Abstract

Protein accounts for approximately 40 % of the dry weight of a soybean seed; how­ ever, soy protein is deficient in both cysteine and methionine. To overcome this sulfur deficiency, animal feeders supplement soy protein rations with costly methio­ nine, which is more stable than cysteine. To alleviate the need for methionine supplementation, we mutagenized seeds and selected genetic soybean lines, the protein of which is enriched approximately 20 % for both cysteine and methionine. Animal rations prepared from these genetic lines should not require methionine supplemen­tation.
