Figure 3

Phylogenetic analysis and schematic diagram for intron/exon gene structures of PLD genes in Arabidopsis, rice, Poplar and Grape. The Phylogenetic tree was constructed based on a complete protein sequence alignment of PLDs in the four higher plants by the neighbor-joining method with bootstrapping analysis (1000 replicates). The numbers beside the branches indicate the bootstrap values that support the adjacent node. The green boxes and gray lines in the gene structure diagram represent exons and introns, respectively. Gene models are drawn to scale as indicated on bottom. The gene pairs marked by the blue box represent the 13 paralogous gene pairs.
