Evolution of dicot XIPs. A likely scenario for the evolution of dicot XIPs. The evolutionary events are indicated at the point where the XIPs diverged. Dicot XIPs evolved from fungi and moss through substitutions at ar/R selectivity filter, insertion/deletion of loop C and loss of an intron. However, small and weakly polar residues occurring at the helix-helix interface are highly group-conserved.
