A Conjugative 38 kB Plasmid Is Present in Multiple Subspecies of Xylella fastidiosa
A similar to 38kB plasmid (pXF-RIV5) was present in the Riv5 strain of Xylella fastidiosa subsp. multiplex isolated from ornamental plum in southern California. The complete nucleotide sequence of ...
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 ...
Detection and Characterization of pXFSL21, a Novel Single-Copy Plasmid from Xylella fastidiosa Strain Stag's Leap
Xylella fastidiosa Strain Stag’s Leap, originally isolated from Napa Valley, California, is highly virulent in causing Pierce’s Disease (PD) of grapevine. Plasmids are extrachromosomal genetic elem...
Detection of a Single-Copy Plasmid, pXFSL21, in Xylella fastidiosa Strain Stag's Leap with Two Toxin-Antitoxin Systems Using Next-Generation Sequencing
Plasmids are important genetic elements contributing to bacterial evolution and environmental adaptation. Xylella fastidiosa is a nutritionally fastidious Gram-negative bacterium causing economical...
Functional Characterization of Replication and Stability Factors of an Incompatibility Group P-1 Plasmid from Xylella fastidiosa
Xylella fastidiosa strain riv11 harbors a 25-kbp plasmid (pXF-RIV11) belonging to the IncP-1 incompatibility group. Replication and stability factors of pXF-RIV11 were identified and used to constr...
Global features of sequences of bacterial chromosomes, plasmids and phages revealed by analysis of oligonucleotide usage patterns
Oligonucleotide frequencies were shown to be conserved signatures for bacterial genomes, however, the underlying constraints have yet not been resolved in detail. In this paper we analyzed oligonuc...
Identification of new protein-protein interactions involving the products of the chromosome- and plasmid-encoded type IV secretion loci of the phytopathogen Xanthomonas axonopodis pv. citri
The recently sequenced genome of the bacterial plant pathogen Xanthomonas axonopodis pv. citri contains two virB gene clusters, one on the chromosome and one on a 64-kb plasmid, each of which codes...
Intrinsic bent DNA sites in the chromosomal replication origin of Xylella fastidiosa 9a5c
The features of the nucleotide sequences in both replication and promoter regions have been investigated in many organisms. Intrinsically bent DNA sites associated with transcription have been desc...
Phylogeny of Replication Initiator Protein TrfA Reveals a Highly Divergent Clade of Incompatibility Group P1 Plasmids
Incompatibility group P1 (IncP-1) plasmid diversity was evaluated based on replication initiator protein (TrfA) phylogeny. A new and highly divergent clade was identified. Replication assays indica...
Plasmid pBP136 from Bordetella pertussis represents an ancestral form of IncP-1 beta plasmids without accessory mobile elements
The complete 41 268 bp nucleotide sequence of the IncP-1 beta plasmid pBP136 from the human pathogen Bordetella pertussis, the primary aetiological agent of whooping cough, was determined and analy...
Regulation of resistance to copper in Xanthomonas axonopodis pv. vesicatoria
Copper-resistant strains of Xanthomonas axonopodis pv. vesicatoria were previously shown to carry plasmid-borne copper resistance genes related to the cop and pco operons of Pseudomonas syringae an...
Sequence analysis of a 1296-nucleotide plasmid from Xylella fastidiosa
A cryptic plasmid from Xylella fastidiosa strain ATCC 35868 was cloned, sequenced, and the sequence entered into GenBank (U71220). The plasmid is 1296 nucleotides in length with 55% GC content and ...
