An Analysis of the Genomic Variability of the Phytopathogenic Mollicute Spiroplasma kunkelii [PDF]

open access: yesPhytopathology®, 2013
Corn stunt disease has become a factor limiting maize production in some areas of the Americas in recent years. Although resistant maize genotypes have been developed in the past, this resistance has been unstable over time or in some geographical locations. To better understand disease components that could affect the stability of host resistance, we

Cryptic plasmid pSKU146 from the wall-less plant pathogen Spiroplasma kunkelii encodes an adhesin and components of a type IV translocation-related conjugation system [PDF]

open access: yesPlasmid, 2005
A cryptic plasmid of the wall-less plant pathogenic mollicute, Spiroplasma kunkelii CR2-3X, was cloned and its sequence analyzed. The 14,615 bp plasmid, designated pSKU146, has a nucleotide content of 28 mol% G + C, and contains 18 potential protein-coding regions (open reading frames, ORFs), of which six encode proteins that exhibit similarity to ...

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

open access: yesAnnals 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.

Response of maize hybrids to corn stuntdisease caused by <i>Spiroplasma kunkelii </i>in the Argentine Northwest (NOA) – 2023-2024 growing season

open access: yesAgriScientia
Corn stunt disease (CS) is caused by Spiroplasma kunkelii, Maize rayado fino virus (MRFV), Maize bushy stunt phytoplasma (MBSP) and Maize striate mosaic virus (MSMV) and transmitted by Dalbulus maidis. During 2023–2024, it severely affected corn production in Argentina, with losses of 20 %.

A genome sequence survey of the mollicute corn stunt spiroplasmaSpiroplasma kunkelii [PDF]

open access: yesFEMS Microbiology Letters, 2002
The mollicute corn stunt spiroplasma (Spiroplasma kunkelii) is a leafhopper-transmitted pathogen of maize. Sequencing of the approximately 1.6-Mb genome of S. kunkelii was initiated to aid understanding the genetic basis of spiroplasma interactions with their plant and leafhopper hosts.

Phylogenetic positions of ‘Candidatus Phytoplasma asteris' and Spiroplasma kunkelii as inferred from multiple sets of concatenated core housekeeping proteins [PDF]

open access: yesInternational Journal of Systematic and Evolutionary Microbiology, 2005
Phytopathogenic mollicutes, which include spiroplasmas and phytoplasmas, are cell wall-less bacteria that parasitize plant hosts and insect vectors. Knowledge of the evolution of these agents is important in understanding their biology. The availability of the first complete phytoplasma and several partial spiroplasma and phytoplasma genome sequences ...
