ABSTRACT
During zebrafish development, an early type of rRNA is gradually replaced by a late type that is substantially different in sequence. We applied RiboMeth-seq to rRNA from developmental stages for profiling of 2'-O-Me, to learn if changes in methylation pattern were a component of the shift. We compiled a catalog of 2'-O-Me sites and cognate box C/D guide RNAs comprising 98 high-confidence sites, including 10 sites that were not known from other vertebrates, one of which was specific to late-type rRNA. We identified a subset of sites that changed in methylation status during development and found that some of these could be explained by availability of their cognate SNORDs. Sites that changed during development were enriched in the novel sites revealed in zebrafish. We propose that the early type of rRNA is a specialized form and that its structure and ribose methylation pattern may be an adaptation to features of development, including translation of specific maternal mRNAs.
