Phylogenetic analysis of FT/TFL1-like genes in legumes and Arabidopsis. Neighbor-joining tree for the amino acid domain corresponding to exons 2, 3, and 4 (118 characters) aligned with ClustalX and rooted at the midpoint is shown. The bootstrap values are indicated as a percentage above each branch. Ps, garden pea; Mt, M. truncatula; Lj, L. japonicus; Gm, soybean. Sequence accession numbers are: MtBFT (AC146807); MtMFT (TC81061); MtFTLa (AC123593a); MtFTLb (AC123593b); MtFTLc (AC123593c).
