摘要 哺乳动物毛色是一个多基因控制的性状,Agouti是研究哺乳动物毛色发生的一个主要的候选基因。为研究Agouti基因在羊驼毛色发生过程中是否表达及其作用机理如何,本研究分别采用半定量RT-PCR技术和免疫组化技术对白色和棕色被毛成年羊驼皮肤组织进行研究。半定量RT-PCR显示,Agouti基因在白毛羊驼皮肤组织中高量表达,而在棕色毛羊驼皮肤组织中表达量较低;免疫组织化学显示,棕色被毛羊驼皮肤组织毛囊外结缔组织中有少量的Agouti阳性着色,白色羊驼毛囊内根鞘有大量的Agouti阳性着色,且形成了集中的Agouti特异性阳性着色圈。研究结果说明:Agouti基因在不同被毛羊驼皮肤组织中均有表达,在白色被毛羊驼真皮毛乳头表达的Agouti基因可能与白色被毛发生相关。
