Dual Role of TOC1 in the Control of Circadian and Photomorphogenic Responses in Arabidopsis.

Examines the role of the Timing of Cab Expression1 (TOC1) gene in the Arabidopsis circadian system, using a series of transgenic plants expressing a gradation in TOC1 levels. Comparison between the effects of TOC1 gene dosage and TOC1 overexpression on the plant circadian clock; Role of TOC1 in the red light-dependent control of circadian gene expression; Analysis of the circadian function in the presence of constitute levels of TOC1 using transgenic plants; Significance of TOC1 gene as a component of the plant clock.
