PLANTS HAVING ENHANCED YIELD-RELATED TRAITS AND A 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 a WI12-like (WIL) polypeptide or a SAWADEE-like polypeptide or a POZ-like (Pox virus and Zn Finger) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding a WIL polypeptide or a SAWADEE-like polypeptide or a POZ-like polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown WIL-encoding nucleic acids, and constructs comprising the same, and hitherto unknown POZ-like encoding nucleic acids, 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:
(a) modulating expression in a plant of a nucleic acid encoding a SAWADEE-like polypeptide, wherein said SAWADEE-like polypeptide comprises:
(i) a homeodomain;(ii) a SAWADEE domain; and(iii) a nuclear localisation signal (NLS); or (b) modulating expression in a plant of a nucleic acid encoding a WI12-like (WIL) polypeptide, wherein said WIL polypeptide comprises one or more of the following motifs:
(i) Motif 1 of SEQ ID NO: 317;(ii) Motif 2 of SEQ ID NO: 318; and(iii) Motif 3 of SEQ ID NO: 319.
