Integration of physio-biochemical, biological and molecular approaches to improve heavy metal tolerance in plants

mycolabadmin

Heavy metals in soil can poison plants and damage crops, reducing food safety. Plants have natural defense systems that can be strengthened through adding minerals like silicon and boron, applying plant hormones, using specially designed nanoparticles, and improving soil quality. This review explains how different combinations of these approaches can help plants survive in contaminated soil and produce safer food.

Heavy Metal-Contaminated Soils and Gastric Cancer Risk: Molecular Insights and the Relevance of a One Health Perspective

mycolabadmin

Heavy metals like cadmium, arsenic, and lead contaminate agricultural soils and accumulate in crops such as rice and vegetables, which people consume as part of their daily diet. These metals damage stomach cell DNA and trigger inflammation, increasing cancer risk, especially when combined with bacterial infections like H. pylori. A comprehensive approach monitoring soil quality, crop safety, and human health together can help prevent this disease and protect communities from contamination.

Ni2+ and Cd2+ Biosorption Capacity and Redox-Mediated Toxicity Reduction in Bacterial Strains from Highly Contaminated Soils of Uzbekistan

mycolabadmin

Researchers in Uzbekistan discovered three types of bacteria that can remove dangerous heavy metals like cadmium and nickel from contaminated soil. These bacteria work by clinging to the metal particles on their surfaces and even chemically transforming them into less harmful forms. The study found that these bacteria work best at neutral pH and warmer temperatures, making them promising candidates for cleaning up polluted environments naturally and affordably.

The Importance of Humic Acids in Shaping the Resistance of Soil Microorganisms and the Tolerance of Zea mays to Excess Cadmium in Soil

mycolabadmin

This research explores how humic acids, which are natural organic substances found in soil, can help protect plants and soil bacteria from cadmium, a toxic heavy metal. When cadmium contaminated soil, the application of humic acid preparation called Humus Active promoted the growth of specialized bacteria that can tolerate and break down cadmium. As a result, corn plants grew better and maize biomass increased significantly when the soil was treated with the humic preparation, suggesting this is a practical solution for farming on contaminated land.

Nitric Oxide-Mediated Regulation of Chitinase Activity and Cadmium Sequestration in the Response of Schizophyllum commune to Cadmium Stress

mycolabadmin

Schizophyllum commune is an edible mushroom with health benefits, but cadmium pollution threatens both the fungus and human health. Researchers discovered that when exposed to cadmium, the mushroom produces a signaling molecule called nitric oxide that makes its cell wall enzymes more active, causing cadmium to accumulate in the cell wall and damaging the fungus. By controlling nitric oxide levels, scientists could potentially make these fungi more resistant to heavy metal pollution and safer for consumption.

Paraboremia selaginellae enhances Salvia miltiorrhiza growth and cadmium tolerance via modulating root architecture and cadmium speciation in contaminated environments

mycolabadmin

A beneficial fungus called Paraboremia selaginellae was found to help medicinal plants grow better in soil contaminated with cadmium, a toxic heavy metal. When this fungus colonizes plant roots, it reduces how much cadmium the plant absorbs and improves the soil’s nutrient content. This natural approach offers a promising solution for growing medicinal plants safely in polluted soils without expensive chemical treatments.

Melatonin-Producing Microorganisms: A Rising Research Interest in Their Melatonin Biosynthesis and Effects on Crops

mycolabadmin

Scientists are discovering that certain microorganisms like yeast, algae, and bacteria naturally produce melatonin, the same molecule that helps humans sleep. These melatonin-producing microbes could help farmers grow healthier crops by sharing their melatonin with plants and protecting them from stress like drought and disease. This discovery offers an eco-friendly alternative to synthetic melatonin and could make agriculture more sustainable as climate change poses increasing challenges.

Cadmium and Lead Tolerance of Filamentous Fungi Isolated from Contaminated Mining Soils

mycolabadmin

Researchers found several types of fungi thriving in extremely contaminated mining soils in Mexico. These fungi can survive in environments with toxic levels of lead and cadmium that would kill most organisms. The most promising fungus, Paecilomyces lilacinus, can tolerate both metals and could potentially be used to clean up heavily polluted mining sites by binding and immobilizing these dangerous metals in the soil.

Bioaccumulation and physiological changes in the fruiting body of Agaricus bisporus (Large) sing in response to cadmium

mycolabadmin

This research shows that button mushrooms (Agaricus bisporus) can absorb and accumulate harmful cadmium from contaminated soil. When exposed to cadmium stress, the mushrooms increase their protective chemical defenses, including antioxidant enzymes and organic acids, to survive the toxic conditions. The study demonstrates that these edible mushrooms could potentially be used as a practical and cost-effective method to clean up cadmium-polluted soils.

Symbiotic Fungus Serendipita indica as a Natural Bioenhancer Against Cadmium Toxicity in Chinese Cabbage

mycolabadmin

This research shows that a beneficial fungus called Serendipita indica can help Chinese cabbage plants survive cadmium contamination. When the fungus colonizes plant roots, it triggers the plant’s natural defense systems to produce protective compounds and reduce heavy metal damage. This finding offers farmers an eco-friendly, biological solution for growing vegetables safely in contaminated soils without harmful chemical treatments.
