Methods of controlling fructan synthesis in plants

摘要

The present invention relates to plants with increased levels of water soluble carbohydrates, particularly fructan, in the stem and leaf sheath. The present invention also provides methods of identifying and/or producing these plants. In particular, the present invention relates to a novel class of polypeptides designated MYB13 which upregulate the expression of enzymes involved in fructan synthesis. The present invention further relates to a novel promoter element that can be used to express genes predominantly in the stem and leaf sheath during the early reproductive stage of a plant.
