Effect of culture media and IAA on morphology of wild type and cgopt1 mutants. Similar results were obtained with Ori51 and Ori83 mutant strains. Only the results with Ori51 are presented. Top: Colonies of wild type and Ori51 mutant strain grown in REG liquid medium for 3 days in the absence (-) and presence (+) of 500 μM IAA. Middle: stereoscope images of individual pellets that developed in REG media with or without 500 μM IAA. Bottom: stereoscope images of individual pellets that developed in CD medium with or without 500 μM IAA. Bar = 1 mm.
