| Abstract | A naturally occurring 1.1 kb RNA was isolated from purified virions of bamboo mosaic potexvirus isolate S (BaMV-S). This RNA is a defective RNA (D RNA) derived from a single internal deletion of the BaMV genome. A cDNA clone representing the complete nucleotide sequence of the BaMV-S D RNA was generated and its nucleotide sequence was determined. The BaMV D cDNA is 1015 nts in length [excluding the poly(A) tail] and consists of two regions corresponding to 867 nts of the 5′ terminus and 148 nts of the 3′ terminus of the BaMV genomic RNA. BaMV D cDNA contains a single open reading frame (ORF) encoding a putative 29.7 kDa protein comprised of a fusion of the first 258 amino acids of BaMV ORF 1 and the last 2 amino acids of coat protein. The coding capacity of D RNA was verified by in vitro translation of native BaMV-S D RNA and of 1.1 kb RNA transcribed in vitro from the full-length D cDNA. BaMV D RNA can be reproducibly generated by serial passages of BaMV-S in Nicotiana benthamiana and is the first D RNA in the potexvirus group shown to be generated de novo. Alignments of sequences surrounding the 5′ and 3′ junction borders of reported potexvirus D RNAs reveal a 65.2–84.6% sequence identity, suggesting that common mechanisms for viral RNA recombination are involved in the generation of potexvirus D RNAs. |

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.
