Fig. 1From: Ectopic expression of a grape nitrate transporter VvNPF6.5 improves nitrate content and nitrogen use efficiency in ArabidopsisAmino acid sequence alignment of the VvNPF6.5, AtCHL1 and OsNRT1.1B. SnapGene program was used to perform the sequence alignment. The identical residues were shaded and the dots were inserted to optimize the alignment. The putative transmembrane domains (TM) are marked with black underline and are numbered. The putative phosphorylation sites are enclosed in the red boxBack to article page
