Limited regions of homology between linear and circular plasmids encoding methylenomycin biosynthesis in two independently isolated streptomycetes.
pSV1 is a plasmid in Streptomyces violaceoruber SANK95570 that carries the methylenomycin biosynthetic (mmy) gene cluster. An ordered cosmid map and an EcoRI map have been constructed for pSV1, confirming that pSV1 is a 163 kb circular plasmid. The mmy gene cluster has been found on three different replicon structures; the circular plasmid pSV1, the 356 kb linear plasmid SCP1 and, via SCP1 inte...
متن کاملCharacterization of diverse 2,4-dichlorophenoxyacetic acid-degradative plasmids isolated from soil by complementation.
The diversity of 2,4-dichlorophenoxyacetic acid (2,4-D)-degradative plasmids in the microbial community of an agricultural soil was examined by complementation. This technique involved mixing a suitable Alcaligenes eutrophus (Rifr) recipient strain with the indigenous microbial populations extracted from soil. After incubation of this mixture, Rifr recipient strains which grow with 2,4-D as the...
متن کاملGenetic analysis of homology between the virulence plasmids of Salmonella dublin and Yersinia pseudotuberculosis.
Two segments within the virulence region of Salmonella dublin plasmid pSDL2 that were homologous to regions on Yersinia pseudotuberculosis plasmid pIB1 were located with regard to the four known genes (vsdA, vsdB, vsdC, and vsdD) of pSDL2. One segment mapped upstream of vsdA within an insertion element related to IS630 of Shigella sonnei; the second was confined to a 45-bp sequence containing a...
متن کاملLack of homology between the iron transport regions of two virulence-linked bacterial plasmids.
Two plasmids involved in bacterial virulence, the Escherichia coli plasmid pColV-K30 and the Vibrio anguillarum plasmid pJM1, have been studied with respect to the iron sequestering systems mediated by these two plasmids. Bioassay results show that the two systems are not related functionally because specific iron uptake-deficient mutants in each system cannot be cross-fed by the heterologous b...
متن کاملTransduction and genetic homology between Pseudomonas species putida and aeruginosa.
Genetic crosses occur by transduction between the species Pseudomonas aeruginosa and P. putida. The frequency relative to intraspecific transfer is reduced and varies among markers, suggesting that these genomes contain discrete regions of homology and nonhomology.
