FIG 1.

Infection of O. sativa L. cv Amaroo with low (10⁴ CFU/ml) and high (10⁸ CFU/ml) concentrations of B. pseudomallei TSV189 (a, root; b, leaf) and a high concentration of B. vietnamiensis 38sp (10⁸ CFU/ml) (c, root; d, leaf), as well as control uninfected groups for each infection. Area measurements include mean values with 95% confidence intervals. The low concentration of B. pseudomallei does not significantly stunt the root or leaf (root, P = 0.760; leaf, P = 0.746), while the high concentration of B. pseudomallei significantly stunts both roots and leaves (P < 0.001). The high concentration of B. vietnamiensis does not significantly stunt root or leaf growth (root, P = 0.291; leaf, P = 0.064; independent t tests, P = 0.05).
