The role of protein-protein interactions mediated by the PB1 domain of NLP transcription factors in nitrate-inducible gene expression.

Protein-protein interactions mediated by the PB1 domain of NLP transcription factors are necessary for full induction of nitrate-dependent expression of target genes in planta. The PB1 domains of NLP transcription factors may act on gene expression from chromosomal DNA via homo- and hetero-oligomerization in the presence of nitrate.
