GIGANTEA acts in blue light signaling and has biochemically separable roles in circadian clock and flowering time regulation.

Plant physiology - 1 Jan 2007

Martin-Tryon Ellen L, Kreps Joel A, Harmer Stacey L

Abstract excerpt

Circadian clocks are widespread in nature. In higher plants, they confer a selective advantage, providing information regarding not only time of day but also time of year. Forward genetic screens in Arabidopsis (Arabidopsis thaliana) have led to the identification of many clock components, but the functions of most of these genes remain obscure. To identify both new constituents of the circadian clock and new...
