Identification of PEBP-related genes from several members of Euphorbiaceae. (A) Phylogenetic analysis of PEBP family proteins in plants. A Neighbor-Joining phylogenetic analysis of multiple members of the PEBP family from several plant species. Bootstrap values for 1,000 resamplings are shown on each branch. (B) Genomic organization of FT genes from Jatropha curcas (Jc), Arabidopsis thaliana (At), Beta vulgaris (Bv), Ricinuscommunis (Rc) and Manihotesculenta (Me). Boxes and lines represent exonic and intronic regions, respectively. Numbers refer to the length of DNA in base pairs. (C) Age-dependent expression of JcFT in Jatropha leaves. The newly formed leaf upon emergence of the first inflorescence was considered as +1. JcFT RNA levels from leaves at three different positions (+3, +5, +9) were measured and normalized with respect to ubiquitin mRNA. Values are mean ± SD (n = 3).
