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. linkurl:T.

Species: A golden alga, Aureococcus anophagefferens Genome size: 56 million base pairs Interesting fact: This species, which causes brown tides that threaten fisheries and coastal marine life, has a larger genome than other...
