| Abstract | As a high stress resistance psammophyte with the characteristic of sand fixation and winterfat, Ceratoides lanata had been successfully introduced into many countries in recent years. The leaves and twigs of Ceratoides lanata in room temperature were used as the Driver and those treated by cold stress were used as Tester. Tester and Driver ds cDNA were prepared from their high quality mRNA which were purified from their total RNA. Tester and Driver cDNA were separately digested to obtain shorter, blunt-ended molecules by RasI. Then two Tester populations are created with different adaptors, while Driver cDNA has no adaptors. Differentially expressed genes were equalized and enriched by two round subtractive hybridizations using excess Driver population as compared with Tester population. The differentially expressed cDNAs were exponentially amplified by first round suppression PCR using the diluted hybridization product as template, and then the secondary PCR was performed using the first PCR product as template by nested primers to finally enrich the differentially expressed cDNAs, which consists of the SSH library of Ceratoides lanata. These cDNAs were inserted into vectors and 362 cDNA clones were obtained. The sequencing results showed that some cDNAs of cold-stressed Ceratoides lanata SSH library have relatively high homology with known stress resistance-related genes or proteins, and other cDNAs are new genes which are firstly reported here. Our result lays a foundation for the cDNA cloning of valuable genes including antifreeze genes, heat-resistant genes, drought-tolerant genes, alkali-salt-tolerant genes from Ceratoides lanata, and their transgenic application |

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.
