Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in r ....Mechanisms of arsenic tolerance in plants: how do symbiotic arbuscular mycorrhizal (AM) fungi reduce uptake? Arsenic contamination of soil is a major problem caused by irrigation with contaminated ground-water, mining and application of pesticides. Plant uptake leads to entry into food chains, with severe consequences for crop growth and human health. This project will aid the search for mechanisms to reduce plant arsenic accumulation by exploring roles of beneficial plant-fungus symbioses in reducing uptake. Results will be relevant to most crop plants, because of the widespread occurrence of the symbioses. The project will enhance collaboration with China where arsenic toxicity is prevalent, provide education and training in an internationally recognised laboratory and enhance Australia's reputation for tackling soil contamination.Read moreRead less
