The Bacterial Wilt Reservoir Host Shows Resistance to Infection.

causes bacterial wilt, a devastating plant disease, responsible for serious losses on many crop plants. phylotype II-B1 strains have caused important outbreaks in temperate regions, where the pathogen has been identified inside asymptomatic bittersweet () plants near rivers and in potato fields. is a perennial species described as a reservoir host where can overwinter, but their interaction remains uncharacterised.

Identification of Type III Secretion Inhibitors for Plant Disease Management.

Bacterial plant pathogens are among the most devastating threats to agriculture. To date, there are no effective means to control bacterial plant diseases due to the restrictions in the use of antibiotics in agriculture. A novel strategy under study is the use of chemical compounds that inhibit the expression of key bacterial virulence determinants.

Twitching and Swimming Motility Play a Role in Ralstonia solanacearum Pathogenicity.

is a bacterial plant pathogen causing important economic losses worldwide. In addition to the polar flagella responsible for swimming motility, this pathogen produces type IV pili (TFP) that govern twitching motility, a flagellum-independent movement on solid surfaces. The implication of chemotaxis in plant colonization, through the control flagellar rotation by the proteins CheW and CheA, has been previously reported in In this work, we have identified in this bacterium homologues of the and genes, suggested to play roles in TFP-associated motility analogous to those played by the and genes, respectively.
