(A) Phylogenetic unrooted tree of the RAV family in Arabidopsis thaliana. Analysis was done using the CLC Genomics Workbench v6.5 program; bootstrap values are indicated. (B) Amino acid sequence of four RAV members, TEM1, TEM2, RAV1 and RAV1L, with the exact location of these domains. Analysis was done using Clustal v2.1 multiple amino acid alignment; substitution rate model = WAG. Main characteristic protein domains of RAV transcription factor family include: AP2 (grey) and B3 (blue) DNA-binding domains; nuclear localization signal (NLS) in purple; and B3 repression domain (BRD) in green.
