Wechsler and GrossSex:
F- Chromosomal Markers: thr-1
, met-89Strain Comments:
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- thyA6-- : Even with Luria or other complete media, supplement with thymine.
- thyA6-- 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.
