FIG. 4.
Spreading phenotype of M. smegmatis colony morphology variants. (A) Colony morphology of mc2155, Sm-1, and Rg-1 on 7H10 agar plates. (B and C) Spreading phenotype of the morphology variants in 0.3% agarose plates containing M63 salts (B) or M63 with 2% glucose and 0.5% Casamino Acids (C). For both plates: mc2155, top left; Sm-1, top right; Rg-1, bottom.
