Single particle dynamic colocalization analysis of GFP-labeled mitochondria with ROS-accumulating compartments after staining with CellROX Deep Red in root hairs. A to C) Three different time points from time-lapsed video-recordings of growing root hairs containing GFP-tagged mitochondria (in green) and ROS-accumulating compartments (in magenta) after CellROX Deep Red staining. D) Video-sequence captured from dashed box in (A) showing mitochondria (green arrows) and ROS-accumulating compartments (magenta arrows) colocalized (double arrows in merge), while small individual mitochondria in the clear zone are still free of ROS (green arrows only in merge). E) Video-sequence captured from dashed box in (B) showing small mitochondrion negative for ROS staining (green arrow) independent from larger mitochondria containing ROS (double arrows in merge). F) Video-sequence captured from dashed box in (C) showing large round and immobile mitochondria containing ROS (double arrows in merge) and small mobile individual mitochondria free of ROS (green arrows only in merge). Time sequences (in seconds) are shown in mito-GFP channels (D to F). Scale bar = 5 µm (A to C), 1 µm (D to F).
