Summary

With an improved method to visualize the actin filament system it is possible to detect a small, peculiar accumulation of actin filaments under the prospective area of side branch formation inFunaria protonema cells. It consists of a ring-like configuration of actin filaments from which filaments radiate, preferentially along the plasma membrane. During the transition to tip growth the arrangement becomes loosened and eventually disappears whereas the filaments are concentrated in inner regions of the cytoplasm with a maximum in the apical dome.
