Abstract：
:Biological functions of transcribed spacer regions in eucaryotic pre-rRNAs remain elusive so far. Utilization of the comparative approach to analyse their secondary structure has been impeded by the extensive sequence divergence observed among most of the specimens available to date. However, we have taken advantage of the recent derivation of a set of largely similar sequences for different schistosome species to look for the presence of constrained secondary structures within the internally transcribed spacer 2 (ITS2). We show that several common features of secondary structure are shared by these species despite sequence variation, with some of them supported by compensatory changes, suggesting a significant role of ITS2 as an RNA domain during ribosome biogenesis.
