Improvement of Biomass and Grain Yield in Crop Plants

A rice transcription factor gene (HYR) increases plant biomass and photosynthetic rates leading to an increase in grain yield. In addition, transformed rice plants display improved water use efficiency and exhibit significantly higher biomass accumulation as well as grain yield over wild type control plants under drought conditions.Transforming and over expressing the HYR gene in cereal crops, such as maize, wheat and rice, may lead to increased grain yields by way of increased biomass, increased water use efficiency and abiotic stress tolerance.
