New transgenic techniques using bioactive beads that have entrapped the DNA-lipofectin complex have been developed for introducing exogenous genes.The green fluorescence protein-expressing tobacco BY-2 protoplasts (left, phase contrast images; right, fluorescence images) resulted in fourfold higher transformation efficiency than that by the conventional method.
