RESUMO

A physical chromosomal map of Acholeplasma oculi ISM1499 was constructed by using field inversion gel electrophoresis. To assist in the ordering of the chromosomal fragments, a modified transposon, Tn4001.1064, was constructed. It was also used to rescue mycoplasmal chromosomal sequences adjacent to transposon insertion sites in a one-step cloning procedure. The total size of the A. oculi ISM1499 genome was estimated to be 1,633 kb. The restriction enzyme sites for ApaI, BssHII, EagI, and SmaI were positioned on the map along with several transposon insertion sites.
