Abstract: The present invention provides a superoxide dismutase gene from Potentilla atrosanguinea, a construct containing the gene coding for superoxide dismutase and transformed E.coli producing the SOD protein.

Abstract: The present invention relates to three novel genes of SEQ ID Nos. 1-3 useful for water-stress tolerance in biological systems, wherein said genes are differentially expressed in Tea plant under drought conditions and a method of introducing said genes into a biological system to help develop water stress tolerance.

Abstract: The present invention relates to cloning of novel gene sequences expressed and repressed during winter dormancy in the apical buds of Camellia sinesis L. (O.) Kuntze (hereinafter, referred to tea) bush, particularly, relates to identification, cloning and analysis of novel 3 prime (hereinafter called as 3?) ends of the genes (gene in the present invention refers to the deoxyribonucleic acid (hereinafter known as, DNA) sequences that are expressed and repressed in winter-dormant apical buds of tea. 3? end refers to that end of DNA which has free hydroxyl group at 3rd position of the carbohydrate moiety of the DNA molecule.

Abstract: This invention relates essential oil constituents citronellol and rose oxides and other constituents from a cold desert plant i.e. Dracocephalum heterophyllum benth, the present invention also provides a process for the extraction of the essential oil.

Abstract: A process for the production of steviosides from Stevia rebaudiana Bertoni includes extraction of comminuted plant material by directly injecting steam into the extractor followed by filtration to get aqueous extract and alkali treatment to remove unwanted compounds in the form of precipitate. The treated aqueous extracted was filtered and the filtrate was first treated with gel or macroporous strong acid cation exchange resin and then with gel or macroporous weak base anion exchange resin. The aqueous eluant containing steviosides was concentrated to obtain purified steviosides.

Abstract: An isolated DNA sequence set forth in SEQ ID NO: 32, which is differentially expressed in apical buds of plant Caragana jubata (Pall.) under freezing conditions, is disclosed.

Abstract: This invention relates to a simple, convenient, portable mini-distillation apparatus for the production of essential oils and hydrosols, said apparatus is useful to distill essential oils and hydrosols such as rose water, ajowain water from fresh and dried plant material like leaves, flowers, roots and rhizomes by water distillation, water and steam distillations and as an optional, steam distillation can also be performed at atmospheric pressure as well as slightly higher and lower than atmospheric pressure, said apparatus can be heated on brick-clay furnace with small agro-waste, LPG cooking gas, electrically heated stove or kerosene/diesel burner etc. and requires minimum attention during handling; since the apparatus is made of stainless steel and glass, the essential oil distilled is of better quality.
