Figure 4.

μ2-YFP and mCherry-CESA6 have overlapping distributions in planta. Confocal optical sections show epidermal cells of a 3-d-old etiolated hypocotyl coexpressing mCherry-CESA6 and μ2-YFP. mCherry-CESA6 and μ2-YFP puncta are visible at the plasma membrane (left) and in intracellular compartments (right). Arrows indicate examples of colocalized particles at the plasma membrane. Intracellular images were obtained at a focal plane that is 0.75 to 1.25 μm below the plasma membrane. Bars = 10 μm.
