Abstract: The invention relates to a method of enhancing the seed yield and promoting the growth of monocotyledonous or dicotyledonous plants by overexpression of TMT (tonoplast monosaccharide transporter) protein in osogenic or transgenic plant cells. The invention further concerns a transgenic plant having the property of an enhanced seed yield and increased growth as compared with the wild type, comprising a nucleotide sequence which codes for a TMT (tonoplast monosaccharide transporter) protein, as well as a regulatory nucleotide sequence, operably linked therewith, for the control of an increased gene expression of the TMT protein in the plant cells of the transgenic plant. It further relates to the use of the transgenic plant for the cultivation or production of cultivated plants or useful plants, or biomass, oils or proteins produced therefrom.
