Innate Immune Responses in the Alternaria-Dendritic Cell Interaction
Exposure to spores and hyphae of Alternaria alternata, an airborne ubiquitous fungus, is clinically associated with allergic airway disorders including allergic rhinitis, asthma, and chronic rhinosinusitis. Dendritic cells are known as the type of antigen presenting cells most often associated with …

Characterization of Alternaria alternata isolates causing brown spot of potatoes in South Africa
Alternaria alternata (Fr.) Keissler is now widely recognized as the causal agent of brown spot and black pit of potatoes. Brown spot is a foliar disease with potential to cause 30% yield loss and postharvest losses of up to 10%. Losses are mainly due to premature defoliation. In this study, …

Alternaria Leaf Blight and Head Rot of Broccoli: UAV-Based Disease Detection and Fungicide Resistance Management
Alternaria leaf blight and head rot (ABHR) of brassicas significantly impacts yield, threatening the sustainability of the broccoli industry. Management traditionally relies on quinone outside inhibitor (QoI) fungicides, but recent reports indicate reduced efficacy. The causes for this decline are …
