Zea mays nlp transcription factor zmnlp5 and use thereof

Abstract

The present invention clones a gene ZmNLP5 from maize, which plays an important regulatory role in nitrogen assimilation, and the open reading frame of which has a DNA sequence shown as SEQ ID NO:1. The transcription factor protein encoded by the ZmNLP5 gene has an amino acid sequence shown as SEQ ID NO:2. The uses of the maize NLP transcription factor ZmNLP5 mentioned above in promoting expression of a nitrogen metabolic key enzyme gene ZmNIR1.1, in promoting expression of a nitrogen metabolic key enzyme gene ZmNIR1.2, in promoting expression of a nitrogen metabolic key enzyme gene ZmNR1.1, in promoting expression of a nitrogen metabolic key enzyme gene ZmNR1.2, in improving nitrogen assimilation in maize, and in promoting elongation growth of maize root in deficient nitrogen environment are further provided.
