摘要

High-resolution video microscopy, image analysis, and computer simulation were used to study the role of the Spitzenkorper (Spk) in apical branching of ramosa-1, a temperature-sensitive mutant of Aspergillus niger. A shift to the restrictive temperature led to a cytoplasmic contraction that destabilized the Spk, causing its disappearance. After a short transition period, new Spk appeared where the two incipient apical branches emerged. Changes in cell shape, growth rate, and Spk position were recorded and transferred to the FUNGUS SIMULATOR program to test the hypothesis that the Spk functions as a vesicle supply center (VSC).
