| Abstract | Map-based cloning of mutant genes is straightforward if the genome sequence and sufficient molecular markers are available. When a mutated gene in Arabidopsis causes a clear phenotype and is located in a genomic region where sufficient meiotic recombination takes place, the gene can be identified within 6–12 months. However, mutated genes that cause weak phenotypes are difficult to map to small genomic intervals due to faulty selection of F2 plants. Here, we describe a method that allows for rapid identification of roughly mapped genes by using a massive parallel sequencing strategy. A genomic region of 150 kb was PCR amplified in 7–17 kb pieces from an EMS Arabidopsis onset of leaf death (old) mutant and its wild-type accession Landsberg erecta (Ler-0). Massive parallel sequencing and subsequent de novo assembly of the short sequences reliably identified 253 polymorphisms in a 110-kb region between the reference Col-0 and Ler-0 sequence. The analysis further revealed potential mutations in the old mutant of which one was confirmed to be present in the mutant. Thus the described method can be used for accelerating the map-based cloning of genes that cause weak phenotypes. An accompanying advantage is that the amplified fragments can be cloned and used to complement the mutant. |

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.
