Class I RNA expression in different dictyostelids
Aggregative multicellularity has evolved multiple times in diverse groups of eukaryotes. One of the most well-studied examples is the development of dictyostelid social amoebae, e.g. Dictyostelium discoideum. However, it is still poorly understood why multicellularity emerged in these amoebae while the great majority of other members of Amoebozoa are unicellular. Previously a novel type of non-coding RNA, Class I RNAs, was identified in D. discoideum and demonstrated to be important for normal multicellular development. Here we investigated Class I RNA evolution and its connection to multicellular development. Here we investigate the evolution and expression of these ncRNAs in dictyostelids.
