Ocean Bacteria’s Genes Are in Perfect Harmony

Ocean Bacteria's Genes Are in Perfect HarmonyOcean bacteria may be the ultimate synchronized swimmers. The tiny sea dwellers coordinate the genes they turn on and off in sync with the day-night cycle — and each other, a new study shows. The pattern, described today (July 10) in the journal Science, is driven in large part by phototrophs, or organisms such as cyanobacteria that convert solar energy into food. "The solar energy that's absorbed by the phototrophs is very quickly and immediately and in great synchrony passed onto the rest of the organisms that live in the oceans," said David Karl, an oceanographer at the University of Hawaii who was part of the expedition that collected data, but did not co-author the new study.
