Rice seedlings grown under 50 μM cadmium alone or in combination with 5 μM methyl jasmonate were investigated for Cd-induced oxidative injury at 3, 7 and 10 days of treatment. MeJA treatments alone did not have any significant change in antioxidant enzyme activities or levels of H2O2 and O2(·-) in roots/shoots, as compared to controls during 3-10 days. The(More)
At the subcellular level, the synthesis of ceramide from free lignoceric acid and sphingosine in brain required reconstituted enzyme system (particulate fraction, heat-stable and heat-labile factors) and pyridine nucleotide (NADPH). The mitochondrial electron transfer inhibitors (KCN and antimycin A), energy uncouplers (oligomycin and 2,4-dinitrophenol),(More)
Enhanced disease susceptibility 1 (EDS1), a plant-specific protein has homology with the eukaryotic lipase in their N-terminal halves and a unique domain at its C-termini. EDS1 is known to be an important regulator of biotic stress and an essential component of basal immunity. EDS1 interacts with its positive co-regulator phytoalexin deficient 4 (PAD4),(More)
Role of salicylic acid in plants grown under metal contaminated soil is not yet understood. To investigate if signaling by Cd-induced H2O2 or SA, collide or integrate, rice cv. HUR3022, grown for 3, 7 and 10 day under 50 µM Cd/SA alone or in combination were studied. Dynamic distribution of Cd2+ and SA, cell viability, time-dependent changes in H2O2 levels,(More)
Binding interactions of cadmium (Cd) with rice ascorbate peroxidase (OsAPX) in presence or absence of jasmonate was examined in-silico. OsAPX is a 250 amino acid long protein with 90 % sequence similarity to soybean-APX. The 3D model of OsAPX obtained by homology modeling using soybean APX (PDBID:1OAF) as template was associated with −15975.85 kJ/mol(More)
Knowledge of rice genome brings new dimensions to the management of abiotic stresses; however, gene sequences in the rice genome are yet to be assigned structure and function. Hydrogen peroxide, salicylates and jasmonates act as signal molecules in plants employing common machinery to manage abiotic stress. The present work is primarily focused to assign a(More)
The present work deals with the fatigue crack growth simulation of alloy/ceramic functionally graded materials (FGMs) using extended finite element method (XFEM). Various cases of FGM containing multiple inhomogeneities/discontinuities along with either a major edge or a center crack are taken for the purpose of simulation. The fatigue life of the FGM plate(More)
