摘要： The present invention concerns a method for enhancing yield-related traits in plants by modulating expression of a particular type of NAC transcription factor in plants. The particular type of NAC transcription factor is one having an amino acid sequence, which when used in the construction of a NAC phylogenetic tree, tends to cluster with the group of NACs comprising the amino acid sequence represented by SEQ ID NO: 2, SEQ ID NO: 51, SEQ ID NO: 53, SEQ ID NO: 55, SEQ ID NO: 57 or SEQ ID NO: 59 rather than with any other NAC group. The present invention also concerns plants having modulated expression of a nucleic acid encoding such a NAC transcription factor, which plants have enhanced yield-related relative to control plants. The present invention further concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an AP2-2 polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an AP2-2 polypeptide, which plants have enhanced yield-related traits relative to control plants. The present invention further concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an APETELA2-70-like (AP2-70-like) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an AP2-70-like polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown NAC, AP2-2 and AP2-70-like-encoding nucleic acids, and constructs comprising the same, useful in performing the methods of the invention. The invention also provides constructs useful in the methods of the invention.
