Abstract/Contents: | Profiles Lysobacter enzymogenes, "a common, soil-inhabiting bacterium which produces copious amounts of antibiotics and lytic enzymes and has been shown to suppress summer patch disease of cool season turfgrasses caused by root-infecting, fungal ascomycete, Magnaporthe poae." Explains that "L. enzymogenes is not known to attack vascular plants or animals, and...infectivity studies confirm that plants react to it as they do with other non-pathogens." Mentions "limited host range studies on different fungi in culture" to determine "whether there are measurable differences in virulence to different fungal species or strains." Reports that "the bacterium was pathogenic to Magnaporthe oryzae, the gray leaf spot pathogen; Colletotrichum cereale, the anthracnose pathogen; and Rhizoctonia solani, the brown patch pathogen. Levels of virulence appeared to differ among fungal host strains, as determined by size of clearing zone, resulting from innoculations of bacterial suspensions directly onto fungal colonies." States that "in each of the hosts in which the bacterial/host interaction has been examined carefully, the bacterium has been shown to internalize within host cells, a very unusual property for pathogenic bacteria and one that has implications for gene expression of both the bacterium and host during colonization." Mentions the identification of the bacterial type III secretion system and a clp regulator gene "that globally controls expression of a variety of traits associated with antifungal activity." |
