Brote Grande, A New Phytoplasma Associated Disease of Chile Peppers in the Desert Southwest

Fig. 3. Electron microscopy of vascular tissue from healthy and brote grande affected plants. Cross sections of vascular tissue from the base of leaves were fixed, embedded, sectioned and stained as described in the methods section. Panels A and B are low magnification images from healthy and symptomatic tissue, respectively. Scale bars indicate 5 µm and 0.5 µm in low and high magnification photomicrographs, respectively. The arrow in panel B points to a phloem sieve element containing numerous bacteria like bodies. Panel C is a high magnification image of the bacteria like bodies present in the phloem sieve elements of symptomatic tissues.
