Abstract

Abstract: The BoPDIL1-2 gene was isolated from the stigma of ornamental kale(Brassica oleracea var. acephala) S_13-bS_13-b homozygotes by RT-PCR and RACE. The BoPDIL1-2 coding region sequence was inserted into the prokaryotic expression vector pET-14b and transformed into the E.coli cell for purification.We prepared the polyclonal antibodies against recombinant BoPDIL1-2 through immune mouse. The expression level of BoPDIL1-2 in the various tissue anddifferent developmental stigmas were detected by Western blot. The deduced amino acid sequence of BoPDIL1-2 shared 97.3% and 85.5% identity with Brassica napus BnPDIL1-2 and Arabidopsis thaliana AtPDIL1-2, respectively. SDS-PAGE results showed that the recombinant BoPDIL1-2 fusion protein about 58 kDa was induced by IPTG.Western blot results revealed BoPDIL1-2 wasspecifically expressed inthe stigma,the expression of BoPDIL1-2 was lower in the early stage of stigma, while it was higher in the stigma at theflowering stage.

Key words: Brassica oleracea var. acephala, PDIL1-2, prokaryotic expression, polyclonal antibody, expression analysis
