| Abstract | The presence and function of several proteins secreted into floral nectars has been described in recent years. Here we report the presence of at least eight distinct proteins secreted into the floral nectar of the tropical tree Jacaranda mimosifolia (Bignoniaceae). Steps were initiated to identify and characterize these proteins in order to determine potential functions. The N-terminal sequence of the major Jacaranda nectar protein, JNP1, at 43 kDa contained similarity with members of the plant GDSL lipase/esterase gene family. Based upon this sequence, a full-length cDNA was isolated and predicted to encode a mature protein of 339 amino acids with a molecular mass of 37 kDa. Both raw nectar and heterologously expressed JNP1 displayed lipase/esterase activities. Interestingly, J. mimosifolia flowers produce an opaque, white colored nectar containing spherical, lipophilic particles approximately 5 μm in diameter and smaller. GS-MS analysis also identified the accumulation of free fatty acids within the nectar. It is proposed that JNP1 hydrolyzes Jacaranda nectar lipids with the concomitant release of free fatty acids. Potential functions of JNP1 in relation to pollinator attraction and prevention of microbial growth within nectar are briefly discussed. |

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.
