a Phylogenetic tree of ZTL and FKF1 genes. Due to the lack of complete sequence information for the TaZTLb gene, the partial wheat ZTLb CDS from PUT43520 was used to represent wheat. Since P. patens does not contain a true orthologue of ZTL or FKF1, the root was placed on the FKF1 family branch. b Phylogenetic trees of the ELF4-like family. Due to the lack of complete CDS data for the TaELF4-like3, the partially related cDNA from PUT145474 was used to represent this wheat branch. In constructing the trees, all gaps and missing data were eliminated from sequence alignments. Genes that do not follow expected topology are shown in grey. Evolutionary distances are presented in number of base substitutions per site. Barley genes are highlighted with a box
