Plant nitrogen, as a nutrient, is of great significance for plant growth and development. In recent years, the functional regulation of nitrogen uptake and transport related genes has been widely studied. Among them, NLP(Nin-like protein) transcription factor subfamily in RWP -PK family responds to nitrogen starvation and plays a central role in the regulation of plant nitrogen signal. We identified 19 NLP genes, including JTY(7), LWM(6) and F106(6). all genes were divided into 2 subfamilies, all genes were divided into 16 subfamilies.
