Exploring tRNA gene cluster in archaea

BACKGROUND Shared traits between prokaryotes and eukaryotes are helpful in the understanding of the tree of life evolution. In bacteria and eukaryotes, it has been shown a particular organisation of tRNA genes as clusters, but this trait has not been explored in the archaea domain. OBJECTIVE Explore the occurrence of tRNA gene clusters in archaea. METHODS In-silico analyses of complete and draft archaeal genomes based on tRNA gene isotype and synteny, tRNA gene cluster content and mobilome elements. FINDINGS We demonstrated the prevalence of tRNA gene clusters in archaea. tRNA gene clus...
