F- Chromosomal Markers: thr-33
, argH212Strain Comments:
- (Reference describes closely related strains.)
- thyA707-- Strains with this marker must have their medium supplemented with thymine (25ug/ml). This is true even for rich medium such as LB. Otherwise thymine starvation can lead to thymineless death.
- IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
- Am = amber(UAG) mutation
