| Abstract | A method for simple and rapid detection of Ustilaginoidea virens in rice seeds was developed based on specific polymerase chain reaction (PCR). To design the specific primers for detection of U. virens, the comparison was made on 5.8S rDNA intra- and inter-specific variations in nucleotide sequences of U. virens and other pathogens: Fusarium verticillioides, Sclerotinia sclerotiorum, Tilletia barclayana, Fusarium graminearum and Magnaporthe oryzae. A 346-bp fragment could be amplified by using the specific primers uvr-F and uvr-R in U. virens, but not in other test fungi, indicating that the designed primers were specific for the detection of U. virens. U. virens was detected in nine of the 24 tested rice samples, indicating that 37.5% of the rice samples were contaminated with the false smut pathogen. The development of the simple and rapid detection technique using specific primers will be applicable for direct identification of U. virens in rice seeds to screen large numbers of samples. |

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.
