Additional file 1: of Genome-wide analysis of starch metabolism genes in potato (Solanum tuberosum L.)

Phylogenetic analysis of gene families involved in starch metabolism. Tree calculation was based on a global alignment with free end gaps, BLOSUM62 cost matrix and Jukes-Cantor genetic distance model. The tree was built by the Geneious 5.5.6 Tree Builder module employing a neighbour-joining method. a) alpha-amylases, b) beta-amylases, c) phosphoglucomutases, d) starch synthases, e) sucrose synthases, f) glucose-6-phosphate-phosphate translocators, g) starch branching enzymes, h) ADP-glucose pyrophosphorylases, i) isoamylases. The scale bar at the bottom represents the average substitutions per amino acid site. (PDF 110Â kb)
