These mycorrhizal fungi efficiently supply their plant partners with phosphate and other essential minerals. Recently, scientists at the Leibniz Institute of Plant Biochemistry (IPB) in Halle, in collaboration with partners at the University of Bonn, discovered a molecular switch that detects the plant's phosphate content and signals whether to initiate or inhibit the symbiosis. This signaling pathway could enable plants to form partnerships with soil fungi even when sufficient phosphate is available. The study, published in the renowned journal Science Advances, offers a potential solution to a long-standing agricultural problem and opens new avenues for reducing fertilizer use. 

Cadmium contamination in paddy soils is a serious global food safety concern, threatening the health of millions who rely on rice as a staple. While cleaning up contaminated soil is often impractical, a team of scientists has demonstrated an effective and agronomically simple alternative: spraying rice leaves with a solution of tiny, engineered carbon dots (CDs).

In a field experiment on moderately cadmium-contaminated soil, researchers from the Beijing Academy of Agriculture and Forestry Sciences and Jiangnan University applied CDs to rice canopies. The application produced remarkable results. The higher-dose treatment not only reduced the cadmium accumulated in the rice grains by 46% but also increased the overall grain yield by 18%, all without harming the grain's nutritional quality.

A study led by researchers from the Department of Microbiology at the University of Malaga has revealed how organic farming –the one that uses natural substances and processes, avoiding the use of synthetic chemicals– can, in the long term, help crops become more resistant to drought in a natural way.
