Description
Electron micrograph of corn stunt spiroplasma (CSS) in the wall of the filter chamber (part of the alimentary canal) and in the hemolymph of a vector leafhopper D. gelbus. Note the mainly pleiomorphic forms in host cells and the filamentous/spiral forms in the hemolymph. CIL:19117, from the same image group, is identical to this image but contains labels. CSS is a wall-less procaryote that causes corn stunt disease and is biologically transmitted by some leafhopper species, e.g. Dalbulus maidis and D. gelbus (Hemiptera, Cicadellidae). Spiroplasma cells are limited by a unit membrane with no cell wall. They can be quasi-spherical, pleiomorphic or maintain a filamentous/spiral form. CSS multiplies in both plant and insect hosts and is transmitted with salivary secretions during feeding of the vector on new host plants. Additional images from this contributor are available in the Library.
