Alternaria panax is a fungal plant pathogen, which causes Alternaria blight of ginseng. [2]
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels.
Ginseng is the root of plants in the genus Panax, such as Korean ginseng (P. ginseng), South China ginseng (P. notoginseng), and American ginseng (P. quinquefolius), characterized by the presence of ginsenosides and gintonin. Ginseng is common in the cuisines and medicines of China and Korea.
The Panax (ginseng) genus belongs to the Araliaceae (ivy) family. Panax species are characterized by the presence of ginsenosides and gintonin. Panax is one of approximately 60 plant genera with a classical disjunct east Asian and east North American distribution. Furthermore, this disjunct distribution is asymmetric as only two of the ~18 species in genus are native to North America.
Panax ginseng, ginseng, also known as Asian ginseng, Chinese ginseng or Korean ginseng, is a species of plant whose root is the original source of ginseng. It is a perennial plant that grows in the mountains of East Asia.
Withania somnifera, known commonly as ashwagandha or winter cherry, is an evergreen shrub in the Solanaceae or nightshade family that grows in India, the Middle East, and parts of Africa. Several other species in the genus Withania are morphologically similar.
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.
Aralioideae is a subfamily of flowering plants contains around 50 recognized genera. These include the genus Panax, to which ginseng belongs. Other notable species are the Angelica-tree, the devil's club, or common ivy.
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 dauci is a plant pathogen. The English name of the disease it incites is "carrot leaf blight".
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 radicina is a fungal plant pathogen infecting carrots.
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 helianthi is a fungal plant pathogen causing a disease in sunflowers known as Alternaria blight of sunflower.
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.
American ginseng is a species of flowering plant in the ivy family Araliaceae. It is native to eastern North America and introduced in China. Europeans discovered American ginseng near Montreal in 1716. It has been wild-harvested and exported to Asia since 1720. As of January 2024, its conservation status is globally vulnerable. In Canada, the species is endangered.
Panax trifolius, commonly called dwarf ginseng, is a plant native to the Northeastern and Appalachian regions of North America. It is found in low mesic woods with acidic soils.
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.
