The present work describes the intrachloroplast localization and the changes that took place in the thylakoid and stroma-located superoxide dismutases (SOD, EC 1.15.1.1) and ascorbate peroxidases (APX, EC 1.11.1.11), in response to long-term NaCl stress in Pisum sativum L. cv. Puget plants. Native PAGE using high chloroplast protein concentrations pointed to the presence of the two main Fe-SODs...

In order to evaluate effect of salinity on germination and early seedling growth of lentils a laboratory experiment was conducted at Biotech Research Center of the University of Zabol, in 2011. The experimental design was a completely randomized with five NaCl solution, together with seven replicates. The seeds were germinated in Petri dishes, on with 10 mL of either double-distilled water (con...

The solvation of sugars in aqueous media matters the understanding biological systems and carbohydrate transformations. presence NaCl is known to perturb hydrogen bonding sugar hydrates, however, direct evidence elucidate mechanism at atom level very rare even though “NaCl Effect” was well biomass transformations for chemicals/biofuels. Here we report experimental evidences a clear staircase-li...

Using small-angle neutron scattering (SANS), we have measured the salt-dependent static structure factor of di- and trinucleosomes from chicken erythrocytes and from COS-7 cells. We also determined the sedimentation coefficients of these dinucleosomes and dinucleosomes reconstituted on a 416-bp DNA containing two nucleosome positioning sequences of the 5S rDNA of Lytechinus variegatus at low an...

Weanling Dahl salt-sensitive (DS) and salt-resistant (DR) rats were used to compare effects of feeding high or low NaCl diets on taste preference for, and intake of, a wide range of saline concentrations. The DS and DR were fed either 8.0 or 0.4% dietary NaCl for 4 weeks. Then, with all animals fed the 0.4% NaCl diet, their taste preferences for 0.0001 to 0.56 M saline were assessed using three...

Seeds of Indian mustard (Brassica juncea (L.) Czern. et Coss.) were exposed to 0, 50, 100 and 150 mmol/L NaCl for 8 h and seeds were sown in an earthen pot. These stressed seedlings were subsequently sprayed with 10 micromol/L salicylic acid (SA) at 30 d and were sampled at 60 d to assess the changes in growth, photosynthesis and antioxidant enzymes. The seedlings raised from the seeds treated ...

Osmotic shock with sequential 30-minute treatments in ice-cold saline solutions and H(2)O released proteins from excised barley roots and inhibited the subsequent uptake of orthophosphate (Pi). The amount of protein released increased sharply at NaCl concentrations above 0.05 molar, approximately the threshold concentration above which Pi uptake was increasingly suppressed. About 60% of the nea...
