GENES THAT INCREASE PLANT OIL AND METHOD FOR USING THE SAME

摘要

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.

主权项

1. A plant which expresses a chimeric protein, said chimeric protein comprising a transcription factor fused to a repressor domain sequence that converts said transcription factor into a transcription repressor,
wherein said transcription factor is selected from the group consisting of (a) and (b): (a) a protein comprising the amino acid sequence of SEQ ID NO: 4; and (b) a protein comprising the amino acid sequence of SEQ ID NO: 4 but in which 1-20 amino acids have been deleted, substituted, added or inserted, and wherein the seeds of said plant exhibit an increase in weight, an increase in amount of fat and oil, or an increase in fat and oil content, in comparison to a wild-type plant not expressing said chimeric protein.
