Abstract:
Expression of the three SBE genes, encoding starch branching enzymes, in the sorghum endosperm exhibited a diurnal rhythm during a 24-h cycle. Remarkably, the oscillation in SBE expression was maintained in cultured spikes after a 48-h dark treatment, also when fed a continuous solution of sucrose or abscisic acid. Our findings suggest that the rhythmicity in SBE expression in the endosperm is independent of cues from the photosynthetic source and that the oscillator resides within the endosperm itself.
