摘要：
Methods and compositions for modulating expression of knotted1 (kn1) polypeptides in seed and reproductive tissue are provided. Polynucleotide sequences encoding knotted1 transcription factor polypeptides are expressed in a spatially and/or temporally regulated manner with expression preferentially in developing flowers, pods, ears and/or seeds, or to other reproductive structures during flowering and seed development, to create a sequestered effect resulting in plants that produce increased yield and may have greater flower, pod, ear and/or seed retention. Transformed plants, plant cells, tissues and seed are also provided.
