Table 2 Major clades in the SMXL family

From: Strigolactone synthesis is ancestral in land plants, but canonical strigolactone signalling is a flowering plant innovation

  1. Table showing major clades in the SMXL family, as defined at the level of major taxonomic groups. Almost all sequences in the family unambiguously group into one of these clades. Within some clades, there are major sub-clades where the lineage has been duplicated; these are listed at the right. Our analysis suggests that seed plant SMXL proteins group into two super-clades, SMAX1 and SMXL4, as indicated on the left of the table
