Predicted ATP-binding cassette systems in the phytopathogenic mollicute Spiroplasma kunkelii

Molecular Genetics and Genomics, 2004
Spiroplasma kunkelii is a cell wall-free, helical, and motile mycoplasma-like organism that causes corn stunt disease in maize. The bacterium has a compact genome with a gene set approaching the minimal complement necessary for cellular life and pathogenesis. A set of 21 ATP-binding cassette (ABC) domains was identified during the annotation of a draft

Exitianus obscurinervis (Hemiptera: Cicadellidae), a New Experimental Vector of Spiroplasma kunkelii

Journal of Economic Entomology, 2011
"Corn stunt" caused by the mollicute Spiroplasma kunkelii (Whitcomb) is potentially one of the most severe diseases affecting the corn (Zea mays L.) crop in the Americas, and the leafhopper Dalbulus maidis (DeLong & Wolcott) is considered its most important vector.

Sequence Analysis of Spiroplasma phoeniceum and Spiroplasma kunkelii Spiralin Genes and Comparison with Other Spiralin Genes

Current Microbiology, 1997
The spiralin genes from two phytopathogenic spiroplasmas, Spiroplasma phoeniceum and Spiroplasma kunkelii, were amplified by PCR, cloned, and sequenced. Comparison of the amino acid sequences of the five spiralins analyzed to date confirm that the spiralins have a general amphiphilic character and possess a conserved lipoprotein signal peptide. It also

Identification and characterization of traE genes of Spiroplasma kunkelii

Gene, 2004
Four traE homologs, designated traE1, traE2, traE3 and traE4, were identified and amplified from the genome of the leafhopper-transmitted corn stunt pathogen Spiroplasma kunkelii and were predicted to encode membrane-bound adenine tri-phosphatases (ATPases). Deduced proteins of all traE genes have 62.3% to 89.9% similarity to the conserved VirB4 domain

Gene content and organization of an 85-kb DNA segment from the genome of the phytopathogenic mollicute Spiroplasma kunkelii

Molecular Genetics and Genomics, 2003
Spiroplasma kunkelii, the causative agent of corn stunt disease in maize (Zea maysL.), is a helical, cell wall-less prokaryote assigned to the class Mollicutes. As part of a project to sequence the entire S. kunkelii genome, we analyzed an 85-kb DNA segment from the pathogenic strain CR2-3x. This genome segment contains 101 ORFs and two tRNA genes. The

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.

New Developments in the Culture of Spiroplasma Kunkelii, The Corn Stunt Spiroplasma

1988
Spiroplasma kunkelii, the corn stunt spiroplasma (CSS), is one of several Spiroplasma species that have been isolated from the plant habitat. Of those proven or suspected to be plant pathogenic, S. kunkelii is the most fastidious in its requirements for growth in vitro. S.
