The present invention relates to the isolation and identification of a
short integuments protein and the nucleic acid which encodes such protein.
The invention also relates to an expression vector containing the encoding
nucleic acid and methods whereby plant fertility, fecundity and flowering
time are increased or decreased by transformation of plants with that
nucleic acid or variants thereof. The present invention also relates to
transgenic cells, plants, and seeds containing the short integuments gene
of the present invention.
