title: Construction of tn3-containing plasmids from plant-pathogenic pseudomonads and an examination of their biological properties.
abstract: Indigenous plasmids isolated from Pseudomonas tabaci ATCC 11528(pJP1), Pseudomonas angulata 45(pJP30), and P. tabaci BR2(pBPW1) (M. Obukowicz and P. D. Shaw, J. Bacteriol. 155:438-442, 1983) were labeled with Tn3, and the strains were subsequently cured of their respective plasmids. Plasmid-containing and cured isolates caused plant symptoms that were nearly indistinguishable, and the same amount of tabtoxin was produced by P. tabaci strains ATCC 11528 and BR2.
