Phylogenetic analysis of GDSL-motif lipase/hydrolase family proteins. The Arabidopsis genes (AGI numbers, www.arabidopsis.org, in black) are those showing >2-fold enrichment in epidermal peels relative to whole stem tissue (Suh et al., 2005). The blue TIGR plant transcript assembly numbers (plantta.jcvi.org) and NCBI EST accessions were identified as tomato transcripts enriched in the peel relative to tomato flesh (Mintz-Oron et al., 2008). AgaSGNH (purple) was identified as an epidermal-specific transcript in Agave americana (Reina et al., 2007). SGN unigenes (www.solgenomics.net) described in the current study are shown in red and are underlined if they were identified with confidence (spectra matching two or more peptides, see text). Bootstrap support of the four arbitrarily numbered clades is indicated in italics (500 replications). The bootstrap support of Clade III increases to 92% if the outlying At3g11210 and TC174299 sequences are discarded. Branch lengths are proportional to distance, as indicated by the scale legend.
