| Abstract | The effects of salt stress on the activity of antioxidant enzymes in oilseed rape seedlings (Brassica napus L.) were studied. The results showed that the relative water content in leaves of oilseed rape seedlings was gradually decreased and the electrical conductivity was increased after 24 h under 0, 100, 150, 200, 250 and 300 mmol L−1 NaCl. The activity of peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT) was gradually increased under salt stress. After 24 h, the activity of POD and SOD was both maximal under 200 mmol L−1, but that of CAT was maximal under 150 mmol L−1. Subsequently, the activity of these antioxidant enzymes was all decreased. Quantitative real-time PCR analysis revealed that they were salt-inducible genes and their transcript levels were gradually increased with the increase of salt concentration. As the same as the change of POD and SOD activity, the transcript levels of POD and SOD was most abundant after 24 h treatment with 200 mmol L−1 sodium chloride, but that of CAT was most abundant under 150 mmol L−1. Therefore, these results from above indicated that the expression of POD, SOD and CAT genes was induced by salt (such as NaCl) and their activities were positively correlated with expression of their genes. |

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.
