Cellulose-deficient mutants exhibit enhanced resistance to the bacterial pathogen Ralstonia solanacearum. A, B Disease scoring of cellulose-deficient mutants (A) and the ET signaling mutant ein2-5 in WT (Col-0) and ctl1-2 genetic backgrounds (B) at various days post-treatment (dpt) with the vascular bacteria R. solanacearum GMI1000. Qualitative data represented as line plots represents the average of at least 3 independent experiments, each one including ≥ 24 plants per genotype. Based on plant symptoms on each day, an average disease score was calculated per time point represented in line graphs. The disease scoring index measured symptoms on a scale of 1 to 4 (0 = no wilting, 1 = 25% wilted leaves, 2 = 50%, 3 = 75%, and 4 = death) as described in the methods. Statistical significance based on absolute number of plants assigned to either the least (≤ 1) or most (> 3 ≤ 4) diseased category calculated via Fisher’s exact contingency test indicated in Additional file 12: Table S6 A-G
