Unique patterns of mating pheromone presence and absence could result in the ambiguous sexual behaviors of Colletotrichum species.

ABSTRACT: Colletotrichum species are known to engage in unique sexual behaviors that differ significantly from the mating strategies of other filamentous ascomycete species. For example, most ascomycete fungi require the expression of both the MAT1-1-1 and MAT1-2-1 genes to induce sexual reproduction. In contrast, all isolates of Colletotrichum harbor only the MAT1-2-1 gene and yet, are capable of recognizing suitable mating partners and producing sexual progeny. The molecular mechanisms contributing to mating types and behaviors in Colletotrichum are, however, unknown. A comparative genomics approach analyzing 35 genomes, representing 31 Colletotrichum species and two Verticillium species, was used to elucidate a putative molecular mechanism underlying the unique sexual behaviors observed in Collet
