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.

Decreasing nitrite content in tobacco via expression of a nitrite reductase

The invention relates to the isolation and characterisation of novel expansin gene sequences from heterologous and homologous tree species and re-introducing such novel genes into trees so as to alter expansin levels. Six novel genes have been identified.has also been transformed using the cucumber EX29 sequence (GenBank, Accession No. U30382-known as Cs-EXP1) (SEQ. ID. NO: 9). A change in the plant height and internode length was observed compared with control plants.
