Nomenclature
The members of the genus Burkholderia were formally classified as Pseudomonas, but Burkholderia was one of the seven genera that arose when Pseudomonas was divided based on rRNA differences. Burkholderia gladioli is closely related to, and often mistaken for, a member of the Burkholderia cepacia complex. This includes ten closely related species, which are all plant pathogens.
Burkholderia gladioli is divided into three pathovars: gladioli, allicola, and agaricicola. B. gladioli pv. gladioli causes gladiolus rot, allicola causes onion bulb rot, and agaricicola causes soft rot in mushrooms
