Temporal and spatial expression pattern of gibel carp pou2 during embryogenesis was investigated by RT-PCR and whole-mount in situ hybridization. RT-PCR result indicates that there is maternal transcript of gibel carp pou2 in early embryos and the zygotic pou2 transcript is abundantly expressed from blastula stage. Large amount of pou2 transcript is detected at both 50% and 90% epiboly stages. At 100% epiboly stage, however, the pou2 transcript reduces rapidly and disappears at the later embryogenesis. Whole-mount in situ hybridization shows that the maternal transcript ubiquitously exists in all blastomere cells.

我们用RT-PCR和整体原位杂交的方法研究了银鲫pou2基因在胚胎发育过程中的时空表达图式RT-PCR结果显示，银鲫pou2基因有母源转录本，其合子基因在高囊胚期强烈表达，在50%下包期和90%下包期也有高量的转录本，但在100%下包期表达量急剧降低，至体节期时已经完全检测不到其转录本胚胎整体原位杂交结果显示其母源转录本在所有的胚盘细胞中。
