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.
