Mucor species belong to the Mucorales order within the Mucoromycota phylum, an early diverging fungal lineage. Although Mucor species are often ubiquitous some species have been reported to specifically occur in certain ecological niches. In this study, similarities and differences of a representative set of Mucor species with contrasted lifestyles were investigated at the transcriptome level. Five strains pertaining to five different species were studied, namely M. fuscus and M. lanceolatus, two species used in cheese production (during ripening), M. racemosus, a recurrent cheese spoiler sometimes described as an opportunistic pathogen, M. circinelloides, often described as an opportunistic pathogen and M. endophyticus, a plant endophyte. A core transcriptome was delimited and a phylogenetic analysis led to an altered phylogenetic placement of M. endophyticus compared to previously published topologies. Interestingly, the core transcriptome comprising 5566 orthogroups included genes potentially involved in secondary metabolism. As expected, given the wide taxonomic range investigated, the five transcriptomes also displayed specificities that can be, for some of them, linked to the different lifestyles such as differences in the composition of transcripts identified as virulence factors or carbohydrate transporters.
