(ELSEVIER, 2003-09)An efficient and reproducible protocol for Agrobacterium-mediated plant transformation has been standardized in Indian spinach (Beta palonga) with a standard vector (pCambia 1304). Passage wise subculture in medium containing ... -
Airborne rice pollen and pollen allergen in an agricultural field: aerobiological and immunochemical evidence
(ROYAL SOC CHEMISTRY, 2003-12)Grass pollens are well known among the health hazardous bioaerosols causing respiratory allergy. Being an important member of the grass family, the rice plants contribute a huge pollen load in agricultural fields during ... -
Luffa sponge - a unique matrix for tissue culture of Philodendron
(CURRENT SCIENCE ASSN, 2004-01-25)An efficient and simple micropropagation protocol of Philodendron 'Xanadu', highly esteemed for its beautiful foliage, has been established. Rapid multiplication was attained by high concentration of N-6-benzyladenine, but ... -
Volumetric assessment of airborne fungi in two sections of a rural indoor dairy cattle shed
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-02)There is increasing concern about the exposure to fungal aerosols in occupational environments and associated respiratory allergic diseases and asthma. A large number of people work in cattle sheds around the world, pulmonary ... -
Identification of shared allergenic components from four common and dominant pollen taxa of Arecaceae
(CURRENT SCIENCE ASSN, 2004-06-10)The Arecaceae (palm) family is predominantly distributed in the tropics and subtropics. Areca catechu (betel nut), Borassus flabellifer (fan palm), Cocos nucifera (coconut) and Phoenix sylvestris (date sugar palm) are ... -
Air-borne viable, non-viable, and allergenic fungi in a rural agricultural area of India: a 2-year study at five outdoor sampling stations
(ELSEVIER SCIENCE BV, 2004-06-29)The information on airborne allergenic fungal flora in rural agricultural areas is largely lacking. Adequate information is not available to the bioaerosol researchers regarding the choice of single versus multiple sampling ... -
Molecular profiling and development of DNA marker associated with drought tolerance in tea clones growing in Darjeeling
(CURRENT SCIENCE ASSN, 2004-07-10)Amplified Fragment Length Polymorphism (AFLP) fingerprints were developed for 29 Darjeeling-grown tea clones. AFLP diversity estimates based on Jaccard's coefficient allowed separation of the 29 clones into three clusters. ... -
The mannitol cycle in Pleurotus ostreatus (Florida)
(ELSEVIER SCIENCE BV, 2004-07-15)In mushroom, presence of the mannitol cycle has not been reported so far although the polyol is supposed to be generated by the reduction of fructose by mannitol dehydrogenase. This study submits evidence for the presence ... -
