Mx haplotypes identified in the 9 elite lines as determined by 6 promoter, and 34 exon SNP.

1Denotes SNP that were not tested within the elite lines, not segregating in the elite lines.
MxP-# denotes SNP in the promoter regions 400 bp upstream of RNA transcription initiation which includes the Mx ISRE. Numbers indicates nt position upstream of RNA initiation.
Mx5U# denotes SNP in the 5′ untranslated region. Number indicates nt position within the mRNA transcript.
MxCDS# denotes SNP in the coding region of Mx. Number indicates nt position from the beginning of the start codon.
*Denotes SNP not found within the 9 elite lines examined in this study but have been previously been reported.

1. 表示未在优良品系中检测、且在优良品系中不发生分离的单核苷酸多态性（Single Nucleotide Polymorphism，SNP）
MxP-# 表示位于RNA转录起始位点上游400 bp（碱基对）的启动子区域（包含Mx ISRE）内的单核苷酸多态性，其中数字代表RNA转录起始位点上游的核苷酸（nt）位置
Mx5U# 表示位于5′非翻译区（5′UTR）内的单核苷酸多态性，数字代表mRNA转录本内的核苷酸位置
MxCDS# 表示Mx基因编码区内的单核苷酸多态性，数字代表从起始密码子起始位置开始计算的核苷酸位置
* 表示本研究检测的9个优良品系中未检出，但此前已有报道的单核苷酸多态性
本研究通过6个启动子区域单核苷酸多态性与34个外显子单核苷酸多态性，在9个优良品系中鉴定得到Mx基因单倍型
