本文对粗面内质网在蛋白体形成中的作用，淀粉质体被膜在淀粉质体增殖中的作用，淀粉胚乳细胞的核质关系，植物PCD中细胞核的变化，以及质膜内陷、内质网、Ca〓和磷酸水解酶在胚乳发育中的作用等进行了讨论。

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。

Among these features are: absence of the nuclear rotation and development of the centriolar complex and the initial region of the axoneme in a position directly perpendicular to the basal pole of the nucleus and presence of numerous thick anchoring fibrils connecting the proximal centriole and the proximal part of the distal centriole to the nucleus.

We propose that APP may have the function of anchor to catch ANKS1B to prevent into the nucleus, the cleavage of AICD is very important to the translocation of ANKS1B, and AICD and ANKS1B may co-transport into nucleus.

推测APP蛋白似乎可以抓住ANKS1B，避免ANKS1B进入细胞核，所以AICD的切割对於ANKS1B的转位很重要；也许AICD会和ANKS1B一起进入细胞核。

ConclusionThe formation and diminishment of the manchette is in step with the condensation and elongation of the nucleus of the spermatid. Both the structural and positional changes of the manchette coincide with the changes of the nucleus. These results imply that manchette might play an important role in mouse spermiogenesis.

Manchette结构的形成和消失与精子细胞核的浓缩及延伸同步，其形态变化和位置改变与精子细胞核的形态学变化相吻合，在小鼠精子细胞变态成形过程中具有重要意义。
