| Abstract | Ribgrass mosaic virus (RMV), turnip vein-clearing virus (TVCV) and Youcai mosaic virus (YoMV; formerly designated as oilseed rape mosaic virus; ORMV) belong to the genus Tobamovirus and are arranged in one out of three subgroups because of their common host range, serological cross-reactivity and amino acid composition of their coat proteins. The recently defined species Wasabi mottle virus (WMoV) is closely related to the same subgroup. The distinction of the four species is difficult and the lack of sequence information of a wide range of isolates has led to an unclear nomenclature. To clarify this situation we sequenced the coat protein genes from 18 isolates which were serologically related to members of the species of this cluster. The size of the coat protein was conserved with the exception of one isolate which revealed an N-terminal extension due to the mutation of three stop-codons. Phylogenetic analysis of these CP ORFs resulted in a tree with three clusters each containing at least one of the approved species RMV, TVCV and 1ptYoMV/WMoV in which our isolates were distributed. The tree was congruent and did support the present taxonomic status of species within this subgroup.For practical purpose we developed a subgroup 3 specific primer pair and a species differentiating restriction fragment length polymorphism (RFLP). Sequencing of the genome of Streptocarpus flower break virus (SFBV) which is serologically distantly related to the subgroup 3 viruses revealed a distinct genome organization. Therefore we propose that this virus should be regarded as a member of a species not belonging to any of the subgroups so far established. |

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.
