Utilization of plasmid pULB113 (RP4::mini-Mu) to construct a linkage map of Erwinia carotovora subsp. chrysanthemi.

RESUMO

We report experimental evidence that pULB113, an RP4::mini-Mu plasmid, mediates chromosome transfer in a strain of Erwinia carotovora subsp. chrysanthemi which does not accept the F episome. This allowed us to construct a genetic map of that strain by measuring the frequencies of cotransfer of different markers (thy, leu, pro, [his, trp], thyA, rpsL, ile).
