Genome-wide identification, structural and gene expression analysis of the nitrate transporters (NRTs) family in potato (Solanum tuberosum L.).

ABSTRACT: Nitrogen (N2) is the most important source of mineral N for plant growth, which was mainly transported by nitrate transporters (NRTs). However, little is known about the NRT gene family in potato. In this study, StNRT gene family members were identified in potato. In addition, we performed StNRT subfamily classification, gene structure and distribution analysis, and conserved domain prediction using various bioinformatics tools. Totally, 39 StNRT gene members were identified in potato genome, including 33, 4 and 2 member belong to NRT1, NRT2, and NRT3, respectively. These 39 StNRT genes were randomly distributed on all chromosomes. The collinearity results show that StNRT members in potato are closely related to Solanum lycopersicum and Solanum melongena. For the expression, different members of StNRT play different roles in leaves and roots. Especially under sufficient nitrogen conditions, different members have a clear distribution in different tissues. These results provide valuable information for identifying the members of the StNRT family in potato and could provide functional characterization of StNRT genes in further research.
