CGSC Strain#: 4360
Strain Designation: KMBL1789      Source of Strain: A. Rorsch
Sex: F- Chromosomal Markers: λ^-, bioA2, pheA97, argA103, thyA305, endA101, polA107, deoB301
Strain Comments:

• thyA305 mistakenly designated thyA301 in the paper below. bioA2 designated bio-87 in paper below.
• thyA305-- 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.
• = good miniprep dsDNA quality
