Verbatim
e0“Respiratory burst oxidase homolog D (RBOHD)-dependent reactive oxygen species (ROS) in Arabidopsis are well known to suppress pathogen colonization”
e2“Conversely, elevated rhizosphere ROS levels, either triggered by pretreatment with pathogenic Dickeya solani bacteria or caused by mutations in ROS scavenging genes (e.g., in apx1 and cat2 mutants), promoted the rhizosphere recruitment of P. anguilliseptica”

Other claims from this paper (6)
- Intervention effect Pseudomonas anguilliseptica was significantly less enriched in the rhizosphere of rbohD mutants than in wild-type Arabidopsis.
- Intervention effect The promoting effect of elevated ROS on bacterial recruitment was abolished by catalase treatment.
- Intervention effect Pseudomonas anguilliseptica shows a chemotactic response to low concentrations of hydrogen peroxide (≤ 500 nM) in situ.
- Observation Pseudomonas anguilliseptica shows upregulated expression of chemotaxis- and motility-related genes under hydrogen peroxide exposure.
- Intervention effect Inoculation with Pseudomonas anguilliseptica suppressed Dickeya solani-induced disease symptoms in Arabidopsis.
- Intervention effect The protective effect of P. anguilliseptica was attenuated by catalase treatment.
