| Abstract: | Using transmission electron and fluorescent microscopes, Mycoplasma-like organisms (MLOs) were found in phloem cells of stems and leaves of Ammobium alatum. The diameter of these organisms ranged from 0.12–0.73 μm and averaged 0.4 μm. Symptoms induced by MLOs included chlorosis and reddening of leaves and winged stems, plant stunting and flower phyllody. This is the first report of MLOs associated with disease symptoms in A. alatum. |
