Identification and characterization of an glutamine dumper 1 phenotype (gdui1) in arabidopsis

摘要

The present invention is directed to a novel plant phenotype, designated GLUTAMINE DUMPER 1 (GDU1), a nucleic acid sequence expressed in plants demonstrating the GDUI1 phenotype and the corresponding amino acid sequence. Also provided are plant cells and plants that exhibit modified GDUI1 expression. The invention is further directed to the GDUI1 promoter, which is capable of directing vascular tissue specific expression of heterologous coding sequences.
