The rabbit ciliary body-iris preparation in vitro shows concentrative uptake of C-proline which is resistant to anoxia and to cyanide; inhibited by ouabain; and abolished in the absence of external sodium or by cold (0° C). It has a Q,o (27 to 37° C.) of 1.7. Uptake is decreased by preloading with unlabeled proline. Exchange diffusion of the accelerative type is demonstrable during efflux of >C...

application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. nanofertilizers application could be a suitable way to reduce these problems. accordingly, in order to assess the silicon nanopar...

Calli of soybean [Glycine max cv. Pershing] were grown on "MS" media supplemented with different levels of KCl and NaH2PO4 for 45 days. The effects of salt stress were evaluated on the production and accumulation of proline and growth content of calli. Proline content increased as growth occurred. The maximum amount of proline and the highest content of growth were observed in calli grown on me...

In order to survey effect of salinity and cadmium on catalase and peroxidase enzymes activity , proline accumulation, Malondialdehyde and protein content variation in  Brassica oleracea an experiment was conducted in green house condition factorial design based on completely random block in 2014 year. The first factor was cadmium at four levels (0, 50, 100 and 200 ppm) and second factor was sal...

Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...

Excised bean (Phaseolus vulgaris) leaves were used to measure changes in proline content and proline metabolism during rehydration in the dark after the leaves had been incubated in the dark 24 hours in a wilted condition.The increase in nonprotein proline which occurs in wilted leaves stopped immediately upon rehydration, and thereafter levels of proline declined. The rate of decline and the f...

introduction dehydration is one of the limiting factors of crop production. it results from increasing the amount of water losses from leaf or inadequate water absorption rate or combination of both. zinc used in many enzymes of the plant tissues and have catalytic role in activation of some enzymes. zinc is involved in the synthesis and degradation of proteins and is an essential micronutrien...

This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...
