| Abstract | The genetic classification for the N-genome chromosomes has been developed on the basis of C-banding analysis on the set of Triticum aestivum × Aegilops uniaristata single chromosome addition lines and examination of A. uniaristata ( $$ {\text{2n = 2}} \times { = 14} $$ , NN), Aegilops ventricosa ( $$ {\text{2n = 4}} \times { = 28} $$ , DDNN) and Aegilops recta ( $$ {\text{2n = 6}} \times { = 42} $$ , UUXnXnNN) accessions carrying intergenomic translocations using fluorescence in situ hybridisation with probes for three repetitive DNA sequences as well as the 5S and 45S rDNA families. The N-genome chromosomes of the tetraploid A. ventricosa show significant changes relative to the diploid progenitor species, while those of the hexaploid A. recta are similar to A. uniaristata with regard to the distribution of C-bands, 45S and 5S rDNA loci and hybridisation sites of all the three families of tandem repeats. The possible mechanisms of N-genome evolution are discussed. |

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.
