✦ Synopsis

Lhc, genes encoding proteins of the light-harvesting complex of PSI/PSII (ref. 16; old nomenclature is given in { }); rbcS and rbcL, genes encoding the small and large subunit of Rubisco, respectively; clip, gene encoding early light-induced protein; psbA, quinone-binding protein; psaA, gene encoding P700 protein of PSI; chl, chlorophyll This paper summarizes (1) the genes which show diurnal or circadian oscillations at the transcript level in plants, (2) the features of these rhythms, and (3) experimental approaches that can elucidate possible control steps or the mechanism(s) involved. The latter may provide indications that ultimately may lead to the understanding of the 'hands of the clock' or the 'oscillator(s)'.

Steady-state mRNA oscillations

Accurate development and growth of all living organisms require a precise temporal and spatial
