| Abstract | Inter simple sequence repeat (ISSR) polymorphism was used to determine genetic diversity and phylogenetic relationships in Oryza. Forty two genotypes including 17 wild species, representing AA,BB,CC,EE,FF,GG,BBCC,CCDD, and HHJJgenomes, two cultivated species, Oryza sativa (AA) and Oryza glaberrima (AA), and three related genera, Porteresia coarctata, Leersia and Rhynchoryza subulata, were used in ISSR analysis. A total of 30 ISSR primers were screened representing di-, tri-, tetra- and penta-nucleotide repeats, of which 11 polymorphic and informative patterns were selected to determine the genetic diversity. The consensus tree constructed using binary data from banding patterns generated by ISSR-PCR clustered 42 genotypes according to their respective genomes. ISSR analysis suggests that the genus Oryza may have evolved following a polyphyletic pathway; Oryza brachyantha (FF genome) is the most divergent species in Oryza and Oryza australiensis (EE genome) does not fall under the Officinalis complex. DNA profiles based on ISSR markers have revealed potential diagnostic fingerprints for various species and genomes, and also for individual accessions/cultivars. Additionally ISSR revealed 87 putative genome/species-specific molecular markers for eight of the nine genomes of Oryza. The ISSR markers are thus useful in the fingerprinting of cultivated and wild species germplasm, and in understanding the evolutionary relationships of Oryza. |

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.
