Phylogenetic analysis of Arabidopsis PLL amino acid sequences. For each gene, the Arabidopsis Genome Initiative (AGI) designation is given along with the PLL designation given in this study. The number of ESTs for each gene found in the NCBI database is indicated at right. The Pec_lyase_C domain is indicated as a green oval. The amino-terminal signal peptide is represented by a yellow rectangle. The Pec_lyase_N domain is indicated as a blue rectangle. The predicted carboxyl-terminal glycosyl-phosphatidylinositol (GPI) anchor site in PMR6 (PLL13) is indicated by a red rectangle. Bootstrap values are shown above nodes and indicate how consistently the data support the given taxon bipartition.
