Plant families with or without putative F6´H1 orthologs. A BlastP search was performed with amino acids 151 to 309 of A. thaliana F6’H1 in the NCBI (http:// ncbi.nlm.nih.gov) and Phytozome (http://phytozome.org) databases (maximum target sequences: 5000). Sequences were selected as putative orthologs when a reverse BlastP search yielded AtF6’H1 or AtF6’H2 as the top hit. Species with putative orthologs where then placed into a phylogenetic tree based on the taxonomic classification in NCBI. Shown are families with (green branches) or without (red branches) putative F6’H1 orthologs. Species representing the families are: Arabidopsis thaliana (Brassicaceae), Carica papaya (Caricaceae), Tarenaya hassleriana (Cleomaceae), Gossypium raimondii (Malvaceae), Ruta graveolens (Rutaceae), Manihot esculenta (Euphorbiaceae), Linum usitatissimum (Linaceae), Salix purpurea (Salicaceae), Morus notabilis (Moraceae), Malus domestica (Rosaceae), Cucumis sativus (Cucurbitaceae), Cicer arietinum (Fabaceae), Vitis vinifera (Vitaceae), Ipomoea batatas (Convolvulaceae), Nicotiana sylvestris (Solanaceae), Sesamum indicum (Pedaliaceae), Coffea canephora (Rubiaceae), Spinacia oleracea (Amaranthaceae), Nelumbo nucifera (Nelumbonaceae), Aquilegia coerulea (Ranunculaceae), Lilium longiflorum (Liliaceae), Triticum aestivum (Poaceae).
