The group of strains constituting the Ralstonia solanacearum species complex (RSSC) is a
prominent model for the study of plant-pathogenic bacteria because of its impact on …

Plants defend themselves from most microbial attacks via mechanisms including cell wall
fortification, production of antimicrobial compounds, and generation of reactive oxygen …

Successful infection by pathogenic microbes requires effective acquisition of nutrients from
their hosts. Root and stem rot caused by Phytophthora sojae is one of the most important …

The type III secretion system with its delivered type III effectors (T3Es) is one of the main
virulence determinants of Ralstonia solanacearum, a worldwide devastating plant …

Polyamine (PA) catabolic processes are performed by copper-containing amine oxidases
(CuAOs) and flavin-containing PA oxidases (PAOs). So far, several CuAOs and PAOs have …

The plant wilt pathogen Ralstonia solanacearum thrives in the water-transporting xylem
vessels of its host plants. Xylem is a relatively nutrient-poor, high-flow environment but R …

Most of the phylogenetic diversity of life is found in bacteria and archaea, and is reflected in
the diverse metabolism and functions of bacterial and archaeal polyamines. The polyamine …

Plant-pathogenic Ralstonia spp. colonize plant xylem and cause wilt diseases on a broad
range of host plants. To identify genes that promote growth of diverse Ralstonia strains in …

Polyamines (PAs) are ubiquitous amine molecules found in all living organisms. In plants,
beside their role in signaling and protection against abiotic stresses, there is increasing …

Ralstonia solanacearum (biovar2, race3) is the causal agent of bacterial wilt and this
quarantine phytopathogen is responsible for massive losses in several commercially …
