zagros (drought tolerant) and pishtaz (drought susceptible) cultivars were classified on the basis of shoot dry weight and were used as plant material in this study. total chlorophyll, carotenoids, antocyanins, proline, soluble sugar contents, lipid peroxidation, antioxidant enzyme activities and protein patterns were determined. seedlings of wheat genotypes were grown in nutrient solution cult...

The present study deals with the effects of allelochemicals present in leachate on the drought response of maize plants. Nicotiana plumbaginifolia was selected as a donor plant. 12-d-old maize (Zea mays L. cv. Uttam) seedlings with and without leachate were subjected to water stress (WS) by withholding water supply for 6 days. Leaf water status, photosynthetic pigments, protein content, proline...

1. The catabolism of L-[1-14C]phenylalanine was used to indicate the effects of single amino acid supplementation of an inadequate protein diet (200 g crude protein (nitrogen x 6.25)/kg) on the utilization of dietary amino acids in pigs of 2.5 kg body-weight reared on an adequate protein diet (240 g crude protein/kg) containing skim milk and a mixture of free amino acids. 2. The oxidation of ph...

ABSTRACT- Heat stress causes flower and fruit abscission in pepper. This study was conducted in the greenhouses of Isfahan University of Technology to evaluate the effect of foliar application of Benzyl adenine (BA) and potassium silicate (K2SiO3) under heat stress condition on bell pepper. Two factorial experiments based on completely randomized design with four concentrations of BA (0, 0.06, ...

Regeneration of explants plays a significant role in plant transformation. Explant type, hormonal concentration, and pre-culturing period are important in transformation efficiency. To get an efficient transformation of canola and optimize regeneration conditions, different explants along with different culture media were studied. Four canola varieties were used to evaluate regeneration ability...

Hypocitrullinemia and hypoargininemia but hyperprolinemia are associated with elevated plasma concentration of lactate in infants. Because the small intestine may be a major organ for initiating proline catabolism via proline oxidase in the body and is the major source of circulating citrulline and arginine in neonates, we hypothesized that lactate is an inhibitor of intestinal synthesis of cit...

The PutA protein is both the put repressor and a membrane-bound enzyme with proline and delta 1-pyrroline-5-carboxylate dehydrogenase activities. The conditions required for association of purified PutA protein with membrane vesicles suggested that a redox switching mechanism might determine the proportion of PutA protein functioning as a dehydrogenase (Wood, J. M. (1987) Proc. Natl. Acad. Sci....

this study was aimed to assess of priming effects on soluble proteins and antioxidant enzymes of as a nigella sativa medicinal plant under different levels of salinity and drought. two greenhouse factorial experiments with three replicated randomized complete block design were conducted.treatments included five levels of priming (potassium nitrate 1% and salicylic acid 0.2 mm in 6 hours, potass...
