Supplementary Fig. S1.
Multiple sequence alignment of ASK proteins of Arabidopsis thaliana. Residues aligned with ASK1 Cys37, Cys59 and Cys118 are boxed. Phylogenetic tree with bootstrap test results (1000 replicates) for the alignment of the complete 21 sequences is shown. Shaded residues correspond to conservation higher than 50%; more intense shading represent higher degree of conservation.
