Distribution of ppo and lox genes amongst four different Aspergillus species. The black box indicates the presence of the ppo gene. The blue box indicates the presence of a lox gene coding for an intracellular LOX, and the yellow box represents a lox gene coding for an extracellular LOX. A. nidulans and A. niger have three different ppo genes. A. flavus has four different ppo genes and a lox gene. A. fumigatus has three different ppo genes and two lox genes.
