In vitro proliferated shoot culture of six grape genotypes (Vitis vinifera L.) were screened for tolerance to NaCl (0 to 200 mM). The cv. Perlette was found to tolerate 175 mM NaCl followed by cvs. Pusa Seedless and Beauty Seedless 150 mM NaCl. Na, K, Cl, Ca and Mg content increased upto 100 mM NaCl in most of the genotypes. Total sugar and proline content(More)
Protein tyrosine nitration (PTN) is a selective post-translational modification often associated with pathophysiological conditions. Although yeast cells lack of mammalian nitric oxide synthase (NOS) orthologues, still it has been shown that they are capable of producing nitric oxide (NO). Our studies showed that NO or reactive nitrogen species (RNS)(More)
Nitrosative stress has various pathophysiological implications. We here present a detailed characterization on the effect of nitrosative stress in Saccharomyces cerevisiae wild-type (Y190) and its isogenic flavohemoglobin mutant (Deltayhb1) strain grown in presence of non fermentable carbon source. On addition of sub-toxic dose of nitrosating agent both the(More)
Bioassay-guided purification of sulphated polysaccharides from a green marine alga, Codium dwarkense, yielded two products, which contained sulphated arabinan and sulphated arabinogalactan. The product containing arabinan sulphate exhibited stronger blood anticoagulant activity than the one containing sulphated arabinogalactan.
BACKGROUND Pollen counts are widely used by television stations in news programming but little is known about the sources for and quality of this information. OBJECTIVE The purpose of this investigation was to survey television meteorologists about their sources for pollen counts and to assess their general understanding of these data. METHODS(More)
The PPO activity and content of phenolic compounds were estimated during the different growing seasons and developmental age of shoots in seven grape genotypes. Both, the total phenol content and catecholase activity were found significantly affected by the growing season, developmental age of shoot and the genotype. But, season as well as age of shoot(More)
Malaria remains one of the most serious infectious diseases in the world. There are five human species of the Plasmodium genus, of which Plasmodium falciparum is the most virulent and responsible for the vast majority of malaria related deaths. The unique biochemical processes that exist in Plasmodium falciparum provide a useful way to develop novel(More)
Single-nucleotide polymorphisms (SNPs), a most common type of genetic mutations, result from single base pair alterations. Non-synonymous SNPs (nsSNP) occur in the coding regions of a gene and result in single amino acid substitution which might have the potential to affect the function as well as structure of the corresponding protein. In human the(More)
Catecholase and cresolase (PPO) enzyme activities and phenolic content were measured in different mango cultivars at panicle initiation. Enzyme activity and phenolic content varied widely amongst eight cultivars, the maximum being in Bhadauran and minimum in Tommy Atkins. Floral malformation incidence was maximum (53.75%) in `Tommy Atkins' and minimum in(More)
This report provides for the first time a novel environment friendly extracellular synthesis of stable silver nano-bioconjugates (SNBCs) at room temperature at pH 5.0 using Penicillium citrinum MTCC 9999 biomass. The UV-Visible spectral scan of dispersed SNBCs solution showed absorption in the region 340–450 nm due to surface plasma resonance (SPR). Typical(More)
