PLANTS HAVING ENHANCED YIELD-RELATED TRAITS AND METHOD FOR MAKING THE SAME

摘要

The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an OsRSZ33 RRM polypeptide, a growth-related protein (GRP) having at least 25% amino acid sequence identity to SEQ ID NO: 251, or a ZPR polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an OsRSZ33 RRM polypeptide, a growth-related polypeptide as defined herein, or a ZPR polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides unknown OsRSZ33 RRM-encoding nucleic acids, GRP-encoding nucleic acids, or a ZPR polypeptide, and constructs comprising the same, useful in performing the methods of the invention.

1. A method for enhancing a yield-related trait in a plant relative to a control plant, comprising modulating expression in a plant of a nucleic acid encoding a growth-related protein (GRP) or a Little-Zipper (ZPR) polypeptide, wherein:
(a) said growth-related protein (GRP) has at least 25% sequence identity to the amino acid sequence of SEQ ID NO: 251; or (b) said ZPR polypeptide comprises a Leucine Zipper (ZIP) domain that is six heptads in length.
