Evolution of aflatoxin gene cluster

Blogging on Peer-Reviewed ResearchIgnazio Carbone and colleagues published a recent analysis of the evolution of the aflatoxin gene cluster in five Aspergillus fungi entitled “Gene duplication, modularity and adaptation in the evolution of the aflatoxin gene cluster” in BMC Evolutionary Biology. [...]

Exploring a global regulator of gene expression in Aspergillus

Blogging about Peer-Reviewed ResearchWhen first discovered, the gene LaeA was thought to be a master switch for silencing of several NRPS secondary metabolite gene clusters in Aspergillus. NRPS and PKS are important genes in filamentous fungi as they produce many compounds that likely help fungi compete in the ecological niche mycotoxins (e.g. aflatoxin,
