520 |a According to current textbooks, the principal task of transfer and ribosomal RNAs (tRNAs and rRNAs, respectively) is synthesizing proteins. During the last decade, additional cellular roles for precisely processed tRNA and rRNAs fragments have become evident in all kingdoms of life. These RNA fragments were originally overlooked in transcriptome datasets or regarded as unspecific degradation products. Upon closer inspection, they were found to engage in a variety of cellular processes, in particular the modulation of translation and the regulation of gene expression by sequence complementarity- and Argonaute protein-dependent gene silencing. More recently, the presence of tRNA and rRNA fragments has also been recognized in the context of plant-microbe interactions, both on the plant and the microbial side. While most of these fragments are likely to affect endogenous processes, there is increasing evidence for their transfer across kingdoms in the course of such interactions; these processes may involve mutual exchange in association with extracellular vesicles. Here, we summarize the state-of-the-art understanding of tRNA and rRNA fragment's roles in the context of plant-microbe interactions, their potential biogenesis, presumed delivery routes, and presumptive modes of action
