Conserved C-terminal domains. A: C-terminal amino acid (aa) alignment of HvNAC033 and its closest homologues from Brachypodium, rice, and Arabidopsis. Three different characters are used to indicate conservation: '*' indicating full conservation of aa, ':' indicating strong conservation (non-identical aa, but with highly similar physico-chemical properties) and '.' indicating weak conservation (non-identical aa, but with somewhat similar physico-chemical properties). B: Same as A, but for HvNAC011 and its homologues.
