Circadian Organization in Eukaryotic Microorganisms
Circadian organization is not restricted to higher plants and animals or even to multicellular organisms. Over the past 30 years, overt persisting circadian rhythms have been documented in a number of eukaryotic microorganisms (Table 2.1) for a wide spectrum of behavorial, physiological, and biochemical variables. These periodicities include mating type reversal, phototaxis, pattern formation, stimulated bioluminescence, photosynthetic capacity, cell division, chloroplast shape and ultrastructure, susceptibility to noxious agents and treatments, enzymatic activities, concentrations of metabolic intermediates, energy charge carriers, biogenic amines, and many others.
