Combined DAB and Trypan blue staining to determine ROS accumulation on leaves of inoculated WT and mutant plants at 10 dpi. Although susceptible WT-ADR27 had highest P. xanthi germination rate, ROS accumulation (black arrow) was found more frequently on the leaves of these plant as compared 4-11 and 4-14. ROS accumulation was also found in 4-11 and 4-14 which are CsaMLO8/11del and CsaMLO1 A137N/8/11del mutants. However, ROS were accumulated in the P. xanthii mycelial growth site was detected in 4-11 and 4-14. Also, non-germinated spores (red arrow) were detected on mutant leaves on the contrary to WT.
