This study compared the protective effect of cold acclimation on tolerance in lotus (Nelumbo nucifera). The increased sprouting rate and leaf expansion by about 36% at 0 °C, could enhance levels stress related osmolytes including higher proline, soluble protein, sugar contents. electrolyte leakage lipid peroxidation level control samples significantly, but these indices did not change signific...

Abstract As photolithoautotrophs, cyanobacteria are key to a future photobiotechnology. We studied the capacity of Synechocystis sp. PCC 6803 produce trans -4-hydroxy-L-proline, valuable chiral synthon using oxygenic photosynthesis and recombinant L-proline-4-hydroxylase. At scale, such process would use comparable area land heterotrophic one if sugar is also considered. Phototrophs offer huge ...

Elucidating the effect of soil moisture on adaptation dominant plants in coastal wetlands is important for predicting evolution vegetation region. In this paper, Tamarix chinensis , a species Yellow River Delta, was used as object to study changes its growth and physiological parameters with increasing salinity under different conditions (normal watering, persistent drought waterlogging). Diffe...

1. After incubation of chick-embryo skin slices with [(14)C]proline for 2hr. the specific activities of [(14)C]proline and [(14)C]hydroxyproline in soluble and insoluble collagens and [(14)C]proline in non-collagenous proteins were determined as well as the total amounts of both imino acids in these proteins. On the basis of these results it was demonstrated that soluble collagens having a high...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

limited water for irrigation and the coincidence of early growth of sugar beet (beta vulgaris l.) with the late growth of winter cereals in the northeast (ne) of iran, force farmers, to allocate their limited irrigation water to the cereal crops and thus their sugar beet crop is subjected to an early water stress. finding cultivars which are able to withstand early water stress without a si...

to determine the effect of zn and mn enriched seed on quality of two winter safflower varieties under drought stress, an experiment was conducted at the agricultural faculty research field, tarbiat modarres university, during 2004-2005 cropping season. the design was a split factorial randomized complete block one of 3 replications. main plots were composed of 3 different levels of drought stre...

effects of seed priming by salicylic acid on some morpho-physiologic characteristics and yield of cowpea (vigna unguiculata l.) cultivar “parastou” was investigated under water deficit. experiment was conducted as a split block design with 3 replications in 2008-2009 at research farm of zanjan university. factors were including drought stress as a main factor in 2 levels (irrigation, water defi...

Studies show that Oryza sativa L. contains a structure named β-glucan with anti cancer properties. In the present study, a tissue culture for rice was carried out and β-glucan content was measured under various sugar and vitamin levels in basic MS medium. Seeds of Hashemi cultivar were cultured on MS medium. Two plant hormones, namely, 2,4-D (0, 1, 1.5, 2 and 3 mg/l) and kinetin (0,0.5, 1, and ...
