Representative of race 6. Xanthomonas oryzae pv. oryzae PXO99A

Xanthomonas oryzae pv. oryzae PXO99A. This strain is a representative strain of race 6 isolated in the Philippines. This plant pathogen affects rice plants by causing leaf blight, a major problem in Asian countries where rice production occurs on an industrial scale. This organism enters the xylem and spreads throughout the vascular tissue of the plant, which results in wilting of the plant, or to leaf blight if the infection occurs later in development. Xanthomonas oryzae pv. oryzae PXO99A will be used for comparative analysis with other plant pathogenic Xanthomonas species.
