The gene regulating sequence of human collagen type Ⅰ is located at 5'end and first intron. The carriers of reporting gene was made, and the function of promoter, enhancer and inhibiter was examined in this study. On the basis of above work, MBP ectopic expression carriers were further built. The result laid a foundation for investigating the feasibility, and validity to specially express MBP gene of human nervous system, in tendon fibroblast.

人Ⅰ型胶原基因调节序列位于5'端和第一内含子，本研究构建了带报告基因的载体并检测了其启动子，增强子和减弱子的功能，以此为基础，进一步构建了MBP异位表达载体，为探索在神经系统少突胶质细胞特异表达的人脑髓鞘碱性蛋白MBP基因转至肌腱成纤维细胞表达的可行性和有效性奠定了基础。

The telomerase activity and it s subunit hTERT and hTR were observed in the SHEE and SHEEC.

SHEE 细胞和SHEEC 细胞均具有端粒酶活性，并均有hTERT 和hTR 表达。

The formation of silique dehsicence susceptibility was investigated in terms of water content, synthetic rate of ethylene, enzyme activity of exo polygalacturonase and end cellulase , cell alteration in dehiscence zone in silique and silique dehiscence susceptibility during silique development.

从油菜角果发育过程中角果含水量、乙烯合成速率、外切 PG 酶和内切纤维素酶活性，以及角果裂区切片观察等方面研究了角果开裂敏感性形成的原因⒚花后50d 的角果果柄端壳状果瓣和线状果瓣间的裂区薄壁细胞膨大，在高倍光学显微镜下可见胞间空隙开始形成⒚此前6d 内乙烯合成速率迅速上升并出现第二次合成高峰，与之同步发生外切 PG酶和内切纤维素酶活性急剧上升，而乙烯合成第二高峰出现于角果含水量低于80％以下⒚由此看来，角果失水引起乙烯合成第二高峰出现，从而导致水解酶活性上升，最终导致果瓣裂区薄壁细胞膨大，分离和胞间空隙形成及角果开裂敏感性产生

Two polar nuclei move to the micropylar end before sperm is released in a gap between the egg cell and central cell and subsequently taking off cytoplasm one after another. The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end.

精子释放前，两极核移向卵细胞的合点端；两精子释放于卵细胞与中央细胞的间隙后，先后脱去细胞质，然后分别移向卵核和极核，移向卵核的精核快于移向极核的精核；精核与两极核在向反足细胞团方向移动的过程中完成雌雄核融合。

The sperm nucleus moving to the egg nucleus runs faster than the one to the polar nuclei. It fuses with the polar nuclei that are moving towards the antipodal cells at the chalazal end, Images showed the fusion process of male and female nuclei and polyspermous fertilization.
