Five new hosts of Pseudomonas andropogonis occurring in eastern Australia: host range and characterization of isolates

Pseudomonas andropogonis was recorded for the first time as the cause of lesions on blueberry (Vaccinium sp.). carob (Ceratonia siliqua L.), Gypsophila paniculata L. G. elegans Bieb. and statice (Limonium sinuatum (L.) Mill). Cross-inoculation studies with 13 isolates from 10 host plants showed that sorghum, sweet corn, vetch, carnation and Gypsophila elegans were hosts in common, whereas clovers (Trifolium repens and T. pratense) were infected only by isolates from clover, Gypsophila paniculata and vetch. Seventeen isolates subjected to bacteriological characterization tests formed a uniform phenotype. A single isolate from sorghum produced an antimetabolite inhibitor of Escherichia coli B which was reversed by L-glutamine. but not by other amino acids.
