Evolutionary placement of Xanthomonadales based on conserved protein signature sequences
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Xanthomonadales comprises one of the largest phytopathogenic bacterial groups, and is currently classified within the gamma-proteobacteria. However, the phylogenetic placement of this group is not clearly resolved, and the ...
Replacement of the arginine biosynthesis operon in Xanthomonadales by ateral gene transfer
(SPRINGER, 2008)
The role of lateral gene transfer (LGT) in prokaryotes has been shown to rapidly change the genome content, providing new gene tools for environmental adaptation. Features related to pathogenesis and resistance to strong ...
NAD Biosynthesis Evolution in Bacteria: Lateral Gene Transfer of Kynurenine Pathway in Xanthomonadales and Flavobacteriales
(OXFORD UNIV PRESS, 2009)
The biosynthesis of quinolinate, the de novo precursor of nicotinamide adenine dinucleotide (NAD), may be performed by two distinct pathways, namely, the bacterial aspartate (aspartate-to-quinolinate) and the eukaryotic ...
Laterally transferred genomic islands in Xanthomonadales related to pathogenicity and primary metabolism
(BLACKWELL PUBLISHING, 2008)
Lateral gene transfer (LGT) is considered as one of the drivers in bacterial genome evolution, usually associated with increased fitness and/or changes in behavior, especially if one considers pathogenic vs. non-pathogenic ...
Different patterns of evolution for duplicated DNA repair genes in bacteria of the Xanthomonadales group
(2004-08-27)
Abstract
Background
DNA repair genes encode proteins that protect organisms against genetic damage generated by environmental agents and by-products of cell metabolism. The ...

Detection of the bacterium, Xylella fastidiosa, in saliva of glassy-winged sharpshooter, Homalodisca vitripennis
(UNIV ARIZONA, 2008)
Homalodisca vitripennis ( Germar) ( Hemiptera: Cicadellidae), the glassy- winged sharpshooter, is one of the most important vectors of the bacterium, Xylella fastidiosa subsp. piercei ( Xanthomonadales: Xanthomonadaceae) ...
