Fig 2. Multiple sequence alignment of amino acid (aa) sequences of HD from different classes.

The representatives of each class from Arabidopsis thaliana (AT), Cicer arientinum (Ca), Glycine max (Glyma), Cajanus cajan (C. cajan), Medicago truncatula (Medtr) and Lotus japonicus (LjSGA, chr) have been shown. The alignment was obtained using CLUSTALX and conserved amino acids of different physicochemical properties are highlighted in different shades using the Jalview software. Atypical aa residues are also shaded and the positions of three alpha helices are indicated at the bottom of the diagram.
