Phylogenetic analysis, conserved motifs and gene structures of GhNAT genes. A Phylogenetic tree of GhNAT genes. B Conserved motifs of GhNAT proteins. Twenty conserved motifs are represented by different color boxes. C Exon–intron organization analyses of GhNAT genes. Yellow boxes mean Untranslated Regions (UTR), Exons and introns are distinguished by green boxes and black lines, respectively
