Physical and genetic map of the Spiroplasma kunkelii CR2-3x chromosome

Canadian Journal of Microbiology, 2006
Spiroplasma kunkelii (class Mollicutes) is the characteristically helical, wall-less bacterium that causes corn stunt disease. A combination of restriction enzyme analysis, pulsed-field gel electrophoresis (PFGE), and Southern hybridization analysis was used to construct a physical and genetic map of the S. kunkelii CR2-3x chromosome.

Infection and replication sites of Spiroplasma kunkelii (Class: Mollicutes) in midgut and Malpighian tubules of the leafhopper Dalbulus maidis

Journal of Invertebrate Pathology, 2003
Spiroplasma kunkelii distribution and infection mechanisms in the intestines and Malpighian tubules of Dalbulus maidis were investigated by transmission electron microscopy. Spiroplasmas were found between microvilli and in endocytic vesicles of the midgut epithelium.

Cell Division Gene Cluster in Spiroplasma kunkelii: Functional Characterization of ftsZ and the First Report of ftsA in Mollicutes

DNA and Cell Biology, 2004
Spiroplasma kunkelii is a helical, wall-less bacterium that causes corn stunt disease. In adaptation to its phloem-inhabiting parasitic lifestyle, the bacterium has undergone a reductive evolutionary process and, as a result, possesses a compact genome with a gene set approaching the minimal complement necessary for multiplication and pathogenesis.

Movement and Multiplication ofSpiroplasma kunkeliiin Corn

Phytopathology, 1995
After the introduction of Spiroplasma kunkelii into the leaves of corn (Zea mays) seedlings by inoculative corn leafhoppers (Dalbulus maidis), the pathogen was detected by enzyme-linked immunosorbent assay. Spiroplasmas were detected in leaves 14 days after exposure to inoculative leafhoppers (as much as 2 weeks before symptoms appeared) and in roots ...

Field overwintering biology of Spiroplasma kunkelii (Mycoplasmatales: Spiroplasmataceae) and its vector Dalbulus maidis (Hemiptera: Cicadellidae)

Annals of Applied Biology, 2007
AbstractWe studied the corn stunt spiroplasma (CSS), Spiroplasma kunkelii (Mycoplasmatales: Spiroplasmataceae) and its vector the corn leafhopper Dalbulus maidis (Hemiptera: Cicadellidae) under field conditions in Mexico. We surveyed for the presence of CSS in D.

Species-Specific and Cross-Reactive Monoclonal Antibodies to the Plant-Pathogenic SpiroplasmasSpiroplasma citriandS. kunkelii

Phytopathology, 1989
Forty of the monoclonal antibodies recognized antigenic sites found on Ig-trapped intact spiroplasmas and spiroplasma membrane preparations, whereas the remaining six monoclonal antibodies reacted only with disrupted spiroplasma cells in indirect ELISA. At least 17 different antigenic sites were defined by the 46 monoclonal antibodies.

Association of the Pathogen Spiroplasma kunkelii with Corn Stunt Symptoms in Oklahoma, Kansas, Missouri, Arkansas, Nebraska, South Dakota, New York, Wisconsin, Minnesota, Indiana, and Alabama During the 2024 Growing Season

Plant Health Progress
Corn stunt is one of the most significant corn diseases in the Neotropics, leading to severe plant stunting and substantial yield losses. Although four pathogens have been found either singly or in combination in infected plants in the Americas, corn stunt spiroplasma ( Spiroplasma kunkelii) has been the most predominant pathogen associated with the ...
