Abstract:
1. A process for the increase in yield of a plant, which comprises reducing or deleting the expression of an oligopeptide transporter protein in a plant, wherein the reducing or deleting comprises: a) introducing into a plant a nucleic acid molecule encoding a ribonucleic acid sequence, which is able to form a double-stranded ribonucleic acid molecule, whereby the sense strand of said double-stranded ribonucleic acid molecule has a homology of at least 80% to a nucleic acid sequence encoding the protein of SEQ ID NO: 2 or comprises a fragment of at least 20, 21, 22, 23, 24 or 25 bases of said nucleic acid sequence, and whereby the antisense strand of the double-stranded ribonucleic acid molecule is complementary to said sense strand; b) introducing into a plant an antisense nucleic acid molecule, whereby the antisense nucleic acid molecule is antisense to the full length of the transcribed mRNA of a protein encoded by a nucleic acid sequence selected from the group consisting of c) introducing into a plant a ribozyme which specifically cleaves a nucleic acid molecule conferring expression of a protein having the biological activity of a protein encoded by a nucleic acid sequence selected from the group consisting of d) introducing into a plant the antisense nucleic acid molecule characterized in (b) and the ribozyme characterized in (c); e) introducing into a plant a sense nucleic acid molecule conferring the expression of a nucleic acid sequence comprising f) introducing into a plant an expression construct conferring the expression of any one of (a) to (e); and expressing said nucleic acid molecule, wherein said expression results in increased plant yield.
