Alternaria is a genus of Deuteromycetes fungi. All species are known as major plant pathogens. They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma. They are present in the human mycobiome and readily cause opportunistic infections in immunocompromised people such as AIDS patients.
Alternaria alternata is a fungus causing leaf spots, rots, and blights on many plant parts, and other diseases. It is an opportunistic pathogen on over 380 host species of plant.
Alternaria brassicae is a plant pathogen able to infect most Brassica species including important crops such as broccoli, cabbage and oil seed rape. It causes damping off if infection occurs in younger plants and less severe leaf spot symptoms on infections of older plants.
Alternaria japonica is a fungal plant pathogen. It is a cause of black spot disease in cruciferous plants. It is not a major source of crop loss, but is considered dangerous for plants during the seedling stage.
Alternaria raphani is a fungal plant pathogen.
Alternaria citri is a fungal plant pathogen that causes black rot in citrus plants.
Alternaria euphorbiicola is a fungal plant pathogen.
Alternaria helianthicola is a fungal plant pathogen.
Alternaria limicola is a plant pathogen affecting citruses. It is the cause of the Mancha foliar de los citricos disease.
Alternaria linicola is a fungal plant pathogen, that affects linseed plants.
Alternaria padwickii is a plant pathogen that attacks rice. It is associated with the disease stackburn, otherwise known as alternaria leaf spot.
Alternaria radicina is a fungal plant pathogen infecting carrots.
Alternaria senecionis is a fungal plant pathogen, can cause leaf spot on Cineraria species, such as on Senecio cruentus in Denmark.
Alternaria solani is a fungal pathogen that produces a disease in tomato and potato plants called early blight. The pathogen produces distinctive "bullseye" patterned leaf spots and can also cause stem lesions and fruit rot on tomato and tuber blight on potato. Despite the name "early," foliar symptoms usually occur on older leaves. If uncontrolled, early blight can cause significant yield reductions. Primary methods of controlling this disease include preventing long periods of wetness on leaf surfaces and applying fungicides. Early blight can also be caused by Alternaria tomatophila, which is more virulent on stems and leaves of tomato plants than Alternaria solani.
Alternaria zinniae is a fungal plant pathogen.
Alternaria saponariae is a fungal plant pathogen.
Alternaria panax is a fungal plant pathogen, which causes Alternaria blight of ginseng.
Ulocladium is a genus of fungi. Species of this genus contain both plant pathogens and food spoilage agents. Other species contain enzymes that are biological control agents. Some members of the genus can invade homes and are a sign of moisture because the mold requires water to thrive. They can cause plant diseases or hay fever and more serious infections in immuno-suppressed individuals.
Alternaria tenuissima is a saprophytic fungus and opportunistic plant pathogen. It is cosmopolitan in distribution, and can colonize a wide range of plant hosts. Colonies of A. tenuissima produce chains on agar growth media. The fungus often forms concentric ring patterns on infected plant leaves. This species produces the allergen Alt a 1, one of the most important outdoor seasonal fungal allergens associated with allergy and asthma provocation. In rare circumstances, this species is also known to infect immunosuppressed humans and animals.
Radicinin is a phytotoxin with the molecular formula C12H12O5. Radicinin is produced by the fungal plant pathogen Alternaria radicina and other Alternaria species.
