Impact of heavy metal stress on plants and the role of various defense elements
Heavy metal (HMs) pollution is currently one of the serious issues for the environment and agriculture as it has a direct impact on the production yield. This situation has gained a rapid momentum in the present era due to the population pressure, industrialization, and various anthropogenic activities which in turn lead to oxidative ...
متن کاملResponses of Plant Proteins to Heavy Metal Stress—A Review
Plants respond to environmental pollutants such as heavy metal(s) by triggering the expression of genes that encode proteins involved in stress response. Toxic metal ions profoundly affect the cellular protein homeostasis by interfering with the folding process and aggregation of nascent or non-native proteins leading to decreased cell viability. However, plants possess a range of ubiquitous ce...
متن کاملThe Influence of Mycorrhiza and Edta Application on Heavy Metal Uptake by Different Maize Varieties
This study investigated whether mycorrhizal colonization influences heavy metal uptake by maize. Two experiments were carried out. In the first, 15 commercially available maize varieties cultured on industrial waste substratum and inoculated or not with Glomus intraradices, were treated one week before harvest with EDTA, a chelating agent known to mobilize heavy metals in soil. Estimation of my...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولTowards Understanding Plant Response to Heavy Metal Stress
Metals like zinc, iron and copper are essential micronutrients required for a wide range of physiological processes in all plant organs for the activities of various metal-dependent enzymes and proteins. However, they can also be toxic at elevated levels. Metals like arsenic, mercury, cadmium and lead are nonessential and potentially highly toxic. Once the cytosolic metal concentration in plant...
