Sac fungiAlternaria / PhylumAscomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. Wikipedia

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).

What kind of organism is Alternaria solani?

plant pathogen
Alternaria solani is a plant pathogen and the causative agent of early blight in solanum species. It produces numerous polyketides such as solanapyrone A (50) and alternaric acid (51), and is thus an ideal target species for speculative PKS gene-fishing expeditions (Figure 4).

What is Alternaria in biology?

Alternaria is a genus of Deuteromycetes fungi. Alternaria 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.

Which type of spores are reported in Alternaria?

Spores of Alternaria can be formed singly, but most often in chains. They are typically club-shaped and are highly septate, having divisions in both vertical and horizontal directions. The spore surfaces are usually smooth, but may have small rounded warts creating a slightly rough surface.

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}.

What is the morphological structure of Alternaria pathogen?

The taxonomy of Alternaria has been based on morphological characteristics such as conidia dimension, color, and septa (longitudinal and transverse); wall ornamentation; beak type and size; conidiophore type, size, and septa; sporulation patterns (in chains or solitary; branched or unbranched); and cultural …

What causes Alternaria?

Alternaria is potentially caused by three pathogens: Alternaria brassicicola, A. brassicae, and A. raphani. Based on initial screenings, the primary species causing disease in Minnesota broccoli is Alternaria brassicicola.

Is Alternaria solani is soil borne disease?

andigena and S. endobioticum are soil-borne pathogens and the other species are airborne. A minority of eight (24%) of the described species is airborne. Of these, five species inflict great actual (Alternaria solani and Phytophthora infestans) or potential (P.

Which of the following disease is caused by Alternaria solani *?

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.

Where is Alternaria 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.
