Maximum likelihood phylogenetic structure and motifs of acyl-CoA-binding protein (ACBP) genes in Hordeum vulgare L. (a) Phylogenetic tree and HvACBP subfamilies, further divided into four groups. (b) HvACBP exon–intron organization. (c) ACBP motifs. (d) Ankyrin domains are conserved in the ANK-ACBP subfamily and the Kelch domain is conserved in the Kelch-ACBP subfamily
