Transfer of an exogenous gene into cells via TSGAMAP. a DNA-coated gold particles shot at an onion leaf with TSGAMAP. The circles indicate regions with the gold particles. Pressures used to shoot the particles (“300 psi” and “435 psi”) are also indicated. The picture was taken after the gold particles on the leaf surface were wiped. Scale bar = 5 mm. b GFP signals detected in an onion epidermal cell (left panel). A bright-field image for the same cell (right) is presented as a control. Scale bar = 50 μm. c A lettuce leaf shot with TSGAMAP. The pressure used was 175 psi. The circle indicates the shot region. Scale bar = 5 mm. d GFP signals detected in a lettuce epidermal cell (left panel). A bright-field image for the same cell (right) is presented as a control. Scale bar = 25 μm
