ANNOUNCEMENT Plant biomass is a major resource for the sustainable circular economy, and fungi have an important role in its biorefinery (1). With an increasing number of fungal genome sequences available and automatic annotation of their carbohydrate-active enzymes (2) on the JGI Mycocosm portal (3), it is becoming easier to do genome-based comparison of the potential of fungal species for plant biomass valorization.

3. Results 3.1. Genomic Potential of PBD CAZymes Shows Diversity across Six Fungi In total, the genome repertoire of 65 CAZy (sub-)families and feruloyl esterases (FAEs) involved in degradation of plant polysaccharides was comparatively analyzed in six fungi (Figure 1 and Figure S1).

A genome-wide phylogenetic analysis was conducted to determine the relationship between the newly sequenced genomes and other related species present in MycoCosm. This resulted in a highly supported phylogram providing insights into taxonomic relationships within Aspergillus and between Aspergillus and related genera. With the introduction of the single name nomenclature for fungal anamorph and teleomorph forms, there is discussion over whether to split Aspergillus or to maintain the genus as one.
