Comments P.356 right column bottom paragraph: "[Investigators] also suggest that the flared end is a growing MT [microtubule] end morphology due to the following reasons: (1) [Their] cells are ~7µm long. Thus, it should take the MTs ~1 min to grow half the cell’s length but only about 30 s to depolymerize back to the cell’s midplane (growth speed ~3µm/min, shrinkage speed 8.5µm/min, from primary source)."
