Genome-Wide Associations within Diverse Wild Apple Germplasm for Postharvest Blue Mold Resistance to <i>Penicillium expansum</i> Open
Post-harvest disease caused by the blue mold fungus, Penicillium expansum , accounts for a substantial proportion of economic losses in United States apple industry. Multiple modes of entry in the apple supply chain, plus emerging fungicid…

UVC (254 nm) and Far UVC (222 nm) Irradiation Affects In Vitro Growth of <i>Colletotrichum</i> sp. Isolates and Their Infection of Detached Strawberry Leaves Open
Conventional ultraviolet C at 254 nm (UVC) and Far UVC at 222 nm (Far UVC) were evaluated as alternatives to fungicides for disease control. Conidia of 13 isolates of strawberry anthracnose pathogens (five Colletotrichum species in two com…

Exposure in vitro to an Environmentally Isolated Strain TC09 of Cladosporium sphaerospermum Triggers Plant Growth Promotion, Early Flowering, and Fruit Yield Increase Open
A growing number of bacteria and fungi have been found to promote plant growth through mutualistic interactions involving elements such as volatile organic compounds (VOCs). Here, we report the identification of an environmentally isolated…
