“…The disease has four aetiological agents of the genus Stemphylium (Pleosporales, Dothideomycetes: Ascomycota; Videira et al., 2017) that establish pathogenic, saprotrophic or endophytic relationships with many plant species (Jones, Zitter, et al., 2014). Based on nourishment and host range, Stemphylium species can be considered polyphagous necrotrophs (de Souza et al., 2018). Among them, S .…”

Tomato grey leaf spot is a fungal disease that provokes losses in tomato yield. The aim of this work is to analyse genomic differences among three isolates of Stemphylium lycopersici that differ in virulence and sporulation. The bioinformatics analysis led us to predict the identity of putative effectors, pathogenesis and virulence factors. Like the genome of other necrotrophic pathogens, Stemphylium encodes a wide spectrum of effectors, including an ample and diverse array of carbohydrate‐degrading enzymes. Interestingly, the number of predicted effectors was unrelated to virulence. Low virulence appeared to be associated with the presence of several double‐stranded RNAs from viruses as well as cellular processes related to protein degradation, redox and detoxifying processes and monoterpenes production. This is the first identification of the potential effectors of tomato–S. lycopersici interaction; nonetheless functional studies should be done.
