Heavy-metal stress and developmental patterns of arbuscular mycorrhizal fungi.
The rate of global deposition of Cd, Pb, and Zn has decreased over the past few decades, but heavy metals already in the soil may be mobilized by local and global changes in soil conditions and exert toxic effects on soil microorganisms. We examined in vitro effects of Cd, Pb, and Zn on critical life stages in metal-sensitive ecotypes of arbuscular mycorrhizal (AM) fungi, including spore germin...
متن کاملPlants and arbuscular mycorrhizal fungi: an evolutionary-developmental perspective.
Arbuscular mycorrhizas (AMs) are widespread symbiotic associations that are commonly described as the result of co-evolution events between fungi and plants where both partners benefit from the reciprocal nutrient exchange. Here, we review data from fossil records, characterizations of AM fungi in basal plants and live cell imaging of angiosperm colonization processes from an evolutionary-devel...
متن کاملProspects of arbuscular mycorrhizal fungi in phytoremediation of heavy metal contaminated soils
Arbuscular mycorrhizal (AM) associations are integral, functioning parts of plant roots and are widely recognized as enhancing plant growth on severely disturbed sites, including those contaminated with heavy metals. They are reported to be present on the roots of plants growing on heavy metal contaminated soils and play an important role in metal tolerance and accumulation. Isolation of the in...
متن کاملArbuscular Mycorrhizal Fungi: a Potential Biotechnological Tool for Phytoremediation of Heavy Metal Contaminated Soils
High concentrations of heavy metals in the soil have detrimental effects on ecosystems and are a risk to human health as they can enter the food chain via agricultural products or contaminated drinking water. Phytoremediation is the direct use of living plants for in situ remediation of metal contaminated soil, sludges, sediments and ground water through contaminant removal, degradation or cont...
متن کاملArbuscular mycorrhizal fungi in alleviation of salt stress: a review.
BACKGROUND Salt stress has become a major threat to plant growth and productivity. Arbuscular mycorrhizal fungi colonize plant root systems and modulate plant growth in various ways. SCOPE This review addresses the significance of arbuscular mycorrhiza in alleviation of salt stress and their beneficial effects on plant growth and productivity. It also focuses on recent progress in unravelling...
