Sclerotinia sclerotiorum is one of the most notorious and ubiquitous soilborne plant pathogens, causing serious economic losses to a large number of hosts worldwide. Although virulence factors have been identified in this filamentous fungus, including various cell-wall-degrading enzymes, toxins, oxalic acids and effectors, our understanding of its virulence strategies is far from complete. To explore novel factors contributing to disease, a new pipeline combining forward genetic screening and next-generation sequencing was utilized in this study. Analysis of a hypovirulent mutant revealed that a mutation in an amidase-encoding gene, Sscle_10g079050, resulted in reduced virulence. This is a first report on the contribution of an amidase to fungal virulence, likely through affecting oxalic acid homeostasis. [ABSTRACT FROM AUTHOR]
