[Method] cDNA sequence of C4B gene was cloned with RACE-PCR method. Amino acid sequences in multiple species were aligned in GenBank, and a phylogenetic tree was constructed for homology analysis. [Result] C4B gene in Siji goose shared relatively high homology with chicken and quail; Siji goose C4B gene was expressed highly in liver and lung of adult geese and expressed lowly in epididymis, seminiferous duct, brain, kidney, testis, heart, oviduct and smal intestine. [Conclusion] In the present study, mRNA expression lev-el of C4B gene in different tissues and organs of Siji goose was determined by flu-orescence quantitative PCR, which provided basis for rapid diagnosis of specific an-imal diseases.展开更多
