Abstract

OBJECTIVE

A chloroplast transgenic approach was assessed in order to produce a structural protein SPPV117 of sheep pox virus in Nicotiana tabacum for the future development of a plant-based subunit vaccine against sheep pox.

RESULTS

Two DNA constructs containing SPPV117 coding sequence under the control of chloroplast promoter and terminator of psbA gene or rrn promoter and rbcL terminator were designed and inserted into the chloroplast genome by a biolistic method. The transgenic plants were selected via PCR analysis. Northern and Western blot analysis showed expression of the transgene at transcriptional and translational levels, respectively. The recombinant protein accumulated to about 0.3% and 0.9% of total soluble protein in leaves when expressed from psbA and rrn promoter, respectively. Plant-produced SPPV117 protein was purified using metal affinity chromatography and the protein yield was 19.67  ±  1.25 µg g (FW) The serum of a sheep infected with the virus recognised the chloroplast-produced protein indicating that the protein retains its antigenic properties.

CONCLUSIONS

These results demonstrate that chloroplasts are a suitable system for the production of a candidate subunit vaccine against sheep pox.
