Abstract
Bacteria inhibitory to the growth of wheat isolated from wheat roots were identified using cell wall fatty acids and cultural characteristics. Using fatty acid profiles, the largest single group was identified as Pseudomonas corrugata. Comparison of this group with reference isolates by cultural characteristics showed that although they shared some of the characteristics of P. corrugata they were not identical. When these bacteria were inoculated into tomato stems, symptoms characteristic of those caused by P. corrugata developed although no deaths occurred. It is suggested that these bacteria are part of a poorly characterised group of soil bacteria that show varying pathogenicity to plants.
