Biologists identify genes controlling rhythmic plant growth
Date:9/15/2008

l fellow at Salk who is now an assistant professor of genomics and bioinformatics at the Waksman Institute and Rutgers University. Other coauthors included UCSD postdoctoral fellows Ghislain Breton and Samuel Hazen, and assistant professor of genome biology, Todd Mockler, and graduate student Henry Priest of Oregon State.

How plants grow to maximize their survival in different environments has long fascinated biologists. In 1880, Charles Darwin published The Power of Movement in Plants, one of his lesser-known books in which he describes his studies on the manner by which different types of plants grow and move in response to various stimuli.

While most people might assume that plants grow at a slow and steady rate throughout the day and night, Darwin and others found that they grow in regular nightly spurts, with plant stems elongating fastest in the hours just before dawn.

"Plants actually grow rhythmically," said Kay. "Some plants, like sorghum, have the ability to elongate a centimeter or more each night."

Why plants have evolved mechanisms to grow rhythmically at night or in the hours just before dawn is a mystery. But a similar interplay of light sensing, plant hormones and circadian rhythms that leads to a pronounced rhythmic growth by plants during certain seasons and when shaded by other plants has a clear survival value.

"Any plant that is growing is in a situation in which it has to compete with the plants growing around it, so it has to develop ways in which it can measure its environment to enable it to compete," said Kay. "Plant cells have phytochromes, which are essentially shade detectors that measure the ratio of different colors of light that can tell a plant whether it's a cloudy day or whether it's being shaded by an
