The fungal genus Cochliobolus includes 19 species,[1] it includes some plant pathogenic species such as Cochliobolus heterostrophus. A lot of former Cochliobolus species were transferred to either Curvularia or Bipolaris genera.[1]

Cochliobolus heterostrophus is known from "southern corn blight" which affects corn and maize.[2]

Heterothallism and homothallism

[edit]

Those fungi that need a partner to mate are referred to as heterothallic (self-sterile), and those fungi not needing a partner are referred to as homothallic (self-fertile). A study of DNA sequences of mating type loci from different heterothallic and homothallic species in the genus Cochliobolus suggests that homothallism can be derived from heterothallism by recombination.[3]
