Figure 11.  Protection from TMV infection in transgenic tomato plants expressing TMV coat protein (left) vs. non transformed plants (right). A non transgenic plant tomato plant (right) and TMV CP-expressing plant (left) were challenged with a severe white or yellow strain of TMV (PV230 from ATCC). The tomato plants (L. esculentum cv. VF36) were photographed at 41 days post-inoculation with TMV. (Courtesy R.S. Nelson) BACK
