Abstract:

[Objective] This study on the Arctic fox leptin gene structure, and through PCR-SSCP method to find the impact performance of arctic foxes loci. [Methods] Data used SignalP 3.0 Server, ClustalX1.83, Mega4.0, Promoter predictions, TMHM2.0, ProtComp-v6.0 software and SPSS13.0 software such as biology to complete the analysis; [Results] arctic fox and dog genetic the distance is the latest, OB gene it may be a secreted protein with a signal peptide sequence of a great possibility, AB genotype of the individual body weight, abdominal circumference, hides length and AA, BB-type individual's body weight, abdominal circumference, Long hides significant difference (P <0.01), AB genotype of the body length than the AA, BB-type of individual differences in body length tended to significantly (P <0.3), AB-type genes of individual hairs length and AA, BB-type individuals The long hairs were significantly impact the trend P <0.2 [Conclusion] showed that leptin gene mutations lead to the genotype of the body weight, abdominal circumference, hides long had a significant impact on most (P <0.01).
