Editorial: Effects of microplastics on soil ecosystems

Tiny plastic particles called microplastics are accumulating in soil worldwide and causing problems for the microorganisms that keep soil healthy. This editorial reviews research showing that while newer biodegradable plastic mulches used in farming are better than traditional plastics, both types can weaken the complex networks of beneficial soil microbes. Scientists found bacteria that can break down some plastic chemicals, but long-term solutions require better monitoring and ways to manage plastic residues in agricultural soils.

Gene transfer between fungal species triggers repeated coffee wilt disease outbreaks

A new study reveals that coffee wilt disease, which has destroyed coffee crops across Africa, emerges repeatedly because of gene-swapping between different fungal species. Scientists discovered that large chunks of DNA called ‘Starships’ act like genetic delivery vehicles, transferring disease-causing genes from one fungus to another. This genetic exchange allows the pathogen to adapt and infect different coffee plant species, causing successive outbreaks. Understanding this mechanism could help protect global coffee production in the future.
