The present invention concerns a method for increasing plant yield relative to corresponding wild type plants. More specifically, the present invention concerns a method for increasing plant yield comprising introducing into a plant a nucleic acid encoding a cyclin D3 (CYCD3) polypeptide under the control of a promoter capable of preferentially expressing the nucleic acid in the endosperm of seeds. The present invention also concerns plants comprising an isolated nucleic acid encoding a CYCD3 polypeptide under the control of a promoter capable of preferentially expressing the nucleic acid in the endosperm of seeds, which plants have increased yield relative to corresponding wild type plants. The invention also provides constructs useful in the methods of the invention.

La présente invention concerne un procédé permettant d'accroître le rendement d'une plante par rapport à des plantes de type sauvage correspondantes. Plus particulièrement, cette invention concerne un procédé permettant d'augmenter le rendement d'une plante, qui consiste à introduire dans une plante un acide nucléique codant pour un polypeptide cycline D3 (CYCD3) sous le contrôle d'un promoteur capable d'exprimer de préférence cet acide nucléique dans l'endosperme de graines. La présente invention concerne aussi des plantes comprenant un acide nucléique isolé codant pour un polypeptide CYCD3 sous le contrôle d'un promoteur capable d'exprimer de préférence cet acide nucléique dans l'endosperme de graines, ces plantes possédant un rendement accru par rapport à des plantes de type sauvage correspondantes. Cette invention concerne enfin des construits qui conviennent dans les procédés de cette invention.
