The ability to achieve nuclear or chloroplast transformation in plants has been a long standing goal, especially in microalgae research. Over past years there has been only little success, but transient and stable nuclear transformation has been achieved in multiple species. Our newly developed method allows for relatively simple transformation of Cyanidioschizon merolae in both nuclear and chloroplast genome by means of homologous recombination between the genome and a transformation vector. The use of chloramphenicol resistance gene as the selectable marker allows for plate-based efficient selection of mutant colonies. Overall, the method allows the generation of mutant strains within 6 months.

To prepare the knockdown transformants of the Closterium peracerosum-strigosum-littorale (C. psl.) complex, particle bombardment was applied with a newly constructed vector (pSA0104) with an endogenous constitutive promoter fused to a DNA fragment corresponding to an antisense strand of a target gene. Using a hygromycin resistance gene (aph7”), hygromycin-resistant colonies were selected. After the second screening, integration of the vector into the genome was checked by PCR and the knockdown effect was evaluated by Western blotting using a specific antibody against the target protein.
