| Abstract | A known arabidopsis cDNA clone, the CRT/DRE binding factor 1 (CBF1), was isolated and introduced into tobacco plants. It has been reported that CBF1 is one member of CBF gene family related to low temperature and enhancing low temperature tolerance of plants. In the present work, the transcripts could be detected in the transgenic lines. The photochemical efficiency of PSII (F(v)/F(m)) and the photo-oxidizable P700 in the transgenic lines overexpressing CBF1 were higher than that in the wild type plants during the chilling stress under low irradiance. Similarly, the higher NPQ, higher qf, lower Phi(NF), higher activity of SOD, and lower content of MDA were also detected in the transgenic tobacco lines. Additionally, higher expression levels of Nicotiana tabacum copper/zinc superoxide dismutase (Cu/Zn SOD) were also detected in the transgenic lines. These results suggest that CBF1 protein plays an important role in protection of PSII and PSI during the chilling stress under low irradiance. |

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.
