Rough and fine linkage mapping of the Rhizobium meliloti chromosome

J Casadesús et al. Mol Gen Genet. .

Abstract

A circular linkage map of the Rhizobium meliloti chromosome, obtained from R68.45-mediated crosses, has been revised by cotransductional analysis, after general transduction by DF2 phage. Three short chromosomal regions have been mapped by cotransduction. Comparison between conjugal and cotransductional data suggests that R68.45-mediated linkage measures are indeed rough. Cotransduction seems to be a useful tool for improving the linkage map of R. meliloti.
