Summary of selected cell wall defective mutants.
| Cell line | Cell morphology | Cell wall phenotype | cwd classificationa | NP-40 sensitivity |
|---|---|---|---|---|
| cw15 (CC-3491) | round cells | some material in medium | C | high |
| cwd1 | round cells | no wall material present | C | high |
| cwd2 | teardrop shaped; cell aggregates | unevenly distributed | B | medium |
| cwd3 | oval cells | ruffled-looking edges | B | high |
| cwd4 | gap between membrane and cell wall | normal looking | B | high |
a(A) cells producing normal-looking walls attached to the plasma membrane, (B) cells producing walls but not connected to the plasma membrane, and (C) cells producing minute amounts of wall material, according to Davies and Plaskitt25.
