title: Cloning and sequencing of adhesion protein gene of Trichomonas gallinae from pigeon.
abstract: The adhesion protein (AP) gene of Trichomonas gallinae from pigeon was cloned and sequenced. The first-strand cDNA of the AP gene of T. gallinae from pigeon was amplified by reverse transcription polymerase chain reaction (RT-PCR) with total RNA extracting kit and cloned in the vector pMD18-T. The recombinant plasmid was identified by PCR and restriction endonuclease, and the positive clone was sequenced and analysed by comparing the sequence similarity with other sequences in the GenBank. The AP gene of T. gallinae had a length of 1032bp, which contained a complete open reading frame (ORF) of 930bp long, coding for 309 amino acids. The sequence analysis revealed that the homology with three AP genes of Trichomonas vaginalis (i.e., TVU87096, TVU87097 and TVU87098) was 94.2%, 92.6% and 92.0%, respectively. It is concluded that the successfully cloned AP gene from T. gallinae will provide the basis for the expression of the AP gene in prokaryotic and eukaryotic cells and the preparation of its recombinant protein.
