RNA biology of symbiotic bacteria in insects
 MACHOVÁ, Kamila
Non-coding RNAs (ncRNAs) represent an important part of bacterial genomes. However, only few studies RNAs with limited sampling were done concerning ncRNAs of insect endosymbiontic bacteria. This study provides a broad in silico genome sampling of insect endosymbionts (63 lineages of 27 genera) for ncRNAs and their modifications. Most strikingly it was found out that i) genes encoding modification enzymes conserved in particular genomes differ to high extent, ii) most of tRNA and rRNA modifications sites are conserved regardless whether the gene encoding the corresponding modification enzyme is conserved, iii) multiple endosymbiont lineages do not encode a full set of tRNAs. Our data imply that translation of endosymbionts is much less efficient compared to phylogenetically related free-living bacteria and that some of symbionts possibly need to cooperate with their cosymbionts or maybe even with their host to maintain translation.
