At 6 days post-first access to diseased plants, leafhopper intestines are stained with TUNEL (green), virus-rhodamine (red) and actin dye phalloidin-Alexa Fluor 647 carboxylic acid (blue), and then examined by confocal microscopy. TUNEL-positive signs could be detected in the limited areas of virus-infected intestines which are stained with actin dye in about 70% of viruliferous insects. Image is representative of three independent experiments with a total 30 leafhoppers analyzed. Wei et al.
