Figure 3.

Of 32 deeply conserved snoRNA clans, three (SNORD29, SNORD33, SNORD61) contain two or more families that can independently be placed in the LECA. Closer inspection of predicted function (Additional file 1: Table S2) indicates that families within clans target orthologous sites, suggesting that clans are a product of the model building process in Rfam and do not reflect duplication events. Colored bars delineate eukaryote supergroups shown in Figure‚ÄČ 2.
