Whole Genome Sequence of Xylella fastidiosa ATCC 35879(T) and Detection of Genome Rearrangements Within Subsp. fastidiosa

Text - scientific article/review article


Xylella fastidiosa is a Gram-negative and nutritionally fastidious bacterial pathogen causing Pierce's disease (PD) of grapevine and other plant diseases. X. fastidiosa strain ATCC 35879(T) which originated from Florida is the designated type strain for the species and for subsp. fastidiosa. In bacterial taxonomy, type strains preserve the characters of the original descriptions. Whole genome sequence of a type strain not only provides a standard reference for bacterial taxonomy, but also facilitates research in other fields such as population diversity and genome evolution. In this study, the whole genome sequence of strain ATCC 35879(T) was determined using PacBio RSII format. The ATCC 35879(T) genome has a circular chromosome of 2,565,504 bp with 2,904 predicted protein coding genes and 55 RNA genes, and a circular plasmid of 41,753 bp. The chromosomal sequence of strain ATCC 35879(T) was compared to that of X. fastidosa subsp. fastidiosa strain M23 from California which causes both PD and almond leaf scorch disease. Genome rearrangements involving a 1,200 K bp region were detected. Genome annotations showed clusters of phage-related genes around the rearrangement junctions, suggesting the likely involvement of phage activities. This is the first report on genome structure variations within strains of X. fastidiosa subsp. fastidiosa.
