Identification of poplar SOC1-like proteins. (A) Phylogenetic tree analyses of MADS-box proteins from Arabidopsis and poplar. Maximum likelihood tree obtained using the RAxML tool with 1,000 bootstrap replicates. The right panel indicates the color code of the clades and bootstrap values. Clades are named FLOWERING LOCUS C (FLC), APETALA1/FRUITFUL (AP1/FUL), SEPALLATA (SEP), AGAMOUS-LIKE 6 (AGL6), SOC1, AG, AGL12, SVP, AGL15, AGL17, AP3, PISTILLATA (PI), and TRANSPARENT TESTA16 (TT16). (B) MAFF alignment of Populus, Arabidopsis, rice, and maize SOC1-like proteins. The alignment shows part of the K domain (green ink) and the SOC1 motif (red ink). Black boxes indicate identical amino acids. Gray boxes indicate conservative amino acid substitutions.
