Regulation of plant biomass utilization in Aspergillus.

The ability of fungi to survive in every known biotope, both natural and man-made, relies in part on their ability to use a wide range of carbon sources. Fungi degrade polymeric carbon sources present in the environment (polysaccharides, proteins, and lignins) to use the monomeric components as nutrients. However, the available carbon sources vary strongly in nature, both between biotopes and in time. The degradation of polymeric carbon sources is mediated through the production of a broad range of enzymes, the production of which is tightly controlled by a network of regulators and linked to the activation of catabolic pathways to convert the released monomers. This review summarizes the knowledge of Aspergillus regulators involved in plant biomass utilization.
