Abstract:

RNAs fold into complex secondary and tertiary structures via hydrogen bond pairing to enable their diverse functions in cells after dynamic changes according to environment. RNA structure is considered to be related to the regulation of gene expression and ligand sensing in plants, and is also considered to be an important factor in post-transcriptional regulation. Structured RNA can also affect the dimensional structure of RNA binding proteins and their functions. Thus, the analysis of RNA structure is particularly critical in the study of RNA function. At present, various detection methods for RNA secondary structure(RSS)has been developed from X-ray to enzyme digestion and chemical probe labeling, which can be combined with high-throughput sequencing to construct models. In addition, machine learning and other methods also provide new ideas for the detection of RNA structure. In this review, we summarize the factors affecting the RNA structure in vivo and recent reported methods for probing RNA structure in vivo, discuss the significances of developing novel prediction methods for RSS under the limitations of current methods as well as the issues, and prospect the future development trend of computer prediction methods and experimental methods, aiming to provide a methodological reference for subsequent research on RNA structure.
