Co-localization of GFP-CESA3 and mCherry-TUA6 in exocarp cells of C. hirsuta fruit at 0, 48, and 96 h, starting with 7-mm-long fruit at 0 h. Average projections of confocal time-lapse movies (Videos S1,S2, and S3) showing GFP-CESA3 (green), mCherry-TUA6 (magenta), and merge of both channels. Orientation and magnitude of CESA3 trajectories and CMT arrays calculated with FibrilTool and shown as direction and length of blue lines.
