Figure 1From: Exploring the evolutionary route of the acquisition of betaine aldehyde dehydrogenase activity by plant ALDH10 enzymes: implications for the synthesis of the osmoprotectant glycine betainePhylogenetic analysis of plant ALDH10 enzymes. A) Unrooted phylogenetic tree that includes all identified ALDH10 protein sequences showing the taxonomic group to which they belong. B) Monocot and non-flowering plant ALDH10 sequences. C) Eudicot ALDH10 sequences. Indicated are the presence/absence of a peroxisomal-targeting signal PST1 that fits to the consensus sequence (S/A/C)-(K/R/H)-(L/M) (in red and underlined) as well as the amino acid residue and codon at position equivalent to 441 of SoBADH. The tree was inferred from 500 replicates using the ML method [61]. The best tree with the highest log likelihood (-32886.4851) is shown. Similar trees were obtained with MP, ME and NJ methods. The analysis involved 131 amino acid sequences (122 from plants and 9 from non-plants). In panel A the branches of the unrooted tree are drawn to scale, with the bar length indicating the number of substitutions per site. In panels B and C only the branch topology is shown. The proportion of replicate trees in which the associated taxa clustered together in a bootstrap test (500 replicates) is given next to the branches. Branches with a very low bootstrap value (<20%) are collapsed. For each sequence, the accession number and the name assigned in published papers (in the case of proteins previously studied) are given. X indicates an unidentified amino acid/nucleotide.Back to article page
