The results indicated that spindles, chromosomes and microfilaments of porcine oocytes at different stages were nonreversible damaged obviously followed exposion to freezing medium or vitrification, which may be the main reason affecting the maturation, fertilization and development of oocytes.
本研究结果表明，猪GV期和MⅡ期卵母细胞经冷冻保护剂处理或玻璃化冷冻保存后，都明显造成了纺锤体、染色体和微丝不可逆的损伤，可能是影响卵母细胞成熟、受精与发育的重要原因。

Three kinds of embryos' chromosome, including goat fertilization embryo, goat-goat cloned embryo and goat-rabbit cloned embryo were analyzed, The results showed that all of them have 60 chromosomes with same character, all were telocentric chromosome, besides the X-chromosome is the second larger telocentric chromosome.
经对超排获得的山羊受精胚、山羊同种克隆胚和羊-兔异种克隆胚的囊胚期胚胎染色体分析表明，三种来源的胚胎其染色体数目均为60条，且所有常染色体均为端部着丝点染色体，X染色体为第二大的端部着丝点染色体，说明山羊同种克隆胚和山羊-兔异种克隆胚均为山羊的核型，是供体细胞核在不同胞质中的重新编程的结果。4。

Dioecious monoecious, reproductive structures axillary, solitary. Pollen cones pedicellate, globose, with overlapping bracts at base; microsporophylls 6-14, shield-shaped, each with 4-9 radially arranged pollen sacs. Seed-bearing structures subsessile, with several overlapping bracts basically. Ovule erected, entrusted with disc-like embryophore. After fertilization, embryophore developed into fleshy, cup-like and red aril.
雌雄异株，球花单生于叶腋，有短柄；雄球花圆球形，基部覆瓦状排列的苞片，雄蕊6-14枚，盾状，花药4-9丝，辐射状排列；雌球花几乎无柄，基部有多数覆瓦状排列的苞片，胚珠直立，基部托以圆盘状的珠托，受精后珠托发育成肉质、杯状、红色的假种皮。

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。

ascogonium：产囊体
最佳答案: 有性生殖开始时,部分菌丝体的分枝分别形成多核、较小的雄器(antheridium)和较大的产囊体(ascogonium). 当雄器与产囊体上的受精丝(trichogyne)接触后,在接触点形成一个孔口,雄器中的许多细胞核就通过受精丝进入产囊体,与其中的细胞核配对形成...

fertilization：受精作用
粗丝期检控点(pachytene checkpoint)之分子作用机制减数分裂(meiosis)在真核生物有性繁殖中扮演决定性的角色,一次减数分裂包含了一次DNA复制,却有二次染色体分离,因此配子内的染色体数目得以减半,配合受精作用(fertilization)而维持子代染色体数
-
trichogyne：受精丝
雌器尖端有一小尖即受精丝(trichogyne). 雄器内的细胞质与核通过受精丝进入产囊器内,此时只进行质配,而细胞核则成对排列,并不结合. 同时,在两性器官下面生出许多纠缠在一起的菌丝将其包围,形成初期的闭囊壳. 壳内的产囊器膨大.
