DF575      Source of Strain:
F- Chromosomal Markers: glnV44
, thiE1Strain Comments:
- 1.This strain can be grown in a minimal medium containing malate (25mM), glycerol (12.5 mM) and casamino acids (0.1%).It should not be grown in the presence of glucose, which selects for revertants.
- 2.Reference: Hillman and Fraenkel 1975 J.Bacteriol.122:1175
- Donor markers transferred early in the cross, but not near the selected region and not been tested for: fhuA22, garB10, creC570, mcrB1, rrnB-2, spoT1, pit-10. relA1 is a donor marker near the selected argA+ and very likely to be
- The markers shown with ? marks are carried by the recipient parent in regions not selected for, but introduced early by the Hfr. λ- and glnV44 are recipient markers in a region transferred very late, so are likely to be present.
- eno-2-- : Mutations in the eno, gap, and pgk genes all revert and must be monitored closely; they should not be grown in media containing glucose.
