| Abstract | Shampoo ginger (Zingiber zerumbet Smith) has a high content and large variety of terpenoids in the essential oil of its rhizome. Here, we report on the isolation of a cDNA clone (ZSS1) encoding α-humulene synthase, a possible key enzyme of zerumbone biosynthesis. This clone contains an open reading frame of 1,644 bp and is predicted to encode a protein of 548 amino acids with a calculated molecular mass of 64.5 kDa. The deduced amino acid sequence shows 34–63% identity with known sesquiterpene synthases of other angiosperm species. Based on exon-intron organization, ZSS1 is classified as the terpene synthase-III (TPS-III) subfamily. When expressed in Escherichia coli, the recombinant enzyme catalyzed the formation of a major product, α-humulene (95%) and a minor by-product, β-caryophyllene (5%). Introduction of ZSS1 and the foreign mevalonate pathway involved in FPP synthesis into E. coli results in in vivo production of α-humulene. Transcript of ZSS1 was detected almost exclusively in rhizomes and was up-regulated in both leaves and rhizomes after treatment with methyl jasmonate (MeJA), suggesting its ecological function in shampoo ginger. |

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.
