NLP7 (NIN-LIKE-PROTEIN 7) is the major transcriptional factor responsible for the primary nitrate response (PNR), but the role of its homolog, NLP6, in nitrogen signaling and the interplay between NLP6 and NLP7 remain to be elucidated. In this study, we show that, like NLP7, nuclear localization of NLP6 via a nuclear retention mechanism is nitrate dependent, but nucleocytosolic shuttling of both NLP6 and NLP7 is independent of each other. Compared with single mutants, the nlp6nlp7 double mutant displays a synergistic growth retardation phenotype in response to nitrate.

- Nitrate signaling significantly enhances plant growth when nitrate availability is limited, improving crop production efficiency.
- The study identifies NLP2 as an important transcriptional regulator that works alongside NLP7, sharing key features and target genes necessary for nitrate response.
- NLP2 specifically regulates carbon and energy-related processes in response to nitrate, demonstrating how NLP2 and NLP7 collaborate in a complex network that connects nitrogen assimilation with overall plant metabolism and growth.
Nitrate is both an important nutrient and a signalling molecule for plants. Although several components of the nitrate signalling pathway have been identified, their hierarchical organization remains unclear. Here we show that the localization of NLP7, a member of the RWP-RK transcription factor family, is regulated by nitrate via a nuclear retention mechanism.
