Evolutionary History

The size of the gene family is two, and includes FAM210A and FAM210B. Gene duplication seems to have occurred when plants diverged from protists. The most distant ortholog found was Populus trichocarpa, also known as the black cottonwood tree. [12] The unrooted phylogenetic tree below demonstrates this divergence. [13] All of the organisms in the tree can also be found in the ortholog table above.
