查询词典 gynogenesis

The results indicated, that the curves of hatching rate and normal diploid larva output showed a single peak, with the highest point at 3.4 τ0, corresponding to metaphase of the first mitotic division, the results were obtained irrespective of the different pre-treatment water temperatures, thus confirming the veracity of measuring heat-shock timing by τ0 and the wild applicability of this method in cyprinid and also suggesting a new way to the operations of induced gynogenesis in related fish.

结果提示了以τ0单位度量热休克处理时机的准确性以及该优化方法在鲤科鱼类雌核诱导操作中的通用性，从而为相关鱼类的雌核发育操作提供了有价值的资料。

F〓 of transgenic allotetraploid fish containing"all-fish"transgene——pCAgcGHc was obtained respectively by inbreeding and gynogenesis. Positive rate of pCAgcGHc detected by PCR was 90％ in F〓 of transgenic allotetraploid fish produced by inbreeding, while most F〓 of transgenic allotetraploid fish produced by gynogenesis showed diploidy measured by flow cytometer. The results above imply that developing the pure line of transgenic allotetraploid fish through inbreeding is feasible, but the operation should be modified if gynogenesis is introduced.

采用近交和雌核发育方法培育出转pCAgcGHc基因异源四倍体鲫鲤F〓代，通过PCR检测，外源基因pCAgcGHc在近交转pCAgcGHc基因异源四倍体鲫鲤F〓中的整合率为90％，而流式细胞技术检测雌核发育转pCAgcGHc基因异源四倍体鲫鲤F〓的倍性多为二倍体，说明通过近交筛选转基因异源四倍体鲫鲤纯系的方法是可行的，但是通过雌核发育来筛选转基因异源四倍体鲫鲤纯系还要就方法上进一步的改进。
