Development of BR-F colonies. Cells of the BR-F strain were plated on Petri dishes with GMA agar and grown at 28°C. Images of developing colonies were captured in incident light of light-emitting diode illumination using a DS-5M camera with a Navitar 12× objective operated by a time-lapse image-recording NIS-Elements system. Frames were taken every 45 min starting at 11 h for 123 h. This video is related to Fig. 1 A.
