Several amino acids were found to stimulate glycogen synthesis and lipogenesis, and to inhibit ketogenesis in isolated rat hepatocytes. When hepatocytes were incubated in the presence of 20 mM-glucose, the amino acids could be classified in decreasing order of efficiency as follows: glutamine and proline, alanine, aminoisobutyric acid, asparagine and histidine for stimulation of glycogen synthe...

plant tissue culture techniques were used to study the effect of nacl on tropane alkaloids accumulation and proline content of both datura metel and datura stramonium. callus cultures were established for both datura species. however, ms medium supplemented with 1mg/l of both ba and naa was the best for callus production in d. metel, while ms supplemented with 3 mg/l kin and 1 mg/l 2, 4-d was t...

Proline concentration has been often suggested as an indicator of osmotic stress. A better understanding of the genetics of this trait is however needed. In the present study, proline concentration has been assessed, together with root and stem growth, potassium, calcium and total soluble sugars concentration and stress injury symptoms, in seedlings of sunflower hybrids and their parents grown ...

salinity is one of the major environmental stresses that limit plant growth and productivity. glasswort (salicornia herbacea l.) is one of the native halophytic plants of iran that widely spread in salt areas. the purpose of this study was to determine the physiological and growth responses of s. herbacea to salinity stress. plastic pods (15 cm diameter, 20 cm height) with the silica sand bed w...

In this study, we demonstrate that two of the osmolytes utilized in the osmoconforming strategy of larval Culex tarsalis are regulated by two fundamentally different signals. When the external osmolality was increased using salinity (sea salts), hemolymph NaCl, proline and trehalose concentrations increased significantly. When sorbitol was used to increase the external osmolality without an ele...

  Abstract Two experiments with factorial arrangements on the basis of randomized complete block design in three replications were conducted in 2007 and 2008, to evaluate chlorophyll content index (CCI), fluorescence of chlorophyll, proline content and grain yield of three soybean cultivars (Williams, Zan and L17) under a non-saline (control) and three saline (3, 6 and 9 ds/m NaCl) conditions...

introduction   heavy metal contamination has disastrous effects on plant productivity and threatens human and animal health. among metals, cadmium (cd) is commonly released into the environment from industrial processes. cd is known to cause cellular damage in plants by producing oxidative stress via the over-production of reactive oxygen species (ros). to combat oxidative damage, plants have d...
