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 morphological alterations were not detected. In addition, the protein electrophoretic profile of cultures submitted to cold-shock was different from that of cultures kept at 30 degrees C. After 1 and 2 hours at 4 degrees C at least 5 bands were more intense than at 30 degrees C. The results suggest that cold-shock temporarily increases the synthesis of some proteins probably involved in the acclimatization process at 4 degrees C, and that the effects on morphology are probably due to damage to calcium influx.
