Research
on circadian clocks has centred on genes encoding clock function proteins. The
first hint that noncoding RNAs might be involved in natural clocks came from the
silkmoth, where an antisense period transcript was discovered. The exact role
of the RNA has remained elusive. Now antisense transcripts of a central clock
component in the fungus Neurospora have been identified. The antisense
version of frq messenger RNA plays a central role in the perception of
time by sensing frq transcripts in the dark, and the antisense frq
is induced in the light.
