A gene having novel functions is searched for, by which plant weight (that is, biomass level) can be increased and by which substance productivity can be increased or decreased. A chimeric protein is expressed in which a transcriptional factor comprising the amino acid sequence shown in SEQ ID NO: 2, 4, or 6 is fused to a functional peptide that converts an arbitrary transcriptional factor into a transcriptional repression factor.

Gene for increasing plant weight and method for using the same

This invention is intended to be used to search for a transcription factor having novel functions of increasing the weight of an individual plant, increasing the weight of a given tissue per individual plant, or improving the productivity of a given substance per individual plant and to improve such properties in the plant. The weight of an individual plant is increased, the weight of a given tissue per individual plant is increased, the productivity of a given substance per individual plant is improved, or the content of a given substance per given tissue of a plant is increased via expression of a transcription factor that has been modified to suppress transcription accelerating activity.
