摘要: 利用半定量RT-PCR方法,对MyoT基因在白来航鸡7种不同组织(心、肝、脾、肺、肾、脑和肌肉)中的表达谱进行研究。结果表明,MyoT基因只在心脏和肌肉中表达。克隆得到了鸡MyoT基因的部分片段,发现外显子10存在A/G转换,利用PCR-Hin6Ⅰ-RFLP方法对其在12个中国地方鸡种(白耳鸡、仙居鸡、大骨鸡、鹿苑鸡、固始鸡、斗鸡、乌骨鸡、油鸡、茶花鸡、萧山鸡、狼山和藏鸡)和1个外来鸡种(隐性白羽鸡)中的分布进行了研究。在藏鸡、隐性白羽鸡、杂交鸡(藏♂×隐♀)和75%血液藏鸡\[藏♂×(藏♂×隐♀)♀\]群体中进行了不同基因型与性状间的关联分析,结果表明,该SNP位点不同基因型与腿肌质量显著相关(P<0.05),与腿肌率和腿肌肉色极显著相关(P<0.01)。

Abstract: The semi-quantitative RT-PCR was performed to detect the expression pattern of chicken MyoT gene in 7 different tissues (heart, liver, spleen, lung, kidney, brain and muscle). The results showed that MyoT gene was expressed only in heart and muscle. Partial DNA sequence of chicken MyoT gene was cloned and a A/G transition was found in exon 10. Using PCR-Hin6Ⅰ-RFLP method, the A/G SNP locus was analyzed in 12 native chicken breeds (White Ear, Xianju, Dagu, Luyuan, Gushi, Game chickens, Silky Sooty, Beijing Fatty, Chahua, Xiaoshan, Langshan and Tibetan chicken) and 1 foreign breeds (Recessive White chicken). The association between different genotypes and carcass and meat quality traits was analyzed in Tibetan chicken, Recessive white, hybrid chicken (Tibetan♂×Recessive♀). The result of association analysis showed there were correlation between this SNP site and leg muscle weight (P<0.05), and significant correlation between this SNP site and leg muscle rate and meat colour (leg muscle) (P<0.01).
