METHODS OF MODULATING SEED AND ORGAN SIZE IN PLANTS

摘要

This invention relates to the expression a DA1 protein with a mutation that disrupts or inactivates the LIM domain or the LIM-like domain within cells of a plant. This may increase the yield or enhance a yield-related trait of the plant. Methods, plants and plant cells are provided.

1. A method of increasing the yield of a plant or enhancing a yield-related trait in a plant comprising;
expressing a DA1 protein within cells of said plant, wherein said the amino acid sequence of the DA1 protein comprises a mutation that disrupts or inactivates the LIM domain or the LIM-like domain of the DA1 protein, wherein the LIM domain of the DA1 protein comprises one or more sequence alterations relative to the wild-type LIM domain of SEQ ID NO: 1 which inactivate the LIM domain; or the LIM-like domain of the DA1 protein comprises one or more sequence alterations relative to the wild-type LIM-like domain of SEQ ID NO: 28 which inactivate the LIM-like domain.
