Description

Micrograph of a semi-thick (1-2 µm) section of an infected maize leaf, with silver-enhanced immunogold labeling, that shows dark staining of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) aggregates in phloem tissue (asterisk). The section was counter stained with toluidine blue. CIL:12591, from the same image group, is an unlabeled version of this image. 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.
