This research reveals how certain fungi called Trichoderma developed their remarkable ability to feed on both plant matter and other fungi. The study found that Trichoderma acquired genes from other fungi through a process called lateral gene transfer, which gave them new capabilities to break down plant material. This discovery has important implications for everyday life: • Better understanding of how to use Trichoderma fungi in agriculture as natural pesticides against harmful fungi • Improved production of industrial enzymes used in biofuel production and other applications • Development of more effective biological methods for decomposing plant waste • Insights into evolution that could help develop new biotechnology applications • Better ways to harness these fungi for sustainable agriculture and industry
