CGSC Strain#: 6827
Strain Designation: χ2904      Source of Strain: R. Curtiss
Other Designations: chi2904
Sex: F- Chromosomal Markers: λ^-, thyA748::Tn10, rph-1
Strain Comments:

• thyA748::Tn10-- 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.
• rph-1-- is a 1 bp deletion that results in frameshift over last 15 codons and has polar effect on pyrE leading to suboptimal pyrimidine levels on minimal medium.(Jensen 1993 JBact.175:3401)
• = tetracycline resistant
