Cyto-palynological, Biochemical and Molecular Characterization of Original and Induced Mutants of Garden Chrysanthemum
(Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, 2009)A large number of new somatic flower color/type mutants have been evolved by induced mutations in different ornamental plants. Few reports are available on the systematic work being done on the comparative analysis of ... -
Web 2.0 and Social Web Approaches to Digital Libraries
(IGI GLOBAL, 2010)The Chapter begins with a definition of digital library approaches and features, examines ways in which open source and social software applications can serve to fill digital library roles. In order to incorporate Web 2.0 ... -
Current outlooks on the lipids of gastric membranes and beyond
(Research Trends, 2008)It has become increasingly clear in the recent years that the phospholipids and cholesterol are more functionally alive as the main building blocks of the bio-membranes than we previously thought. By virtue of its ability ... -
Regulation of tyrosine kinase activity during capacitation in goat sperm
(SPRINGER, 2010-03)Protein tyrosine phosphorylation is a key event accompanying sperm capacitation. Although this signaling cascade generates an array of tyrosine-phosphorylated polypeptides, their molecular characterization is still limited. ... -
Dielectric relaxation in In(Mg 0.5Ti 0.5)O 3 nanoceramic
(Elsevier B.V., 2009)The complex perovskite oxide indium magnesium titanate, In(Mg 1/2Ti 1/2)O 3 (IMT) is synthesized by a solid stale reaction technique. Impedance spectroscopy is applied to investigate the electrical properties of IMT in a ... -
Entanglement in a molecular three-qubit system
(IOP PUBLISHING LTD, 2010-01-13)We study the entanglement properties of a molecular three-qubit system described by the Heisenberg spin Hamiltonian with anisotropic exchange interactions and including an external magnetic field. The system exhibits ... -
Mutation in the lysA gene impairs the symbiotic properties of Mesorhizobium ciceri
(SPRINGER, 2010-01)A Tn5-induced mutant of Mesorhizobium ciceri, TL28, requiring the amino acid lysine for growth on minimal medium was isolated and characterized. The Tn5 insertion in the mutant strain TL28 was located on a 6.8-kb EcoRI ... -
Oxidative stress and antioxidant activity as the basis of senescence in Hemerocallis (day lily) flowers
(Academic Journals, 2009-09)Senescence can be viewed as a developmental change that leads to the death of plant tissues. Naturally senescence is generally accepted as being genetically programmed. Petals are the floral organs which primarily determine ... -
Management of chimera and in vitro mutagenesis for development of new flower color/shape and chlorophyll variegated mutants in chrysanthemum.
(2008)Mutation breeding is an established method for crop improvement and has played a major role in the development of many new flower color/shape mutant varieties in ornamentals. The main bottleneck with vegetatively propagated ... -
A study of the gamma-ray flux during the total solar eclipse of 1 August 2008 at Novosibirsk, Russia
(ELSEVIER SCIENCE BV, 2010-01-01)In the past, there have been reports of the observation of decrease in the flux of secondary cosmic gamma-rays during a total solar eclipse. We have measured the flux of secondary cosmic gamma-rays during the total solar ... -
Differential antioxidative responses of indica rice cultivars to drought stress
(SPRINGER, 2010-01)The present study investigated the linkages between drought stress, oxidative damages and variations in antioxidants in the three rice varieties IR-29 (salt-sensitive), Pokkali (salt-tolerant) and aromatic Pusa Basmati ... -
Intergeneric protoplast fusion between Calocybe indica (milky mushroom) and Pleurotus florida aids in the qualitative and quantitative improvement of sporophore of the milky mushroom
(SPRINGER, 2010-02)This article primarily focuses on the production of somatic hybrid sporophores through PEG-mediated protoplast fusion between Calocybe indica var. APK2 and Pleurotus florida. To screen the hybrid strains a selection strategy ... -
A Molecular Insight into the Early Events of Chickpea (Cicer arietinum) and Fusarium oxysporum f. sp ciceri (Race 1) Interaction Through cDNA-AFLP Analysis
(AMER PHYTOPATHOLOGICAL SOC, 2009-11)Wilt of chickpea caused by Fusarium oxysporum f. sp. ciceris is one of the most severe diseases of chickpea throughout the world. Variability of pathotypes of F. oxysporum f. sp. ciceris and breakdown of natural resistance ... -
Determination of the depth of an etch pit through studies of diffraction rings
(PERGAMON-ELSEVIER SCIENCE LTD, 2009-04-01)A Solid State Nuclear Track Detector (SSNTD) can be used to identify an impinging ion as well as to determine the energy of that ion. The track of the ion is made visible by chemically 'etching' the detector after exposure. ... -
Tissue specific expression of potent insecticidal, Allium sativum leaf agglutinin (ASAL) in important pulse crop, chickpea (Cicer arietinum L.) to resist the phloem feeding Aphis craccivora
(SPRINGER, 2009-08)The phloem sap-sucking hemipteran insect, Aphis craccivora, commonly known as cowpea aphid, cause major yield loss of important food legume crop chickpea. Among different plant lectins Allium sativum leaf agglutinin (ASAL), ... -
