The RNA degradome: a precious resource for deciphering RNA processing and regulation codes in plants.

ABSTRACT: The plant RNA degradome was defined as an aggregate of the RNA fragments degraded from various biochemical pathways, such as RNA turnover, maturation and quality surveillance. In recent years, the degradome sequencing (degradome-seq) libraries became a rich storehouse for researchers to study on RNA processing and regulation. Here, we provided a brief overview of the uses of degradome-seq data in plant RNA biology, especially on non-coding RNA processing and small RNA-guided target cleavages. Some novel applications in RNA research area, such as in vivo mapping of the endoribonucleolytic cleavage sites, identification of conserved motifs at the 5' ends of the uncapped RNA fragments, and searching for the protein-binding regions on the transcripts, were also mentioned. More importantly, we proposed a model for the biologists to deduce the contributions of transcriptional and/or post-transcriptional regulation to gene differential expression based on degradome-seq data. Finally, we hope that the degradome-based analytical methods could be widely applied for the studies on RNA biology in eukaryotes.
