Based on Tartary buckwheat genome database, 72 genes of NAC family in Tartary buckwheat were identified and screened by using comparison program. Genetic structure analysis showed that all the 71 genes, except FtPinG0002967400.01.t01, contained introns. The prediction and analysis of physical and chemical properties showed that 72 protein sequences had NAC domain. There were 7 conserved motifs in 72 NAC genes, which were distributed on 8 chromosomes of Tartary buckwheat. Thirty-three NAC genes were differentially expressed during seed development. Phylogenetic analysis showed that 72 NAC genes and the NAC genes of arabidopsis thaliana could be divided into 9 subfamilies.
