Circadian Influence In Plants More Widespread Than Previously Thought, ScienceDaily Bookmark and Share

Excerpts: While picking apart the genetic makeup of the plant Arabidopsis, two Dartmouth researchers made a startling discovery. They found that approximately 36 percent of its genome is potentially regulated by the circadian clock, which is three and a half times more than had previously been estimated. Their research on circadian-controlled genes contributes to efforts to help improve plant productivity and can possibly lead to growing crops that are more resistant to stressful soil or climate conditions. In this study, the researchers randomly inserted a gene that encodes an easily measurable element, (...) into the genome to see what genes would be involved in mRNA synthesis.
