The present invention provides crop plants and methods for improving grain yield of crop plants both under environmental stress as well as optimal conditions, as well as methods of making such plants. In particular, the present invention provides methods that result in crop plant stability under multiple environments by increasing biomass, water use efficiency and abiotic stress tolerance. Embodiments provide a transgenic crop plant comprising a chimeric gene that comprises: a transcription regulatory sequence active in plant cells and a nucleic acid sequence encoding a HYR protein, wherein such HYR protein comprises the sequence of SEQ ID 1, a sequence with at least 70% similarity to SEQ ID 1, a sequence encoding an ortholog protein, a sequence encoding a homologous protein, a functional fragment, and any combination thereof. |
