^aSpecies abbreviations are: Cr, Chlamydomonas reinhardtii; Ol, Ostreococcus lucimarinus; Ot, O. tauri; Cv, Chlorella vulgaris; Vc, Volvox carteri; Pp, Physcomitrella patens; Sm, Selaginella moellendorffii; Os, Oryza sativa; Zm, Zea mays; Sb, Sorghum bicolor; Vv, Vitis vinifera; At, Arabidopsis thaliana; Pt, Populus trichocarpa; Gm, Glycine max.
^bThe percentage of proteins with at least one Pfam domain predicted at an E-value cutoff of 10^-2.
^cDenotes the percentages of domain architectures that are unique to each species.
^dThe architectures with 4 or more domains.
Note that overall predicted architectures are categorized into single-domain, double-domain, tripe-domain and > = 4-domain architectures. The proportions of overall predicted architectures in each genome should be the sum of the proportions of these above mentioned four categories.
