| Abstract | A pair of novel high-molecular-weight glutenin subunits (HMW-GS) 1Dx3.1t and 1Dy11*t were revealed and characterized from Aegilops tauschii Coss. subspecies tauschii accession AS60. SDS-PAGE band of 1Dx3.1t was between those of 1Dx2 and 1Dx3, while 1Dy11*t was between 1Dy11 and 1Dy12. The lengths of 1Dx3.1 t and 1Dy11* t were 2,514 bp and 1,968 bp, encoding 836 and 654 amino acid residues, respectively. Their authenticity was confirmed by successful expression of the coding regions in Escherichia coli. Network analysis indicated that 1Dx3.1 t together with other five rare alleles only detected in Asia common wheat populations represented the ancestral sequences in Glu-D1 locus. Neighbor-joining tree analysis of previously cloned x-type and y-type alleles in the Glu-D1 locus supported the hypothesis that more than one Ae. tauschii genotypes were involved in the origin of hexaploid wheat and that different Ae. tauschii accessions contributed the D genome to common wheat and Ae. cylindrical Host, respectively. An Ae. tauschii accession with 1Dx3.1 t or a closely related allele probably have involved in the origin of common wheat. Since accession AS60 used in this study belonged to typical ssp. tauschii, present results suggested the possibility that ssp. tauschii was involved in the evolution of common wheat. |

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.
