摘要:

本研究旨在对影响鸡与鹌鹑杂交早期胚胎发育及性分化4个基因的表达进行检测,初步判定其对杂交种胚胎性别分化和早期死亡可能起到的作用。研究选取杂交早期胚胎发育不同时间点(72、78、84、90、96、102、108、114、120、144、168和192 h)活胚全胚,在鉴定杂交种早期胚胎性别的基础上,采用Real-time PCR方法检测雌雄杂交早期胚胎发育过程中不同时间点性分化相关基因的表达。结果表明,鸡与鹌鹑杂交胚胎中-HSDER基因雌性的表达量总体显著高于雄性。-HSD表达量雄性胚胎在72 h最低,雌性和雄性杂交胚胎96 h表达量最高。在90 h内雌、雄性杂交胚胎P-450c17 基因表达水平较高,在78 h达到最高峰,在90 h内的各个时间点雌性与雄性比较差异极显著(P<0.01)。杂交胚胎P-450arom基因在雌性可以检测到表达,但是雄性不能检测到表达。在杂交胚胎发育早期ER的表达有2个时间点是高峰,分别在72和108 h。

Abstract:

This study aimed to detect expression of genes related to early embryonic development and sexual differentiation in the chicken-quail hybrids.First,the whole embryos were collected during the hybrid early embryonic development at different times(72,78,84,90,96,102,108,114,120,144,168 and 192 h).Then,based on the identification of early hybrid embryo sexes,Real-time PCR method was used to detect the expressions of sex differentiation associated genes (-HSDP-450c17,P-450arom and ER) during the embryonic development of male and female hybrids at different times.The results showed that in chicken-quail hybrid embryos,both of -HSD and ER genes expression in females were generally significantly higher than that in males.The lowest expression of -HSD occured at 72 h in male,while the highest expression occurred at 96 h in female and male embryos.Within 90 h,the gene expression level of the male and female hybrid embryos P-450c17 was higher,peaking at 78 h,and there were significantly differences(P<0.01) in females and males at each time point within 90 h.P-450arom hybrid embryo gene expression could be detected in females,but the expression of the males could not be detected.There were two peaks,respectively,at 72 and 108 h expression of ER gene in early hybrid embryonic development.
