CGSC Strain#: 7361
Strain Designation: CAG12078      Source of Strain: C.A. Gross
Sex: F- Chromosomal Markers: λ^-, zce-726::Tn10, rph-1
Strain Comments:

• zce-726::Tn10-- cotransduces 9% with pyrC and 85% with ptsG (and 5% with csgD). PCR analysis (Nichols et al.1998) places this insertion in orf yceG, at nucleotide 1,154,216 (24.88 min.).
• 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
