This proposal will unravel the regulatory mechanisms controlling carotenoid composition as well as plant growth.
Carotenoids are colourful pigments found in plants and are essential for human health. In plants, carotenoids are necessary for photosynthesis and the production of signalling molecules (hormones). We will elucidate mechanisms regulating carotenoid composition and the production of carotenoid-derived signaling molecules. The nature of the carotenoid signals and epigenetic processes are being elucidated using Arabidopsis and tomato as model plant systems.
