Plants are sensitive to D-serine, but functional expression of the dsdA gene, encoding D-serine ammonia lyase, from Escherichia coli can alleviate this toxicity. Plants, in contrast to many other organisms, lack the common pathway for oxidative deamination of D-amino acids. This difference in metabolism has major consequences for plant responses to D-amino acids, since several D-amino acids are toxic to plants even at relatively low concentrations. Therefore, introducing an enzyme specific for… CONTINUE READING
