Among five hairy root lines of Picrorhiza kurrooa that were established through Agrobacterium rhizogenes, one (H7) was selected for encapsulation due to high accumulation of picrotin and picrotoxinin (8.3 and 47.6 μg/g DW, respectively). Re-grown encapsulated roots induced adventitious shoots with 73 % frequency on MS medium supplemented with 0.1 μM(More)
Aconitum violaceum Jacq. is an important medicinal species used for various health ailments including renal pain, rheumatism and high fever. In the present report, a reproducible in vitro regeneration system for Aconitum violaceum Jacq. has developed from the nodal segment of the plant. Induction of shoot buds was achieved on basal Murashige and Skoog (MS)(More)
Genetic stability and phytochemical analysis of in vitro established plants of Picrorhiza kurroa Royle ex Benth, have been carried out. Random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers were used to assess the genetic fidelity of tissue culture products including three adventitious shoots from three calli and 6 months(More)
The corresponding author withdraws/retracts this article due to the mistaken inclusion of Fig. 1b from our previously 2011 paper in Acta Physiologiae Plantarum entitled "Hairy root culture of Picrorhiza kurrooa Royle ex Benth.: a promising approach for the production of picrotin and picrotoxinin". The authors accept the mistake and thank the anonymous(More)
Picrorhiza kurrooa, one of the important plant species among the various medicinal plants, is endemic to Himalaya. As the plant is useful in the treatment of various diseases, e.g., hepatic disorders, gastric troubles, anemia, asthma, etc., illegal collection from the wild is increasing and now this plant is banned for export in any form and listed as(More)
The genus Aconitum (consists more than 250 species) is one of the most important clades of highly valued medicinal plants. Aconitum species are very essential in the traditional device of medication and feature excessive business demand in the herbal marketplace. Some of biologically energetic compounds, e.g., aconitine, indaconitine, pseudoacontine, and so(More)
A bibliometric assessment of scientific research outputs (N = 676) on Himalayan Biosphere Reserve (HBRs) with a special focus on Nanda Devi Biosphere Reserve (NDBR) during the period 1990–2010 that described the growth, contribution and impact of research was made. Research outputs for NDBR showed remarkable contribution (41.9 %) amongst HBRs and floral(More)
We studied forest vegetation at Lata–Tolma–Phagti, a protected area and part of Nanda Devi Biosphere Reserve in the western Himalaya. We analyzed community composition, population structure, regeneration patterns, and projected development of future compositional patterns. We sampled ten 10 × 10 m quadrat for tree species in each of 30 forest stands. We(More)
Significant effect of water stress conditions were observed on morphological and physiological growth parameters of tea (Camellia sinensis). Water stress tolerant tea clones suitable for hilly areas have been identified in this study. The influence of different levels of water deficit on physiological and morphological parameters in tea [Camellia sinensis(More)
OBJECTIVE To evaluate the role of magnetic resonance cholangiography (MRC) in patients with suspected choledocholithiasis. PATIENTS AND METHODS Twenty-six consecutive patients with suspected choledocholithiasis (11 men and 15 women ranging in age from 25 to 81 years) underwent three-dimensional gradient-echo MRC; each patient also underwent endoscopic(More)
