Abstract
The genetic structure of a population of phyllosphere-colonising Pseudomonas isolated from sugar beet is currently being investigated by multi-locus enzyme electrophoresis (MLEE). Statistical analysis of the association between loci shows that the population, which contains both pathogenic and saprophytic species, is in linkage disequilibrium, however, this does not preclude the occurrence of recombination which can only be determined empirically by DNA sequence analysis. Following completion of the MLEE study, I propose to investigate the extent of genetic recombination by sequencing four genes (aroE, gapA, oprF and rrn) from selected isolates. Sequence data will be subjected to detailed analysis including tests for mosaic gene structure and phylogenetic congruency.
