Abstract
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.
Claims12
1-63. (canceled)
A transgenic plant comprising an exogenous polynucleotide which encodes a polypeptide with an amino acid sequence that is at least 90% identical to the full length amino acid sequence of any one of SEQ ID NOs 1-4, wherein the polynucleotide is operably linked to a promoter capable of directing expression of the polynucleotide in a cell of the plant.
