Abstract:
Processing of mature transfer RNAs (tRNAs) produces complex populations of tRNA-derived fragments (tRFs). Emerging evidence shows that tRFs have important functions in bacteria, animals, and plants. Here, we review recent advances in understanding plant tRFs, focusing on their biological and cellular functions, such as regulating stress responses, mediating plant-pathogen interactions, and modulating post-transcriptional gene silencing and translation. We also review sequencing strategies and bioinformatics resources for studying tRFs in plants. Finally, we discuss future directions for plant tRF research, which will expand our knowledge of plant non-coding RNAs.

Transfer RNA Synthesis
Each of these chemical modifications is carried by a specific enzyme, post-transcription. All of these enzymes have unique base and site-specificity. Methylation, the most common chemical modification, is carried by at least nine different enzymes, with...

Nucleic Acids
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

RNA Interference
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
