Phylogenetic analysis of PUB genes in Arabidopsis, rice, and barley. Class II genes were clustered and colored with blue. Class IV genes were clustered and colored with red. Class V genes were clustered and colored with green. Class VI genes were not clustered and indicated with incarnadine colored marks. Red asterisks indicate barley genes in Class VI. Pink asterisks show HvPUB24 and HvPUB55 gene pair
