| Abstract | T0135 is a variant selected from the progeny of a rice line telotrisomic for the short arm of chromosome 11 (2n+11S·). Fluorescent in situ hybridization (FISH) results indicated that T0135 contained two telocentric chromosomes, which have two centromere-specific molecular markers (5S rDNA) for chromosome 11; thus T0135 is a newly-described rice chromosome variant with two dicentric chromosomes, named 22+11L·+11L·+11S·11S·+11S·11S· (22 represents the 22 chromosomes excluding chromosome 11 in the rice genome, “·” represents the centromere). To investigate the genetic stability of the rice dicentric chromosomes during sexual reproduction, we observed the chromosome types in the progeny. Ninety-four percent of the progeny had the same chromosome type as the parental line. This result indicates that the dicentric chromosomes are mostly stable during mitosis and meiosis. Immunofluorescence analysis for centromere specific histone H3 (CENH3) revealed that only one centromere is active and the other centromere is inactivated in the rice dicentric chromosomes. |

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.
