Abstract
L-threonine is produced by incorporating into a recipient microorganism of the genus Escherichia which does not require L-threonine for growth, a plasmid, in which a deoxyribonucleic acid fragment which possesses genetic information relating to L-threonine synthesis obtained from a mutant resistant to .alpha.-amino-.beta.-hydroxy valeric acid of the genus Escherichia, has been inserted.
