摘要 |
The present invention provides a transformed plant having free-amino acid content increased by introducing phosphoenolpyruvate carboxylase (PEPC) genes, and also a progeny thereof and a seed thereof. Namely, the transformed plant has a nucleic acid construct containing PEPC gene introduced therein, wherein phosphoenolpyruvate carboxylase encoded by the PEPC gene does not require phosphorylation for the activation thereof and/or is independent of acetyl CoA. In particular, the present invention provides a transformed plant comprising a nucleic acid construct containing a nucleic acid molecule encoding Synechococcus vulcanus PEPC or a nucleic acid construct containing a nucleic acid molecule encoding a protein having PEPC activity which has at least 80% of nucleotide sequence homology to said gene.
