Time course of EZ buildup inside a single pumpkin xylem vessel at (a) 1 min, (b) 3.5 min, (c) 6 min, and (d) 11 min. By using a dissection needle and a tweezer, we could isolate and observe single pumpkin vessels with a length of 200 μm and an inner diameter of ~ 230 μm from a transverse perspective. The isolated vessel was carefully placed vertically into a suspension of carboxylate microspheres.
