The different acid invertase activity (total, soluble, wall-bound and extracellular) in calli induced on explants (cotyledon, petiole, hypocotyl and leaf) originated from Medicago strasseri seedlings were evaluated. In cultures subjected to 16 h photoperiod, the highest total, soluble and extracellular activities were found in calli from leaves cultured in medium 12 (MS with 0.01 mg·dm⁻³ (0.045 µM) of TDZ), elevated amounts of total and wall-bound invertase being found in calli induced on petioles in 12G medium (MS with 0.01 mg·dm⁻³ (0.045 µM) TDZ and 3.104 mg·dm⁻³ glycerol). In cultures maintained in darkness, the activity detected was lower than that observed in cultures under light conditions. The highest amounts of enzyme was bound in calli cultured on medium 12 (total and extracellular invertase) -leaves- and medium 12D (MS with 0.001 mg·dm⁻³ (0.0045 µM) TDZ) (soluble invertase) -using hypocotyls. In general, the different forms of invertase activity studied seem to appear in greatest amounts in calli induced under light conditions using leaves as explant and TDZ as growth regulator.

The amounts of mRNA of subunit-c (proteolipid) of the V-ATPase of mature leaves of Mesembryanthemum crystallinum L. in the state of C3-photosynthesis were analyzed for a time-series of 96 h under constant conditions in continuous light. Fourier-transform analysis of the data showed endogenous oscillations of the mRNA with period lenghts of 48, 24 and 12 h, i.e. harmonic frequency resonances.
