| Abstract | The study was focused on fatty acid (FA) composition of lipids from the seedlings and roots of crops having different cold resistance and grown at 27°C or 4°C. Biosynthesis of FA in the lipids of seedlings and roots of cold-susceptible maize (Zea mays L.) at both growth temperatures was controlled by chloroplast ω6 desaturase and microsomal ω6 desaturase, respectively. The content of linoleic acid was 56.2% and 43.3% in the coleoptiles of maize seedlings grown at 4 and 27°C, respectively, and in the roots it was 52.2% and 38.5%, respectively. The content of α-linolenoic acid in the coleoptiles was 6.7–6.8% at both temperatures, while in the root lipids it was higher at low temperature (3.15% at 27°C vs. 4.7% at 4°C). FA biosynthesis in the seedling coleoptiles of wheat (Triticum aestivum L.) and Siberian wild rye (Elymus sibiricus L.) grown at low temperature was controlled by the chloroplast ω3 desaturase. A minor increase in the content of α-linolenoic acid was observed at low temperature: 29.7% to 30.2% in wheat and 22.8% to 25.8% in wild rye. In the root tissues of these species, the biosynthesis of α-linolenoic acid was controlled by the microsomal ω3 desaturase. The content of α-linolenoic acid was higher at low temperature: in wheat it was 6.1% at 27°C and 17.1%, and 4°C, while in Siberian wild rye, 7.1% and 12.0% at 4 and 27°C, respectively. |

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.
