Unlocking blight pathogen’s evolutionary secrets could provide key to better disease control

Scientists say they have discovered vital clues as to how the potato blight pathogen adapted to spread between different plant species. Researchers at Oxford University and The Sainsbury Laboratory, Norwich, looked at how phytophthora infestans evolved to target other plants. The findings could help in the development of new blight-resistant potato varieties. The study is said to be the first to show how pathogens switch from targeting one species to another through changes at a molecular level. More
