Abstract
The genome of Xanthomonas campestris pv. vesicatoria encodes a constitutively expressed
small RNA, which we designate PtaRNA1, “Plasmid transferred anti-sense RNA”. It exhibits all
hallmarks of a novel RNA antitoxin that proliferates by frequent horizontal transfer. It shows an
erratic phylogenetic distribution with occurrences on chromosomes in a few individual strains
distributed across both beta- and gamma-proteobacteria. Moreover, a homologous gene
located on plasmid pMATVIM-7 of Pseudomonas aeruginosa is found. All ptaRNA1 homologs
are located anti-sense to a putative toxin, which in turn is never encountered without the small
RNA. The secondary structure of PtaRNA1, furthermore, is very similar to that of the FinP
anti-sense RNA found on F-like plasmids in Escherichia coli.
