amino acids or amino acid analogues added singly to the induction medium have a similar effect : i.e . when the induction of nitrate reductase is inhibited in the root tips ( lysine , canavanine , azaserine , azetidine-2-carboxylic acid , dl-4-azaleucine , asparagine , and glutamine ) , that inhibition is more severe in mature root sections .
