| Abstract | KEY MESSAGE: Trimeric Galanthus nivalis agglutinin-related lectin of Orchidaceae with two conformational forms was first studied in Dendrobium pendulum . It was highly expressed by stress factors. Using mannan-agarose column chromatography, a mannose-binding protein was purified from Dendrobium pendulum Roxb. pseudobulb. After heating in the presence of sodium dodecyl sulfate (SDS) with or without 2-mercaptoethanol, the protein showed one band with molecular mass of 14.0 kDa on SDS-polyacrylamide gel electrophoresis (PAGE). Without heating, three bands were found at positions of 14.0, 39.4, and 41.5 kDa, but a higher amount of 39.4 and 41.5 kDa protein bands were seen in the presence of 2-mercaptoethanol. Liquid chromatography-tandem mass spectrometry and database search indicated that the 14.0 kDa protein band contained three peptide fragments identical to parts of a lectin precursor from Dendrobiu m findleyanum Parish & Rchb.f. Native-PAGE and Ferguson plot showed that the purified protein had two native forms with molecular masses of 44.2 and 45.3 kDa, indicating three 14.0 kDa polypeptide subunits. The purified protein exhibited the agglutination activity with trypsinized chicken erythrocytes. It was then recognized as a Galanthus nivalis agglutinin-related lectin and named D. pendulum agglutinin (DPA). Using reverse transcription-polymerase chain reaction and DNA sequencing, the deduced amino acid sequence of DPA precursor showed the highest homology (96.4%) with a lectin precursor of D. findleyanum and contained three mannose-binding sites. Greater amounts of DPA were found when the pseudobulbs were treated with stress factors including ultraviolet light, abscisic acid, hydrogen peroxide, and acetylene gas. |

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.
