<p>Since their first discovery in the early 60’s, research on tRNAs has always been interconnected with the evolution of the genetic code and translation. Today, more than ever, it is evident that tRNA research continues to reveal new and surprising aspects of cellular metabolism. Research on the role of tRNAs as unique adaptor molecules has revolutionized synthetic biology. Moreover, new information emerge from studies on tRNA biogenesis, processing, editing, transfer and localization, the recognition of tRNA by aminoacyl-tRNA synthetases and their role in many diseases, the relationship between structure and function of translation factors, the regulation of translation at many levels, the role of many tRNA-related proteins or protein networks outside translation and finally, the regulatory role of tRNA itself and its fragments (tRFs), post-transcriptionally. Finally, the tRNA-dependent gene expression regulation in many pathogens, via the T-box riboswitches, bring into the spotlight novel molecular targets for the development of new antibiotics.<br></p>
