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.

In Penicilium isariiforme there occur two endogenous rhythms: the growth-“wave” rhythm and sporulation rhythm in the form of coremia-bearing zonations. The growth rhythm of wave type occurring in P. isariiforme in light and in darkness is an endogenous spontaneous rhythm, whereas the sporulation rhythm manifested by the formation of spore-bearing coremia zonations represents an analogue induced rhythm. For this rhythm to occur a light impulse is necessary. The growth-wave rhythm has a long period 120 h, the sporulation rhythm has a 30 h period. Asparagine seems to regulate the sporulation rhythm; but it does not exert any greater influence on the wave rhythm in cultures grown in light nor in darkness. An addition of asparagine shortened the period of first zonation by a few hours, and the successive sporulation periods followed within very short time. Inhibitors such as: avidin. chloramphenicol, cycloheximide and puromycine controlled the length of the period of the sporulation rhythm.
