A strain of the phytopathogenic bacterium Pseudomonas syringae
pv. phaseolicola, a pathogen of common bean Phaseolus vulgaris,
harbors a 150 kilobase pair (kb) plasmid pMC7105. In one strain,
LR719, pMC7105 is stably integrated in the bacterial chromosome.
Imprecise excision of the pMC7105 replicon has been shown to result
in the...
Conditions were established for inducing pear blossom blast
caused by Pseudomonas syringae (Ps) on both attached and detached
shoots. The incidence of disease was proportional to the log of Ps
population under optimal temperature, moisture and bloom developmental
stage. Highest incidence of infection followed occurrence of a major
exotherm in...
