| Abstract | The blt4 barley gene family encodes non-specific lipid transfer proteins and has been shown, by in situ localisation, to be expressed in the epidermal cells of leaves. The transcriptionally controlled, low-temperature-responsive member of this gene family, blt4.9, is predominantly expressed in shoot meristems. The promoter region (1938 bp) of blt4.9 contains sequence motifs which have been implicated in responses to low temperature, abscisic acid and other environmental factors. Deletion analysis showed that a 42 bp sequence proximal to, but not including, the CAAT and TATA boxes, confers enhanced low-temperature response to a reporter gene in a barley shoot explant transient expression system. Other promoter regions were shown to contain negative and positive regulatory regions. Electrophoretic mobility shift analysis (EMSA) was used with nuclear proteins from either low-temperature- or control-temperature-treated plants to further investigate the blt4.9 promoter. Synthetic oligonucleotides were used to identify a hexanucleotide, CCGAAA, within the 42 bp, low-temperature-responsive promoter region, as the binding site of a low-mobility nuclear protein complex. This complex was present in nuclear extracts from both low-temperature-treated and control plants and was the only complex formed within this region. Mutation of the CCGAAA motif within the low-temperature-responsive 42 bp promoter sequence reduced low-temperature responsiveness to basal levels. A related upstream element, CCGAC, known to be a low-temperature-responsive element in other plants, did not bind to nuclear proteins in this study. It is proposed that the hexanucleotide CCGAAA, at -195 from the first ATG, is involved in the low-temperature response of blt4.9 in barley. |

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.
