title: Catalase activity during C3-CAM transition in Mesembryanthemum crystallinum L. leaves.
abstract: Treatment with 0.4 mol dm(-3) NaCl caused a C3-CAM shift in Mesembryanthemum crystallinum L. leaves. In parallel to the CAM induction the activity of CAT was significantly decreased. In C3 and in CAM plants CAT activity showed daily fluctuations, with the maximum at the end of the light period. The oscillations of CAT were more pronounced in CAM than in C3 plants. In M. crystallinum CAT activity seems to respond more to CAM induction than to salinity.
