The present invention provides methods for identifying nucleic acid and
polypeptide sequences which may be associated with a commercially
relevant trait in plants, specifically, so-identified nucleic acids and
polypeptide sequences for yield gene EG307. Sequences thus identified are
useful in enhancing commercially desired traits in domesticated plants or
wild ancestor plants, identifying related nucleic acid sequences,
genotyping a plant, and marker assisted breeding. Sequences thus
identified may also be used to generate heterologous DNA, transgenic
plants, and transfected host cells.
