Sequence alignment results of Izumo1 DNA and full-length cDNA. a Sequence alignment results of Izumo1 DNA. Rambouillet sheep-DNA means Izumo1 DNA sequence of Rambouillet sheep (GenBank:NC_040265.1); Small Tail Han sheep-DNA means Izumo1 DNA sequence of Small Tail Han sheep, which was we cloned [17]; Sunit sheep-DNA means Izumo1 DNA sequence of Sunit sheep, which was we cloned [17]. Texel sheep-Oar3.1-DNA means Izumo1 DNA sequence of Texel sheep (Oar_v3.1: NC_019471.1); Texel sheep-Oar4.0-DNA means Izumo1 DNA sequence of Texel sheep (Oar_v4.0: NC_019471.2). b Sequence comparison results of exon 2 of Izumo1 cDNA. W sheep-cDNA means Izumo1 cDNA sequence from unKnow breed of sheep (GenBank:NM_001164492.1); Small Tail Han sheep-cDNA means Izumo1 cDNA sequence that we cloned in this research; Texel sheep-Oar3.1-cDNA means CDS of Izumo1 in Texel Sheep (Ensembl: ENSOART00000013198.1 IZUMO1–201 cDNA:protein_coding). c Part of the Izumo1 DNA of Small Tail Han sheep. The red box reprent the 57 bp new sequence in Small Tail Han sheep DNA which is not exit in Texel sheep; The green box reprent the 35 bp new sequence which belong to Exon2 of Izumo1 in Small Tail Han sheep. d Part of the Izumo1 DNA of Texel sheep; e Sequence alignment of termination codon region of Izumo1 cDNA. The left tag is the same as (b)
