Phylogenetic tree of acyl-ACP synthetases of photosynthetic organisms including two Lacs sequences of Arabidopsis as outgroup (clade V). The branch lengths of the tree are proportional to the calculated divergence. The 0.1 scale represents 10% sequence divergence, calculated as estimated numbers of replacement. The numbers indicate the confidence levels for various branches as determined by bootstrap analysis (Felsenstein, 1989). Abbreviations are given in Table I.
