Abstract

The paper reports on studies dealing with tile effects of sulphite onthe fluidity of the tonoplast in the CAM plant Kalanchoe daigremontiana. Temperature profiles of membrane fluidity were monitored by measurements of fluorescence polarisation in fluorescence labelled tonoplastic vesicles. It was found that sulphite applied to leaf tissue prior to membrane isolation significantly decreased the fluidity of the tonoplast. Addition of sulphite to the assay medium had no effect showing that the changes of tonoplast fluidity by sulphite are not an in vitro effect. The adaptive changes in the tonoplast fluidity were accompanied by stimulation of ATPase activity and changes in the relative amounts of proteins in the ATPase subunits A, B, and C.
