摘要: 摘要:对水貂黑素皮质素受体-4(MC4R)基因进行了克隆和序列分析,以期为进一步开展水貂MC4R基因与其肥胖性状的相关分析及基因定位等研究提供理论基础。首先采用特定引物对水貂MC4R基因进行PCR扩增、克隆和测序,然后用DNAMAN软件拼接MC4R基因全序列,并进行序列的同源性分析。试验获得水貂MC4R基因序列816 bp。水貂MC4R基因序列与同一种属的水獭的同源性最高,达96%,而与犬、狐、大熊猫、河马、野猪、山羊、人及小鼠这些哺乳动物的同源性在89%~95%之间,另外,与贝加尔湖海豹和加州海狮的同源性也较高,均为94%。本研究成功克隆了水貂的MC4R基因,结果表明,其在物种间具有较高的保守性。

Abstract: Abstract:Melanocortin receptor-4(MC4R)gene in mink was cloned and sequenced,in order to provide theoretical foundation for further research of the corelevantion of MC4R gene in mink and fat traits,and location. MC4R gene of mink was amplified using particular primers,cloned by polymerase chain reaction (PCR) method and sequenced,and spliced by using DNAMAN. The length of MC4R gene in mink was 816 bp. The sequences had been sent to GenBank and registered. Comparison of the fragment sequence with that of other mammal animals MC4R gene was carried out through BLAST in GenBank,the results showed that the homologies of the nucleotide sequence with river otter,dog,fox,panda,river horse,boar,goat,human and rat were 89% to 95%,MC4R gene of mink was successfully cloned in this study,indicating it was quite conservative among species.
