Characterizing the Native Codon Usages of a Genome: An Axis Projection Approach
Codon usage can provide insights into the nature of the genes in a genome. Genes that are "native" to a genome (have not been recently acquired by horizontal transfer) range in codon usage from a l...
Conjugative Plasmid Transfer in Xylella fastidiosa Is Dependent on tra and trb Operon Functions
The insect-transmitted plant pathogen Xylella fastidiosa is capable of efficient horizontal gene transfer (HGT) and recombination. Natural transformation occurs at high rates in X. fastidiosa, but ...
Identification of genetic relationships and subspecies signatures in Xylella fastidiosa
The phytopathogenic bacterium Xylella fastidiosa was thought to be restricted to the Americas where it infects and kills numerous hosts. Its detection worldwide has been blooming since 2013 in Euro...
Origin of the bacterial SET domain genes: Vertical or horizontal?
The presence of Supressor of variegation-Enhanser of zeste-Trithorax (SET) domain genes in bacteria is a current paradigm for lateral genetic exchange between eukaryotes and prokaryotes. Because a ...
The Xylella fastidosa RTX operons: evidence for the evolution of protein mosaics through novel genetic exchanges
Xylella fastidiosa (Xf) is a gram negative bacterium inhabiting the plant vascular system. In most species this bacterium lives as a benign symbiote, but in several agriculturally important plants ...
