The primers were designed according to the reference Sedirea japonica AP1-like gene from NC-BI. The SeAP1-like gene was amplified from the scape of Sedirea japonica petal by RT-PCR. The PCR product was sequenced. The sequencing result showed the target gene was 743 bp encoding 247 putative amino acid residues. The recombinant plasmid pCAMBIA1304-SeAP1 was obtained by identified by inser-ting the SeAP1-like gene into pCAMBIA1304 vector,and identified by PCR,double digestion. The results showed that the recombinant plasmid pCAMBIA1304-SeAP1 which contained the target gene was con-structed successfully. The structural domain of the SeAP1-like gene and the hydrophily of the protein ex-pressed by the SeAP1-like gene were analyzed,and the secondary structure of the protein expressed by the SeAP1-like gene was predicted. The results showed that SeAP1-like gene contained the MADS-box and K-box domain,belonged to MADS-box super family. This protein expressed by the SeAP1-like gene was hydro-philic and contained 57. 49% α-helical domains,6. 07% extended strand,36. 44% random coil.
