| Abstract | Molecular markers associated with seedlessness in grapevine (Vitis vinifera) could be used for early trait selection in breeding programs and provide useful tools for elucidating the molecular mechanisms underlying seed abortion. In this study, the sequence fidelity of a previously reported seedlessness-linked Sequence-Characterized Amplified Region (SCAR) marker (GenBank accession #AY327513, Yang et al. in Chinese J Agri Biotech 3:13–17, 2006) was determined by comparative sequence analysis. Using available genomics resources, the SCAR marker was mapped to an overlapping region between exon-1 and intron-1 of a putative histidine triad protein (HIT) gene corresponding to an ORF of 588 bp for a peptide of 195 residues and a gene structure with 8 exons in a 14.7 kbp genomic region. However, PCR and DNA sequence analyses revealed that both seeded and seedless phenotypes of Vitis species contained highly homologous sequences in an EcoRI-delimited region of up to 5 kbp surrounding the SCAR marker. The absence of linkage between the marker and the seedlessness trait does not support a role for the HIT gene in seedlessness development, or the potential for the use of this SCAR marker in the identification/selection of seedless progeny. |

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.
