نقش سیلیکون در کاهش تنش کمبود و سمیت آهن در کشت هیدروپونیک گیاه برنج (Oryza sativa L.)
Silicon (Si) nutrition may alleviate biotic and abiotic stresses including heavy metal deficiency and toxicity in plants. Iron deficiency and toxicity are important limiting factors in growth of rice. In the present study, role of Si nutrition on alleviation of iron deficiency and toxicity was investigated in rice plants. Plants were cultivated in greenhouse in hydroponics, using Yoshida soluti...
متن کاملLead exposure, interactions and toxicity: food for thought.
The recognition that nutritional status plays a role in altering susceptibility to lead absorption and toxicity has triggered the development of this review. There has been a significant increase worldwide in awareness and concern about the effects of lead on human health and the environment over the last two decades. Both occupational and environmental exposures to lead remain a serious proble...
متن کاملAnemia, Iron Deficiency Anemia and Lead Poisoning in Children with Opioid Toxicity: A Study in North East of Iran
Background: Opium is a new source of lead and considered as a cause of lead poisoning. As anemia and lead poisoning affect growth and behavior negatively, their timely prevention, diagnosis, and treatment are essential. The aim of thi study is evaluation of the prevalence of anemia, iron deficiency anemia, and lead poisoning in children with opioid toxicity. Materials and Methods: In this cr...
متن کاملSome observations on the interaction of zinc, copper, and iron metabolism in lead and cadmium toxicity.
A brief review of the literature indicates that nutritional deficiencies have been shown to increase the absorption and toxicity of orally ingested lead and cadmium. Results from recent studies indicates that low level oral ingestion of cadmium and lead perturbs the metabolism of zinc, copper, and iron and that these changes may be the earliest manifestation of the toxicity of lead and cadmium....
متن کاملOptimal copper supply is required for normal plant iron deficiency responses.
Iron (Fe) and copper (Cu) homeostasis are tightly linked across biology. Understanding crosstalk between Fe and Cu nutrition could lead to strategies for improved growth on soils with low or excess metals, with implications for agriculture and phytoremediation. Here, we show that Cu and Fe nutrition interact to increase or decrease Fe and/or Cu accumulation in leaves and Fe uptake processes. Le...
