This species was sequenced as a part of the Aspergillus whole-genus sequencing project - a project dedicated to performing whole-genome sequencing of all members of the Aspergillus genus. The Aspergilli is a ubiquitous and species-rich genus, currently containing more than 300 filamentous fungi. The genus covers a wide range of phenotypes and has a substantial economic foot print, as it includes fermenters of foodstuffs, key cell factories for production of enzymes and organic acids, plant pathogens, model organisms for cell biology, human opportunistic pathogens, producers of animal and human mycotoxins, and degraders of a wide range of organic biomass relevant for bioenergy conversion.

Aspergillus ochraceoroseus (MB 309373)

A. ochraceoroseus Bartoli & Maggi was described in Trans Br Mycol Soc 71: 383-394, 1979 (on page 393). It has only been found once in the Taï National Forest in Ivory Coast. Of particular interest is the production of large amounts of aflatoxin B1 in this species (Frisvad et al., 1999, In Tuijtelaars et al. (eds.) Food Microbiology and Food Safety into the Next Millenium, Zeist, p. 125-126; Klich et al., Appl Microbiol Biotechnol 53: 605-609, 2000). Because this species is phylogenetically relative unrelated to A. flavus, the question of whether the gene clusters and their regulation developed independently or via horizontal gene transfer and whether aflatoxins are co-regulated with different secondary metabolites in the two species.
