Mycobacterium genus and tRNA arrays.

Mycobacterium genus and tRNA arrays. Mem Inst Oswaldo Cruz. 2019;114:e180443 Authors: Morgado SM, Vicente ACP Abstract The presence of tRNA array, a region with high tRNA gene number and density, has been demonstrated in Mycobacterium genus. However, a recent phylogenomic study revealed the existence of five distinct monophyletic groups (genera) within this genus. Considering this new scenario, and based on in-silico analyses, we have identified and characterised the abundance and diversity of tRNA array units within Mycobacterium, Mycolicibacterium gen. nov., Mycolicibacillus gen. nov., and Mycobacteroides gen. nov. The occurrence and prevalence of tRNA arrays among the genera belonging to Actinobacteria indicate their possible role in the organismal fitness. PMID: 31090860 [PubMed - in process]
