Importance and distribution
Wilsonomyces is a pathogenic genus of quarantine significance since it infects wide range of stone fruit trees such as cherry and peach foliage (Grove 2002). Wilsonomyces carpophilus causes shot hole disease of stone fruit trees (Ye et al. 2020).
Biochemical importance of the genus, chemical diversity or applications
Wilsonomyces has been reported to produce two metabolites -oxa-7-azaspiro [4.4] non-2- ene-4,6-dione core and pseurotin A3. (Narmani et al. 2018).
Wilsonomyces comprises only one species, W. carpophilus infecting Amygdalus scoparia in Asia (Iran) and Prunus species in Asia (Iran) and Oceania (Australia, New Zealand).
