Genome-Wide Analysis of Nitrate Transporter (NRT/NPF) Family in Sugarcane Saccharum spontaneum L.

Posted: August 02, 2021


Plants take up nitrate using transmembrane proteins of the Nitrate Transporter (NRT)/Peptide Transporter family (NPF). Understanding nitrogen uptake, translocation, and utilization is key to improve nitrogen-use efficiency (NUE).


Researchers conducted a large, comprehensive genome-wide analysis of NRT/NPF genes in S. spontaneum, which included a BLAST search, phylogenetics, gene structure, protein motif analysis, and RNA-seq data analysis.


  • Identified 178 NPF genes, 20 NRT2 genes and NRT3 genes.
  • Both SsNPF and SsNRT3 genes showed diversified gene structures and expression patterns, suggesting the possibility to fine-tune the homeostasis of nitrate to cope with the changing environment.
  • The NRT/NPF genes identified provide the basis for further research of nitrate transporter functions in sugarcane to help optimize nitrogen management in bioenergy crops.
