Abstract: The invention relates to the isolation and characterization of a maize gene, RAMOSA3 (RA3), responsible for meristem development and inflorescence development including branching. The gene, gene product, and regulatory regions may be used to manipulate branching, meristem growth, inflorescence development and arrangement, and ultimately to improve yield of plants. The invention includes the gene and protein product as well as the use of the same for temporal and spatial expression in transgenic plants to alter plant morphology and affect yield in plants. The invention also includes the gene and protein product for SISTER OF RAMOSA3 (SRA).
