  1. a n = 60 cells each.
  2. b n = 20–27 cells each.
  3. c Estimated outer surface area of a tube, calculated at https://onlinevonversion.com/object_surfacearea_tube.htm.
  4. d Given as number of mean ± STDEV actin patch number per 1 µm2 (n = 13–16).
  5. e Average of the number in the apical 5 µm (0.87 ± 0.20, n = 13), the middle region (0.54 ± 0.18, n = 15) and 5–10 µm before the septum (0.42 ± 0.10, n = 13).
  6. f Activity in the entire cell; for the tip cell, the average of 3 regions was used.
  7. g Relative endocytic activity compared to the that in hyphal apex.
