摘要
TASlR2基因是味觉受体I型家族的第2个成员。本试验采集新西兰兔共417个样本，采用PCR产物直接测序法检测了家兔TASlR2基因上的单核苷酸多态性（SNPs），分析不同基因型与日龄重的遗传效应。研究结果如下：家兔TASlR2基因exon6的c．1581G〉A突变基因型AA极显著影响40日龄、56日龄和84日龄家兔的体重以及35～84日龄的平均日增重（P〈0．01），可考虑将TASlR2基因作为家兔生产性状的候选基因，以期为家兔生长性状标记辅助选择提供理论依据。
TAS1R2 gene is the second member from taste receptor type I family. In this study, a total of 417 New Zealand rabbits were collected to analyze the single nucleotide polymorphism of rabbit TAS1R2 by direct sequencing method. The results as follows： genotype AA from the c.1581 G〉A mutation of rabbit TAS1R2 gene in exon 6 had significant effect on rabbit＇s 40-days weight, 56-days weight, 84-days weight and 35-84-days average daily gain （P〈0.01）. So TAS1R2 gene was considered to candidate gene of rabbit＇s production traits, it might be to provide theoretical ba- sis for auxiliary selection for growth trait markers in rabbits.
