Uses One Type VI Secretion System (T6SS-1) as a Powerful Weapon against Notorious Plant Pathogens.

Paraburkholderia sabiae LMG24235 is a nitrogen-fixing betaproteobacterium originally isolated from a root nodule of Mimosa caesalpiniifolia in Brazil. We show here that this strain effectively kills strains from several bacterial families (, , ) which include important plant pathogens in a contact-dependent manner. assembly of the first complete genome of using long sequencing reads and subsequent annotation revealed two gene clusters predicted to encode type VI secretion systems (T6SS), which we named T6SS-1 and T6SS-3 according to previous classification methods (G.
