Abstract
The nutritive value of lupin, an important grain legume for animal production, has been improved by the transformation of a chimeric gene specifying seed-specific expression of a sulfur-rich sunflower seed albumin (SSA). This gene encodes a protein which contains 16% methionine and 8% cysteine residues and the protein was expressed in transgenic seeds at a level of 5% of total soluble seed protein. The expression of the SSA gene in lupin seeds caused an overall increase in sulfur containing amino acids of 19%, while methionine levels were doubled. The improved nutritive value of these transgenic lupin seeds was demonstrated in feeding trials with rats, chickens, and sheep.
