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

Abstract

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.
