Abstract: The total RNA was extracted from the pituitary of Zi goose, and the cDNA of the FSHα was amplified by RT-PCR. The amplified FSHα gene is 396 bp in length. The FSHα gene was cloned into the vector pMD18-T. The positive clones were verified and sequenced. The nucleotide sequence and deduced amino acid sequence were compared with homologous sequences from available species including chicken, quail, turkey, mouse, sheep, cattle, et al. Sequence alignment showed that FSHα gene in these species were highly conservative. FSHα gene had the highest homology of 95.9% with chicken, quail and turkey in nucleotide, and had the highest homology of 97.5% with chicken, quail and turkey in amino acids. Then the clones of FSHα gene were inserted into pET-32a (+) prokaryotic expression vector.
