abstract：:The effects of cold-shock on Neurospora crassa was here investigated. In cold-shock treated hyphae (6 h at 4 degrees C) the branching pattern was changed and dichotomy as well as a fan-like-pattern structure were temporarily detected at the tips. When exogenous Ca(2+) (500 mM) was added to the hyphae, these morphologi...
