Cell death responses are unaltered in A. thaliana SNUPO mutants. Differential interference contrast microscopy of A. thaliana wild-type (Col-0) and CSG mutant leaves stained with trypan-blue lactophenol 4 dpi with Hpa isolate Noco2.
First column, non-infected without cell death; second column, non-infected with random cell death; third column, infected with cell death in, or adjacent to, haustoria-containing cells; fourth column, infected without cell death. Bars, 25 μm. Boxplots represent the number of random (upper graph) or Hpa-associated (lower graph) cell death spots per leaf on A. thaliana wild-type (Col-0) or the indicated mutants 5 dpi with Hpa isolate Noco2. On each leaf four to ten spots have been analysed and a total of five leaves per genotype were investigated. Circles, data points outside 1.5 IQR of the upper/lower quartile; bold black line, median; box, IQR; whiskers, lowest/highest data point within 1.5 IQR of the lower/upper quartile. Stars indicate significant differences to Col-0 (Wilcoxon-Mann-Whitney test with Bonferroni-Holm correction; *, p < 0.05; **, p < 0.01; ***, p < 0.001).
