title: Restriction analysis of an amplified polygalacturonase gene fragment differentiates strains of the phytopathogenic bacterium Pseudomonas solanacearum.
abstract: Amplification of a polygalacturonase gene fragment using the polymerase chain reaction (PCR) formed a rapid, sensitive and portable method for detecting and differentiating strains of Pseudomonas solanacearum, a taxonomically complex bacterial species. Primers 5'CAG CAG AAC CCG CGC CTG ATC CAG 3' and 5'ATC GGA CTT GAT GCG CAG GCC GTT 3' were used to amplify a 504 base pair polygalacturonase gene fragment from 57 Ps. solanacearum isolates. Digestion of these products with Hae III defined groups which reflected the known genetic divisions within the species.
