    摘要: Fluorescent Pseudomonas spp. are described which are effective for the control of diseases caused by the soil-borne fungus, Gaeumannomyces graminis (Gg), such as take-all, in small grain crops or turf grass. The subject biocontrol strains have a unique genotype as shown by a characteristic banding pattern, and exhibit root-colonizing ability which is characterized by both higher population density on roots and extended colonizing activity compared to known Gg-suppressive strains. A further property is the ability of a strain to duplicate the level of biocontrol obtained naturally in a take-all decline soil. Methods for isolation and identification of the strains and their use to control diseases caused by Gg are provided. In particular, strains of P. fluorescens NRRL B-21806 and NRRL B-21807.

    摘要: DNA sequences which function specifically in the synthesis of 2,4-diacetylphloroglucinol (Phl) are described. The sequences include phl genes which encode phl gene proteins and coding and regulatory sequences for production of Phl as well as sequences containing phl genes, which sequences have the capability of conferring or enhancing Phl biosynthetic capability in bacterial strains. The transformed strains are useful as biocontrol agents against fungal pathogens.
