In a study of the molecular underpinnings of plants’ pest resistance, biologists have shown that plants use circadian rhythms to both anticipate raids by hungry insects and to time the production of defensive hormones that protect against insect attack. The researchers demonstrated that when the plants’ timing was shifted, the plants were defenseless against daytime-feeding caterpillars.

Yale University researchers have identified a key genetic gear that keeps the circadian clock of plants ticking, a finding that could have broad Circadian Responses Keeping time with biological clocks. Plants, like other living things, have biological clocks that allow them to respond to changes in time. Among the more obvious clock responses are "sleep movements" such as Sunflower have also given scientists a peek in the world of how improve their growth and ensure propagation.
