Increased oxygen consumption causes hypoxia in crown galls. (A) Oxygen consumption rate of crown galls and stem tissue. O2 consumption rate over time was calculated per gram fresh weight. (B) Oxygen concentration (% of air saturation) in crown galls, measured at 14 and 28 dpi using an oxygen microsensor. (C) Photographs of tumor formation on Arabidopsis stems after 14 and 28 days of inoculation with Agrobacterium tumefaciens. Arrows indicate the position of the microsensor. Scale bars, 1 mm. Data are presented as means ± SE of at least 4 independent measurements. Stars indicate a statistically significant difference [<0.05, ∗∗<0.01, one-way analysis of variance (ANOVA) followed by Holm-Sidak post hoc-test].
