Methods are provided including methods of promoting growth vigor in plants. In one embodiment, a method for promoting growth vigor in a plant comprises providing a plant comprising a circadian clock gene; and modifying expression of the circadian clock gene or modifying activity of a protein produced by the circadian clock gene so as to modify a flowering time of the plant; modify a starch, sugar, chlorophyll, metabolite, or nutrient content of the plant, or increase biomass or yield of the plant. In some embodiments, methods are provided including preparing a transgenic plant and using circadian clock genes as DNA and/or expression markers to select and predict the best combinations of parents to make hybrid plants with enhanced vigor. |
