Influence of two major virulence genes of C. michiganensis in N. benthamiana plants on the development of wilting symptoms. (A) Wilting symptoms in N. benthamiana after stem inoculation with 108 CFU/ml of C. michiganensis LMG7333T and its Tn::celA and Tn::pat-1 mutant strains. Inoculation sites are indicated by white arrows. The inoculated plants were photographed at 21 days after inoculation (dai). (B) Quantification of wilting severity in N. benthamiana plants shown in (A). An average and standard deviation (n = 4) of wilting severity are shown in the figures. The different letters on top of each bar indicate a statistically significant difference analyzed via Kruskal–Wallis test (p < 0.05). Similar results were obtained from three independent assays. (C) Confirmation of inoculated bacteria via PCR analysis with primer sets specific to the indicated genes. M, 1 kb DNA marker; N, no DNA. Scale bar = 10 cm.
