| Abstract | Ty1/copia and Ty3/gypsy LTR retrotransposons represent a significant part of plant genomes and play an important role in their structure, functioning, and evolution. The majority of information about this group of transposable elements is related to agricultural plant species and model objects, such as Arabidopsis thaliana. The most investigated groups of LTR retrotransposons are those present in angiosperms, including the Ty1/copia (Sire, Oryco, Retrofit, and Tork families) and Ty3/gypsy (CRM, Galadriel, Reina, Del, REM, Athila, and Tat) superfamilies. The genomes of gymnosperms can include both common (CRM, Galadriel, Reina, and Del), and specific Ty3/gypsy (PpRT1, IFG7, PtGypsyX1, PGGYPSYX1) and Ty1/copia (TPE1, Tpa, PtCopiaX1, PGCOPIAX1, and Tgb) LTR retrotransposons. There is little information about the diversity and distribution of LTR retrotransposons in nonseed plants (mosses, ferns, etc.). Fern genomes contain some Ty3/gypsy retroelements, closely related to the CRM family, as well as some specific retroelements from the Galahad and Mordred families. Club-moss genomes contain Ty3/gypsy elements from the Tcn1 family, originally described only in fungal genomes, and from the Galahad and Mordred families. Retroelements, described in moss genomes, belong to the Galahad and Tcn1 families. Ty1/copia retroelements have been revealed in the genomes of certain nonseed plants, but they have not been described in detail, and the question of their belonging to any phylogenetic group of LTR retrotransposons still remains unclear. There are no data on the diversity of LTR retrotransposons in the genomes of green algae and charophytes, except for information about the REM (Ty3/gypsy) element from the genome of green alga Chlamydomonas reinhardtii and the Osser (Ty1/copia) element from the genome of colonial green alga Volvox carteri. |

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.
