The efficacy of benzyladenine (BA) to induce multiple shoots from seed explants of chickpea (Cicer arietinum L.) was assessed. Shoot differentiation was influenced by the type of seed explant, genotype and concentration of BA. Orientation of the explant also strongly influenced the shoot regeneration response. The optimum BA concentration for shoot/shoot(More)
Wheat (Triticum aestivum L.) cv PBW 343 was grown in Hoagland solution devoid of nitrogen (–N) under two CO2 levels viz. ambient (380 μL L−1, AC) and elevated (600 ± 50 μL L−1, EC) for 20 days in growth chambers. The rate of uptake, assimilation and accumulation of nitrate was compared. At lows nitrate concentration up to 0.5 mM, rate of nitrate uptake was(More)
The effect of elevated carbon dioxide concentration on the changes in the biomass, photosynthesis and nutrient composition was investigated in two leafy vegetables. Spinach (Spinacia oleracea L.) and fenugreek (Trigonella foenum-graecum L.) plants were grown in open top chambers under either ambient (ACO2, 350 ± 50 µmol mol−1) or elevated (ECO2, 600 ± 50(More)
Shoot tip explants of 5.chickpea varieties were evaluated for efficiency of rooting using MS basal medium (1/4, 1/2 and full strength). Maximum rooting was observed in 3 varieties when cultured in MS medium with 1/4 strength. Plantlets thus developed, were further cultured in Hoagland solution (1/4 strength) for 15-20 days which enhanced root number and(More)
Granulomas develop around schistosome ova in murine Schistosoma mansoni. These granulomas have eosinophils that produce VIP. It is possible that VIP participates in immunoregulation. VIP-mediated effects usually operate through a cAMP-dependent mechanism. To identify VIP-responsive inflammatory cells in murine schistosomiasis, inflammatory cells were(More)
Chain shortening of palmitic acid was examined in vivo by comparing oxidation rates of [1-13C]palmitate vs [16-13C]palmitate fed to four male subjects consuming a high-fat diet. For 9 d subjects were fed a diet of normal foods providing an energy intake equal to their estimated requirements. The diet provided (as energy) approximately 14% protein, 46%(More)
The impact of rising atmospheric CO2 on crop productivity and quality is very important for global food and nutritional security under the changing climatic scenario. A study was conducted to investigate the effect of elevated CO2 on seed oil quality and yield in a sunflower hybrid DRSH 1 and variety DRSF 113, raised inside open top chambers and exposed to(More)
It has been found that certain antineoplastic drugs impart their function with a distinct duality. Besides being tumoricidal, they are capable of acting as immunopotentiator. This led us to investigate the effect of cytosine arabinoside (CA), vincristine sulphate (VS), cyclophosphamide (CS), mitomycin C (MMC), hydroxy urea (HU) and lipopolysaccharide (LPS)(More)
Three signalling molecules viz. salicylic acid, calcium (calcium chloride) and brassinosteroid (24-epibrassinolide) were exogenously applied at pre-anthesis stage to investigate their role in ameliorating high temperature effects on CO2 assimilation, chlorophyll fluorescence, photosynthesis pigments and their correlation with grain yield in two contrasting(More)
