  abstract = {{B}urkholderia glumae causes bacterial leaf blight in rice, and its global spread has been exacerbated by climate change. {T}o understand the genetic diversity and virulence of {B}. glumae strains isolated from rice cultivars in {P}eru, 47 isolates were obtained from infected rice fields, all belonging to {B}. glumae, and confirmed by rec{A} and tox{B} sequences. {T}he {BOX}-{PCR} typing group has 38 genomic profiles, and these turn into seven variable number tandem repeats ({VNTR}) haplotypes. {T}here was no correlation between clustering and geographical origin. {N}ineteen strains were selected for phenotypic characterization and virulence, using both the maceration level of the onion bulb proxy and inoculation of seeds of two rice cultivars. {S}everal strains produced pigments other than toxoflavin, which correlated with onion bulb maceration. {I}n terms of virulence at the seed level, all strains produced inhibition at the root and coleoptile level, but the severity of symptoms varied significantly between strains, revealing significant differences in pathogenicity. {T}here is no correlation between maceration and virulence scores, probably reflecting different virulence mechanisms depending on the host infection stage. {T}his is the first study to evaluate the {VNTR} diversity and virulence of {P}eruvian strains of {B}. glumae in two commercial cultivars.},
