The maximum likelihood (ML) phylogenetic tree for CKX proteins in Arabidopsis thaliana (AtCKX), Oryza sativa (OsCKX) , Triticum aestivum (TaCKX), and Zea mays (ZmCKX). The tree was rooted using CKX protein from Rhodococcus fascians (RfCKX). Node values are percentages of bootstraps generated with 1000 bootstrap replicates.
