Publication number: 20160010104Abstract: The present invention concerns a method for enhancing yield-related traits in plants by modulating expression of a particular type of NAC transcription factor, an AP2-2 polypeptide, or an APETELA2-70-like (AP2-70-like) polypeptide 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, 51, 53, 55, 57 or 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, AP2-2 polypeptide, or 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.Type: ApplicationFiled: September 23, 2015Publication date: January 14, 2016Inventors: Yang Do Choi, Ju Kon Kim, Baek Hie Nahm, Jin Seo Jeong, Se-Jun Oh, Chang-Deok Han, Sung Han Park, Pil Joong Chung
