Necrotrophic growth of virulent Pst DC3000 is inhibited in AteIF5A-2-suppressed lines. Pathogen growth was scored as CFU/leaf disc for wild-type plants, three AteIF5A-2 antisense lines (AS1, AS2, and AS3), and two AteIF5A-2-overexpressing lines (OE9A and OE3F) following infection with virulent Pst DC3000. Time after inoculation with the pathogen is indicated. CFU/leaf disc at 24 h reflects apoplastic growth. The increase in CFU/leaf disc between 24 and 72 h reflects necrotrophic growth. The insert illustrates the data for 72 h postinfection plotted on a linear scale. **, Significant difference at P < 0.01 compared to the mean for wild-type plants. *, Significant difference at P < 0.05 compared to the mean for wild-type plants.
