| Abstract | Initially regarded as mere intermediates between coding DNA sequences and proteins, RNAs have been ascribed a plethora of novel roles in the past decades. Today, they are recognized as active regulatory molecules, influencing processes such as gene expression, chromatin organization or genome stability that affect all aspects of a plant’s life. This Research Topic aims at highlighting the broad biological significance of RNAs in plant systems and contains eight original research articles, one review and four mini-reviews, covering various RNA-based mechanisms in higher plants. As they are being synthesized, RNAs fold into secondary structures, which can influence RNA metabolism at multiple levels, including transcript processing and stability, or protein translation. Yang et al. not only bring attention to the significance of RNA structures, but also summarize the currently available methods to study the folding of specific RNA molecules or profile genome-scale RNA structuromes.After transcription, RNAs require proper maturation through a multi-step process integrating capping, splicing and polyadenylation. Pieczynski et al. describe the importance of accurate splicing of the precursor mRNA (pre-mRNA) encoding the small subunit of the Arabidopsis nuclear cap-binding complex, CBP20, which contains seven introns. Of these, intron 4 belongs to the U12 class of introns and separates the gene into an N-terminal half encoding the RNA-binding moiety and a C-terminal half encoding... |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
