    Abstract:
    Sclerotinia sclerotiorum (Lib.) is a necrotrophic plant pathogen that is capable of infecting more than 400 plant species worldwide. The sclerotium plays important roles in the disease and fungal life cycles. The exudation of liquid droplets is a common feature during sclerotial development, but little is known regarding the nature of these exudates. A proteome-level study was performed in order to gain a better understanding of the types of proteins present in the exudates. Fifty-six proteins were identified and classified into several functional categories, including amino acid metabolism, carbohydrate metabolism, lipid and secondary metabolism, as well as energy, signal transduction, and those with unknown functions. The roles of the identified proteins are discussed within the context of sclerotial development and fungal virulence. Our results may facilitate additional studies aimed at characterizing the function of these proteins in the formation of sclerotia and the life cycle of S. sclerotiorum.
