Abstract
Ralstonia solanacearum is an extremely destructive and rebellious phytopathogen that can cause bacterial wilt diseases in more than 200 plant species. To explore and discover the potential targets in R. solanacearum for the purpose of developing new agrochemicals targeting this infection, here, we exploited a typical activity-based protein profiling technique for target discovery in R. solanacearum based on an activity-based probe 1 derived from bioactive oxadiazole sulfones. A total of 65 specific targets were identified with high confidence through a quantitative chemical proteomic approach. Three representative proteins (glycine cleavage system H protein, thiol peroxidase, and dihydrolipoamide S-succinyltransferase) were validated as the targets by using the immunoblotting analysis with their respective antibodies. Additionally, the in vitro interaction between the recombinant thiol peroxidase and probe 1 further confirmed that this protein was a target of oxadiazole sulfones. We anticipated that these discovered protein targets in R. solanacearum can stimulate the discovery and development of novel agrochemicals targeting bacterial infections caused by R. solanacearum.
