Alternaria is a genus of filamentous fungi that includes many species known to be common airborne allergens and plant pathogens. Research in the field of alternaria typically focuses on understanding the biology, ecology, and pathogenicity of these fungi, as well as developing strategies for controlling their impact on human health and agriculture. Studies may involve investigating the genetic diversity of alternaria species, their mechanisms of pathogenicity, and their interactions with host plants or the human immune system. Additionally, researchers may explore methods for preventing or managing alternaria-related diseases in plants or improving diagnostic tools for detecting alternaria allergens in the environment.
