Complete genome sequence of Xanthomonas phage M29, a new member of Foxunavirus isolated in the Czech Republic.

The newly discovered Xanthomonas phage M29 (Xp M29) is the first lytic phage infecting Xanthomonas campestris pv. campestris (Xcc) that was isolated from cabbage leaves in the Czech Republic. The phage consists of icosahedral head approximately 60 nm in diameter and a probably contractile tail of 170 nm. The complete genome size was 42 891 bp, with a G + C content of 59.6%, and 69 ORFs were predicted on both strands. Pairwise nucleotide comparison showed the highest similarity with the recently described Xanthomonas phage FoX3 (91.2%). Bacteriophage Xp M29 has a narrow host range infecting 5 out of 21 isolates of Xcc. Xp M29 is a novel species in a newly formed genus Foxunavirus assigned directly to the class Caudoviricetes.
