A pair of primers based on conservative sequences of Drosophila melanogaster was designed to amplify the p53 gene. The fragment with 1156 base pair was obtained and sequenced. The percent identity between others' and ours' was 99.4%, with the other biological sequence of p53 existing some differences.

This suggests that CaHIRA plays a role in the early embryo development and the late stages. The different expression characters of hira gene in these fish species may be related to the different reproduction models. The research on Drosophila has indicated hira gene related to sperm nucleus decondensation during fertilization. The high expression of hira gene before fertilization is prepared for the sperm nucleus decondensation and the formation of male prenucleus because colored crucian carp is bisexual reproduction. However, the sperm nucleus is not decondensated during the fertilization and is only to activate egg nucleus in gynogenetic gibel carp.

在彩鲫中，从未受精卵到胚胎发育的各个时期均可检测到表达，但表达量发生明显变化，受精后表达量迅速下降，直到原肠胚期表达量有所上升，并一直保持到出苗。hira基因在两亲缘种成熟卵子受精前后表达情况不同，可能与两种鱼不同的生殖方式有关。
