| Abstract | In the rice genome, insertions and eliminations of transposable elements have generated numerous transposon insertion polymorphisms (TIPs). Common wild rice (O. rufipogon Griff.), the ancestor of Asian cultivated rice (O. sativa L.), carries abundant genetic variations. To find subspecies-specific (SS) markers that can distinguish O. sativa ssp. indica and ssp. japonica, some long terminal repeat (LTR) sequences (sc1-14) of AA genome-specific RIRE retrotransposon were isolated from O. rufipogon genome. Sequences sc1 and sc12 were successfully utilized to develop the SS marker system based on retrotransposon inserted position polymorphisms. Twenty-two SS markers (ssi1-9, ssj1-13) were developed, where ssi1-9 are the indica-specific types, and ssj1-13 the japonica-specific types. The average accuracy of these markers in distinguishing the two subspecies is over 85%. SS marker ssj-10 can distinguish the two subspecies at 100% accuracy. Principal component analysis (PCA) showed that these markers could successfully distinguish indica from japonica varieties, regardless of their geographical origin. |

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.
