Six Sigma Factor Families in Geraniales and Arabidopsis.

The unrooted amino acid-based ML tree was generated using 178 complete SIG sequences identified from 27 species of Geraniales and Arabidopsis. The ML tree (-lnL = −65001.9) topology parsed the 178 sequences into six subgroups (enclosed in labeled circles). Scale bar represents the number of amino acid substitutions per site. Numbers at nodes are bootstrap support values.
