Abstract Background: Colletotrichum species are known to engage in unique sexual behaviours that differ significantly from the mating strategies of other filamentous ascomycete species. Most ascomycete fungi require the expression of both the MAT1-1-1 and MAT1-2-1 genes to regulate mating type and induce sexual reproduction. In contrast, all isolates of Colletotrichum are known to harbour 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 behaviours in Colletotrichum are thus unknown. Results: A comparative genomics approach analysing genomes from 47 Colletotrichum isolates was used to elucidate a putative molecular mechanism underlying the unique sexual behaviours observed in Colletotrichum species. The existence of only the MAT1-2 idiomorph was confirmed across all species included in this study. Comparisons at the loci harbouring the two mating pheromones and their cognate receptors revealed interesting patterns of gene presence and absence as well as gene loss. The results also showed that these genes have been lost multiple times over the evolutionary history of this genus. Conclusion: The multiple losses of the pheromone genes in these species suggest strong selection against the typical mating strategies seen in other species. This further suggests that these pheromones no longer play a role in mating type determination and that the species of this genus have undiscovered mechanisms by which to control mating type and mating partner recognition. This research thus provides a base from which further interrogation of this topic can take place.

In Vitro Antifungal Activity

Antifungal proteins (AFPs) from ascomycete fungi could help the development of antimycotics. However, little is known about their biological role or functional interactions with other fungal biomolecules. We previously reported that AfpB from the postharvest pathogen Penicillium digitatum cannot be detected in the parental fungus yet is abundantly produced biotechnologically. While aiming to detect AfpB, we identified a conserved and novel small Secreted Cysteine-rich Anionic (Sca) protein, encoded by the gene PDIG_23520 from P. digitatum CECT 20796. The sca gene is expressed during culture and early during citrus fruit infection. Both null mutant (Δsca) and Sca overproducer (Scaop) strains show no phenotypic differences from the wild type. Sca is not antimicrobial but potentiates P. digitatum growth when added in high amounts and enhances the in vitro antifungal activity of AfpB. The Scaop strain shows increased incidence of infection in citrus fruit, similar to the addition of purified Sca to the wild-type inoculum. Sca compensates and overcomes the protective effect of AfpB and the antifungal protein PeAfpA from the apple pathogen Penicillium expansum in fruit inoculations. Our study shows that Sca is a novel protein that enhances the growth and virulence of its parental fungus and modulates the activity of AFPs.
