Abstract
The present invention relates in one aspect to a method for producing a transgenic plant, comprising introducing into an unmodified plant an exogenous gene encoding a nitrite reductase, wherein expression of the nitrite reductase encoded by the exogenous gene reduces nitrite content in the transgenic plant relative to the unmodified plant. Also provided are transgenic plants and plant cells comprising an exogenous gene encoding a nitrite reductase, as well as associated uses, chimaeric genes and plant transformation vectors.
Claims11
A transgenic Nicotiana tabacum plant comprising:
- an exogenous gene encoding a nitrite reductase having at least 95% amino acid sequence identity to the polypeptide as defined in SEQ ID NO:3, wherein the gene encodes a protein having nitrite reductase activity and a plastid transit peptide, wherein nitrite content in the transgenic plant is reduced compared to an unmodified plant.
