Mycosphaerella Vulgaris
''Mycosphaerella'' is a genus of ascomycota. With more than 10,000 species, it is the largest genus of plant pathogen Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomyc ... fungi. The following introduction about the fungal genus ''Mycosphaerella'' is copied (with permission) from the dissertation of W. Quaedvlieg (named: Re-evaluating ''Mycosphaerella'' and allied genera). Species belonging to the fungal genus ''Mycosphaerella'' (1884) (''Capnodiales'', ''Dothideomycetes'') have evolved as endophytes, saprotrophs and symbionts, but mostly ''Mycosphaerella'' species are foliicolous plant pathogens which are the cause of significant economical losses in both temperate and tropical crops worldwide. The generic concept of Mycosphaerella is based on the type species of the genus, ''M. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycosphaerella Fragariae
Common spot of strawberry is one of the most common and widespread diseases afflicting the strawberry. Common spot of strawberry is caused by the fungus ''Mycosphaerella fragariae'' (imperfect stage is ''Ramularia tulasnei''). Symptoms of this disease first appear as circular, dark purple spots on the leaf surface. ''Mycosphaerella fragariae'' is very host-specific and only infects strawberry. Hosts and symptoms This disease affects strawberry plant foliage causing purple spots ⅛ to ¼ inches across on the upper side of the leaves. At first, the whole spot is purple but as the disease matures the center of the leaf spots on older leaves become tan or gray, then almost white. Lesions on younger leaves remain light brown. When numerous spots merge foliage death can occur; this can stunt or kill infected plants when severe. On petioles, stolons, calyxes, and fruit trusses, elongated lesions may form and interfere with water transport in the plant, weakening the plant and makin ...

Mycosphaerella Cruenta
''Mycosphaerella cruenta'', also called ''Pseudocercosopora cruenta'' in its asexual stage, is a fungal plant pathogen belonging to the group Ascomycota. It can affect several legume plants, including species of ''Phaseolus, Vigna, Calopogonium, Lablab niger, Mucuna'' and ''Stizolobium deeringianum ucuna pruriens.html" ;"title="">[2/nowiki>">">[2/nowiki> It causes cowpea cercospora leaf spot, one of the most widespread and significant plant diseases in Africa and Asia. A city in China reported a 100% ''Mycosphaerella cruenta'' infection rate on cowpea in 2014[5]. In Africa, an epidemic can cause a yield loss of up to 40% Symptoms and signs Cercospora leaf spots of cowpea begin as small, lighter coloured areas, almost yellow. Later they become bronze to dark grey, roughly circular to more elongated and up to 10 mm across There will be chlorotic spots on upper surfaces of leaves, masses of spores on lesions which resemble black mats on lower leaf surface, and necrotic spots ...

HOSTS: On leaves, stems and peduncles of ''Linum usitatissimum, and Linum'' spp. DISEASE: Pasmo disease of flax GEOGRAPHICAL DISTRIBUTION: Widespread with host (CMI Map 18, ed. 5, 1977). TRANSMISSION: The fungus carries over on crop debris and other ''Linum'' spp. It is said to remain viable in soil for several years (60, 2047). Infested seeds on germination produce infected seedlings (5, 365; 25, 449).

Mycosphaerella Henningsii
''Mycosphaerella henningsii'' is a fungal plant pathogen that causes Brown leaf spot (BLS) in cassava).Part It is one of the worst fungal diseases of cassava. BLS disease appears as small brown spots with dark borders on the upper leaf surface. The brown spots form between leaf veins so their size and shape are limited by the veins. The centre of the brown spots may fall out leaving a hole in the leaf. During a bad attack the infected leaves become yellow and dry, and may die early. The disease can greatly reduce yields. The fungus lives in diseased cassava leaves on the plant or those on the ground. It spreads to new leaves and plants by wind or rain splash.

Mycosphaerella Graminicola
''Zymoseptoria tritici'', synonyms ''Septoria tritici'', ''Mycosphaerella graminicola'', is a species of filamentous fungus, an ascomycete in the family ''Mycosphaerellaceae''. It is a wheat plant pathogen causing septoria leaf blotch that is difficult to control due to resistance to multiple fungicides. The pathogen today causes one of the most important diseases of wheat. In 2011, Quaedvlieg et al. introduced a new combination for this species: ''Zymoseptoria tritici'' (Desm.) Quaedvlieg & Crous, 2011, as they found that the type strains of both the genus ''Mycosphaerella'' (linked to the anamorph genus ''Ramularia'') and the genus ''Septoria'' (linked to the genus ''Septoria'', an extensive clade of very distinct septoria-like species within the ''Mycosphaerellaceae'') clustered separately from the clade containing both ''Zymoseptoria tritici'' and ''Z. passerinii''. Since 2011, a total of eight ''Zymoseptoria'' species have been described within the genus ''Zymoseptoria''; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
