Breve descrizione dei contenuti:
Background: Pyrenochaeta lycopersici is a soil-dwelling ascomycete pathogen that causes corky root rot disease in
tomato (Solanum lycopersicum) and other Solanaceous crops, reducing fruit yields by up to 75%. Fungal pathogens
that infect roots receive less attention than those infecting the aerial parts of crops despite their significant impact
on plant growth and fruit production.
Results: We assembled a 54.9Mb P. lycopersici draft genome sequence based on Illumina short reads, and
annotated approximately 17,000 genes. The P. lycopersici genome is closely related to hemibiotrophs and
necrotrophs, in agreement with the phenotypic characteristics of the fungus and its lifestyle. Several gene families
related to host–pathogen interactions are strongly represented, including those responsible for nutrient absorption,
the detoxification of fungicides and plant cell wall degradation, the latter confirming that much of the genome is
devoted to the pathogenic activity of the fungus. We did not find a MAT gene, which is consistent with the
classification of P. lycopersici as an imperfect fungus, but we observed a significant expansion of the gene families
associated with heterokaryon incompatibility (HI).
Conclusions: The P. lycopersici draft genome sequence provided insight into the molecular and genetic basis of the
fungal lifestyle, characterizing previously unknown pathogenic behaviors and defining strategies that allow this
asexual fungus to increase genetic diversity and to acquire new pathogenic traits.
