From: Analysis of MAPK and MAPKK gene families in wheat and related Triticeae species
Phylogenetic distribution of Triticeae and Brachypodium MKKs. PK domains of wheat, barley, rye and triticale MKKs were aligned with BdMKKs, and the tree rooted with HsMEK1. Descriptive gene names are followed by chromosome number when available. Accessions used in the analysis are marked in bold in Additional file 3. BdMKKs are bolded in tree to visually separate them from the sequences identified herein. Only accessions with complete PK domains are included in the analysis. MKKs are divided into four clades (a, b, c, and d). MEME analysis shows amino acid distribution of the NTF-2 domain conserved in the C-terminal extensions of MKK3s. An additional tree is presented for clade D (MKK10s), where the Triticeae species were aligned with Brachypodium, rice (Os) and maize (Zm) and the tree rooted with HsMEK1. Font colours are used to distinguish MKK10 orthologues from different species: MKK10–1 (red), MKK10–2 (orange), MKK10–3 (blue), MKK10–4 (purple), MKK10–5 (teal)
