵胞质成熟或活化程度不够，加之圆形未成熟精细胞成熟度比较差等原因，很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足，引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等，使ROSI显微受精失败。

Although an actie central nerous system is present by the eighth week of deelopment and a brainstem by the end of the first trimester (which could act as a rudimentary modulator of sensory information and motor actiity), Flower noted that the neocortex does not become a functional part of the neuraxis until at least mid-gestation when the thalamus (the major gateway for sensory input to the cerebrum) makes its first afferent contacts with the neocortex.

虽然在发育8周中枢神经系统即可有活性，在妊娠前三月结束时脑干具有活性（可充当感觉信息和运动功能的未完全发育的调制器），但是Flower表示，新皮质不会成为神经轴有功能的一部分，直到至少妊娠中期，丘脑（感觉传入大脑的主要通路）发挥其首先与新皮质系统输入联系的功能。

The results shows that the tapetal expanding abnormally occurs in dyadphase stage, microspore abortion occurs in the early of monokaryon stage, disaggregation in the end of monokaryon stage, only some spall of microspore is observed in monokaryon stage, the four cell walls also exist, the tapetal cells became completely vacuolated, almost filled the whole locule. vascular bundle of male sterile line anther vanish at mature pollen stage.

结果发现花药绒粘层在二分体时期发生异常，小孢子在单核前期开始败育，至单核后期完全解体，花药发育后期不育系药腔中只观察到少量的小孢子残体，花药壁的四层细胞依然存在，绒粘层细胞已经彻底液泡化，占据了药腔的整个空间，花粉成熟期不育系花药维管束消失。

Following chemical activation, blastocysts rate of the treated oocytes was similar to untreated oocytes.8 Following fertilization, however, few oocytes inhibited with CHX developed into morulae/blastocysts, due to a high incidence of polyspermy.9 Cortical granule migration occurred during inhibition, but CHX inhibition impaired CG migration, significantly no oocytes inhibited by CHX completed CG migration after maturation.10 CHX inhibition had no effects onα-microtubles and microfilaments of goat oocytes.

抑制24h转为正常培养24h，不影响卵母细胞的成熟和孤雌激活能力，并且CHX抑制后再成熟的卵母细胞经孤雌激活发育到囊胚的比例与对照组卵母细胞相似。8、体外受精后，CHX抑制后再成熟卵母细胞的多精受精现象显著增加，发育到桑椹胚/囊胚的比例显著低于对照组。9、CHX抑制过程中皮质颗粒仍能发生迁移，但是CHX抑制会对皮质颗粒的迁移造成不可恢复的损伤，使再成熟的卵母细胞内皮质颗粒不能完全迁移。10、CHX抑制对山羊卵母细胞α-微管和微丝都没有影响，无论是抑制后处于生发泡期的卵母细胞，还是抑制后再成熟的卵母细胞，微管和微丝的分布都与对照卵母细胞相似。
