Methods
The transformation of gfp gene into the D. pseudosalina was evaluated by three strains including EHA101, GV3301 and GV3850 of A. tumefaciens. The integrating and expression of gfp gene were determined by PCR, RT-PCR, Q-PCR and SDS-PAGE analyses.
Results
The T-DNA of pCAMBIA1304 plasmid was successfully integrated into the genome of the microalgal cells. Although all of the strains were able to transform the algal cells, GV3301 possessed higher potential to transform the microalgal cells in comparison to EHA101 and GV3850 strains. Moreover, the stability of gfp gene was successfully established during a course of two months period in the microalgal genome.
