Abstract: A transgenic land plant that expresses a polyhydroxy alkanoate synthase seed specifically, with cytosolic localization is disclosed. The plant includes a nucleic acid encoding the polyhydroxy alkanoate synthase and a seed-specific promoter operably linked to the nucleic acid. The seed-specific promoter drives expression of the polyhydroxy alkanoate synthase in cytosol of cells of seeds of the plant. The polyhydroxy alkanoate synthase includes a catalytic domain. The polyhydroxy alkanoate synthase does not include any sequence positioned to mediate translocation of the catalytic domain across any membrane of the cells, thereby resulting in the polyhydroxy alkanoate synthase being expressed seed specifically, with cytosolic localization.
