Effects of the <i>cabA</i> mutation on colony morphology.

<p>(A) The strains were spotted onto VFMG-CF agar plates supplemented with or without 0.02% of arabinose and 10 mM of CaCl₂. Then, the plates were incubated at 30°C for 3 d. Ampicillin and kanamycin (200 μg/ml for each) were used to maintain plasmids in the strains. Each colony representing the mean rugosity of colony morphology from at least three independent experiments was visualized using a stereomicroscope (Stemi DV4, Zeiss) at an 8× magnification. Bars, 1 mm; JN111 (pJK1113), parent strain; <i>cabA</i> (pJK1113), <i>cabA</i> mutant; <i>cabA</i> (pYM1109), complemented strain.
