Abstract

In contrast to most Burkholderia species, which affect humans or animals, Burkholderia glumae is a bacterial pathogen of plants that causes panicle blight disease in rice seedlings, resulting in serious damage to rice cultivation. Attempts to combat this disease would benefit from research involving a phage known to attack this type of bacterium. Some Burkholderia phages have been isolated from soil or bacterial species in the order Burkholderiales, but so far there has been no report of a complete genome nucleotide sequence of a phage of B. glumae. In this study, a novel phage, FLC5, of the phytopathogen B. glumae was isolated from leaf compost, and its complete genome nucleotide sequence was determined. The genome consists of a 32,090-bp circular DNA element and exhibits a phylogenetic relationship to members of the genus Peduovirus, with closest similarity to B. multivorans phage KS14. In addition to B. glumae, FLC5 was also able to lyse B. plantarii, a pathogen causing rice bacterial damping-off disease. This is the first report of isolation of a P2-like phage from phytopathogenic Burkholderia, determination of its complete genomic sequence, and the finding of its potential to infect two Burkholderia species: B. glumae and B. plantarii.
