Classification of alternaria
What is the classification of Alternaria alternata?
The Pleosporales is the largest order in the fungal class Dothideomycetes. By a 2008 estimate it contains 23 families, 332 genera and more than 4700 species.
What is the common name for Alternaria?
Alternaria alternata (Black Rot, Black Spot)
How do you identify Alternaria?
The identification of Alternaria species requires a combination of morphological features and molecular methods. Morphological features such as conidial shape, size of primary conidium, conidial branching arrangement and primary conidiosphore length were used in the identification by Simmons and Roberts (1993).
Is Alternaria a Ascomycetes?
Alternaria is a large genus that belongs to phylum Ascomycota (Sac fungi). A majority of Alternaria species are saprobic, which means that they are largely involved in the decomposition of various organic matter.
Which disease is caused by Alternaria?
(A) Leaf spot disease caused by Alternaria crassa on jimson weed.
Is Alternaria Ascomycetes or deuteromycetes?
Alternaria is a genus of Deuteromycetes fungi.
Is Alternaria a sac fungi?
Alternaria alternata is a fungus which has been recorded causing leaf spot and other diseases on over 380 host species of plant.
What is the class of Penicillium?
Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life.
What is the class of Aspergillus?
Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life.
What is Alternaria Alternata in humans?
Alternaria is an ubiquitous fungus that is considered to be a nonpathogenic contaminant of the clinical specimen unless isolated by repeated culture and correlated with clinical findings. However, it is a rare cause of human infection, especially in immunocompromised patients but even more rarely in healthy hosts [1].
Is Alternaria harmful to humans?
Alternaria, a phytotoxins have toxic effect in humans and animals.
What is the scientific name of Fusarium?
What does Alternaria do to plants?
Alternaria alternata is a fungus which has been recorded causing leaf spot and other diseases on over 380 host species of plant. It is an opportunistic pathogen on numerous hosts causing leaf spots, rots and blights on many plant parts.
Where is Alternaria found?
Alternaria alternata is a ubiquitous saprophyte that is found in the soil and on plants, especially on decaying vegetation. Therefore, Alternaria antigen levels likely reflect the abundance of local vegetation.
Where is Alternaria fungi found?
Alternaria is often found in soil and on mediums such as plants, cereal grains, grass, corn silage, rotten wood, bricks, canvas, iron, compost, and bird nests.
What is Alternaria allergy?
alternata spores is associated with upper and lower respiratory hypersensitivity, mainly asthma and allergic fungal rhinosinusitis. Allergic bronchopulmonary mycosis and hypersensitivity pneumonitis may also develop. Allergens of A. alternata are found in both conidia and mycelia.
Is Alternaria a pathogen?
Alternaria alternata is a common species of fungus frequently isolated from plants as both an endophyte and a pathogen.
Is Alternaria a parasite?
The observation that saprobic Alternaria species can become parasitic when they meet a weakened host illustrates that the distinction between saprophytic and parasitic behaviour is not always evident. Despite the taxonomic and pathogenic differences between Alternaria species, they cause similar infection patterns.
What color is Alternaria mold?
Alternaria in the home ranges from olive green to brown/gray/black and often has a velvety appearance, sometimes with longer hair-like growth. There are approximately 40 species of Alternaria, but many of them are found on leaves, trees, bushes, or other outdoor vegetation.
What is habitat of Alternaria?
Habitat/Ecology. Alternaria spp. are cosmopolitan dematiaceous fungi commonly isolated from plants, soil, food and indoor air environment. Alternaria species are known as major plant pathogens {1635; 725} and saprophytes on many substrates {816; 1056; 3729; 725}.
How do Alternaria reproduce?
Alternaria dianthi reproduces asexually, forming row-like spores off of hyphae. Spores are formed on blisters on the host as well as within the mycelium. The thin, globular spores are spread through water. Spore production and infection decreases over winter, and has been observed to be highest in rainy summer months.
