At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...

Successful production and development of stable and adaptable genotypes only depend on the positive results achieved from the interaction between genotype and environment that consequently has a significant impact on breeding strategies. In this regard, we conducted an experiment to study genotypic differences of 16 lines durum wheat under both zinc sufficient and deficient stress during 2014-2...

Low zinc (Zn) availability and its absorption limit wheat production and quality of yield in calcareous soils. In order to identify Zn deficient stress tolerance in wheat, fifteen spring genotypes (Diyarbakir-81; Gediz-75; Svevo; Zenit; Amanos-97; Fuatbey-2000; Balcali-2000; Ceylan-95; Firat-93; Aydin-93; Ozbek; Artuklu; Akcakale-2000; Aday-19; and Ege-88) were evaluated under two conditions (n...

OBJECTIVE Zinc deficiency is a problem world-wide. Zinc and insulin are intimately related, and a reduced zinc intake may affect glucose metabolism. The present study investigates how subclinical zinc deficiency in rats affects glucose metabolism and zinc distribution in the pancreas. METHODS Glucose metabolism was evaluated by blood-glucose, serum insulin, homeostasis model assessment (HOMA)...

Zinc deficiency is known to be associated with insulin resistance in obese individuals. This study was performed to evaluate the effect of zinc supplementation on insulin resistance and metabolic risk factors in obese Korean women. Forty obese women (body mass index (BMI) ≥ 25 kg/m(2)) aged 19-28 years were recruited for this study. Twenty women of the study group took 30 mg/day of supplemental...

BACKGROUND Recently, experimental zinc deficiency has been correlated with depression-like alterations in rodents. METHODS In the first part of present study, the time course of zinc deficient diet induced alterations in the tail suspension test (TST) in mice was investigated. In the second part, the effect of imipramine and escitalopram in control and zinc-deprived for 3 weeks mice was exami...

BACKGROUND Zinc is an essential trace element with a prominent role in human nutrition. Zinc deficiency has been linked to growth retardation, hypogonadism in males, and lack of sexual development in females. It ranges from 50% in sub-Saharan Africa to 5% in high income countries. The aim of this study is to evaluate the prevalence of zinc deficiency in healthy children in Shiraz, southern Iran...

Zinc deficiency reduces intake and produces an unusual approximately 3.5-d cycle of intake in rats. The mechanism underlying the anorexia and cycling has not yet been defined; current hypotheses suggest that alterations in amino acid metabolism and neurotransmitter concentrations may be a part of this anorexia. Recent reports indicate that appetite-stimulating neuropeptide Y (NPY) may be elevat...

the purpose of this study was to evaluate the effect of two regimes during rats' gestation and lactation on learning, memory and motor function of their offspring. for this purpose, female rats (albino-wistar) were obtained from pasteur institute, iran. after mating, 12 pregnant rats were divided into three groups and they had their special regimes during their last week of pregnancy as we...

Zinc (Zn) as a nutritional factor affects the health of the oral tissues. This study was done for the evaluation of the effects of zinc deficiency on the oral tissues of rats. The study was carried out on 14 male Wistar rats, cessation of lactation on the 24th day after birth. The rats were randomly divided into two groups. Zinc deficient (ZD) diet was used for one group and another group was f...
