Sustainable natural bioresources in crop protection: antimicrobial hydroxycoumarins induce membrane depolarization‐associated changes in the transcriptome of Ralstonia solanacearum

Our transcriptomic analyses show that specific hydroxycoumarins suppressed gene expression involved in fatty acid synthesis, RNA modification, ribosomal submits, oxidative phosphorylation and electrontransport. These findings provide evidence that hydroxycoumarins inhibit R. solanacearum growth through multi-target effect. Hydroxycoumarins could serve as sustainable natural bioresources against plant bacterial wilt through membrane destruction targeting the lipopolysaccharides biosynthesis pathway.
