Species: A pathogenic fungus,
Leptosphaeria maculans Genome size: 45 million base pairs Interesting fact: This fungus causes stem canker in cruciferous vegetables such as broccoli, cabbage, and bok choy, and is a major threat to oilseed rape, which is used to produce canola oil, animal feed, and biofuel.
