| Outline of Final Research Achievements |
Nitrate-responsive gene expression plays a key role in adaptation to diverse nitrogen conditions in plants. We previously identified NLPs as transcription factors responsible for nitrate-responsive gene expression. In this study, we analyzed the molecular mechanisms underlying NLP-mediated and nitrate-responsive gene expression in Arabidopsis. By DNA microarray analysis, we found that NLP transcription factors are master regulators responsible for expression of most of nitrate-regulated genes in Arabidopsis. We also found that phosphorylation of NLP transcription factors is a key for nitrate signaling and induction of NLP activity.
