Distance-Based Gene Tree of the SHD and WA Domains Manually Fused Together for Arabidopsis, M. truncatula, P. trichocarpa, O. sativa, and P. patens.

We designated SCARs within the Arabidopsis SCAR2/4 clade as the A clade and those within the SCAR1/3 clade as the B clade. The numbering scheme for the SCAR genes is not intended to reflect ancestral relationships. With the exception of Arabidopsis SCARL that contains only an SHD domain, SCAR-like proteins from other species that did not contain both a SHD and WA domain were not included in this tree. The resulting tree had a minimum evolution score of 567.3. Corresponding accession numbers for each gene can be found under accession numbers and the corresponding Nexus alignment as Supplemental Data Set 1 online.
