λRStrain Comments: - DV1 requires β-alanine, even on rich medium. It cannot grow on pantothenate.
- zad-220::Tn10-- cotransduces 96-98% with panD. The insertion is in orf yadC (at nucleotide 150,100, minute 3.235).
- panF11-- was called panF1 in the paper cited below.
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
- λR-- Lambda resistant, locus unknown.
- zad-220::Tn10 was formerly called yadC
- = tetracycline resistant
- NalR = Nalidix.acidResist.
