  1. Sixteen gene families were analyzed. For each gene family, the number under the species with the larger number of genes is highlighted in bold. In most cases there were more Arabidopsis members than Physcomitrella members. ND (not determined); phylogenetic ambiguity prevents an accurate estimation of ancestral gene number at this time.
