Fruit flies and plants have independently come up with similar ways to mark time, a new study suggests.
Both modify the products of certain genes based on daily rhythms set by the organisms’ circadian clocks, the study shows. The finding, published online October 20 in Nature, may help scientists better understand how plants and animals respond to light-dark cycles.
Most research on circadian clocks has focused on the process by which the biological timekeepers turn genes on and off. But ...
