| Abstract | Transposable elements (TEs) are repetitive sequences dispersed throughout mammalian genomes, and they occupy important genetic positions. TEs have been shown to have both harmful and beneficial effects such as exonization, polyadenylation, and/or altering transcription rates in various vertebrate genomes. However, to the best of our knowledge, no study has yet considered the relationship between TEs and horse genes. In this study, we examined the contribution of TEs to the horse genome by collecting TEs inserted within mRNA genes. By screening the abundance, distribution, and orientation of TEs, we found that the majority of TE insertions belong to retroelements and DNA elements, most of which exist in the coding sequences of horse genes. In addition, the MIR, L1, L2, ERVL, and ERVL-MaLR subfamilies were found to be the most abundant in both non-LTR and LTR elements. Retroelements (LTRs, LINEs, and SINEs) among the TEs inserted in the coding sequences showed a preference for antisense orientation. The most pronounced imbalance in insertional orientation was observed in LINEs, which represent 40 % of all TEs in antisense orientation. Through these analyses, we identified that a total of 1310 TEs have been integrated into horse mRNA genes and small fractions of them have been exonized into coding sequences. |

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.
