Abstract
The present disclosure concerns methods and compositions relating to UXS polypeptides and/or nucleic acids encoding UXS polypeptides. In certain claims, the methods and compositions are of use to improve digestibility and/or ease of grain processing. Such improvements relate to a modulation in arabinoxylan and/or hemicellulose content in transgenic plants. Such plants can, for example, comprise one or more nucleic acid sequences that inhibit expression of one or more UDP-Xylose Synthase (UXS) genes.
Claims4
A method for reducing arabinoxylan levels in a plant cell, comprising:
- (a) transforming the plant cell with at least one isolated polynucleotide comprising a member selected from the group consisting of:
- (i) a polynucleotide having at least 95% sequence identity to SEQ ID NO:
- 17;
- wherein the % sequence identity is determined over the entire length of the sequence by the GAP algorithm using default parameters, and
- (ii) a polynucleotide comprising SEQ ID NO:
- 17;
- and
- (b) growing the transformed plant cell to reduce arabinoxylan levels in the plant cell.
Dependencies are inferred from the claim text.
