Compositions and methods for altering the levels of reversibly glycosylated polypeptide (RGP) in plants are provided. The present invention recognizes that by altering the level of expression of RGP, plants and seeds having beneficial qualities can be obtained. The invention involves controlled suppression of RGP expression to obtain plants and seeds having decreased amounts of hemicellulose and arabinose. Controlled suppression of RGP, particularly in vegetative tissues and seeds, leads to plants with desirable characteristics, including altered cell wall structure, reduced grain fiber content, increased seed protein, increased oil content, and altered arabinoxylan or xyloglucan levels. Compositions of the invention include constructs for the suppression of RGP and transformed plants and seeds having the altered phenotype of the invention.
