Erysiphe Alphitoides
''Erysiphe alphitoides'' is a species of fungus which causes powdery mildew on oak trees. Discovery and taxonomy Today oak powdery mildew is one of the most common diseases in European forests but it is thought to not always have been present in these forests. The first reports of the disease were made in Paris and other regions of France, Spain, Luxembourg and the Netherlands in 1907. By 1908 the disease had spread into many other European countries, becoming an epidemic. By 1909 it had reached Russia and Turkey, followed by Brazil in 1912 and soon after was distributed around the world. The sudden outbreak of the disease puzzled mycologists as they were unsure about the origin of the pathogen. Its anamorph was easily distinguished from '' Phyllactinia guttata'' which had previously been reported to cause powdery mildew on oaks in Europe at low intensity. It did however share morphological similarities with '' Oïdium quercinum'', '' Calocladia penicillata'' and '' Microsphaer ...

Erysiphe Diffusa
''Microsphaera diffusa'' is a plant pathogen that is known to cause powdery mildew on soybean The soybean, soy bean, or soya bean (''Glycine max'') is a species of legume native to East Asia, widely grown for its edible bean. Soy is a staple crop, the world's most grown legume, and an important animal feed. Soy is a key source o ...s. Importance Powdery mildew is a significant pathogen of soybeans and tends to cause epidemics about every 10–15 years in Wisconsin. The first epidemic there was observed in 1975 and several have occurred since. When 82% of the soybean leaf area is covered by ''M. diffusa'', photosynthetic and transpiration rates are less than half of normal soybeans, thus affecting soybean yield. Different studies have found varying amounts of yield reduction due to powdery mildew. In Illinois, measured yield losses ranged up to 14 percent. Studies from Iowa recorded yield losses of up to an estimated 10 bushels per acre. In Wisconsin, yield loss w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leotiomycetes Genera
The Leotiomycetes are a class of ascomycete fungi. Many of them cause serious plant diseases. Systematics The class Leotiomycetes contains numerous species with an anamorph placed within the '' fungi imperfecti'' (deuteromycota), that have only recently found their place in the phylogenetic system. The older classifications placed Leotiomycetes into the Discomycetes clade ( inoperculate Discomycetes). Molecular studies have recently shed some new light to the still obscure systematics. Most scholars consider Leotiomycetes a sister taxon to Sordariomycetes in the phylogenetic tree of Pezizomycotina. Its division into subclasses have received strong support by the molecular data, but the overall monophyly of Leotiomycetes is dubious. The order Lichinodiales and family '' Lichinodiaceae'', newly circumscribed in 2019 to contain the genus cyanolichen genus '' Lichinodium'', is the first known group of lichen-forming fungi in the Leotiomycetes. Family ''Lichinodiaceae'' was then pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungal Plant Pathogens And Diseases
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ' ...

Erysiphe Syringae
Powdery mildew of lilac, or ''Erysiphe syringae'' (formerly ''Microsphaera syringae'') is a fungal pathogen of lilacs. Importance The host of the fungal pathogen, ''Syringa vulgaris'' or the common lilac, is an ancient plant with significance in horticultural activities and wild roots in eastern Europe. Its Latin epithet, vulgaris, translates into ‘common’ in English, and was popularized by the pioneer taxonomist Carl von Linné. One of the first dutiful observations of the pathogen, ''E. syringae'', was made in a journal of the German Botanical Society, Berichte der Deutschen Botanische Gesellschaft, where it was observed as a powdery mildew pathogen unique to lilacs referencing the physical characteristics of its ascocarp appendages. The pathogen contributes to a deathly and diseased look. Common lilac is known for its spring flowers, which can be altered due to decay of flowering stems after intense infection.

Erysiphe Polygoni
''Erysiphe betae'' is a fungal plant pathogen. It is a form of powdery mildew that can affect crops of sugar beet A sugar beet is a plant whose root contains a high concentration of sucrose and that is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with ..., that could cause up to a 30% yield loss. The fungus occurs worldwide in all regions where sugar beet is grown and it also infects other edible crops, e.g. beetroot. Identification This pathogen is a strict obligated parasite, and therefore can only be identified when ''in planta''. Often to properly identify this pathogen, some form of microscopic analysis is needed when it is only found on one type of plant. This can be done through isolation and observation of cleistothecia, which are the product of sexual reproduction.

Erysiphe Heraclei
''Erysiphe heraclei'' is a plant pathogen that causes powdery mildew on several species including dill, carrot and parsley. History It was originally found in 1815, on the leaves of a species of ''Heracleum (plant), Heracleum'' in France. It was found in Australia in New South Wales in 2007 then it spread to Tasmania and South Australia in 2008. Importance ''Erysiphe heraclei'' is no different than your typical powdery mildew as it shares many of the important traits that make it a plant disease worth paying attention too. In the case of powdery mildew of carrots yield loss is a very typical result of an infection, as well as the reduction of the ability to mechanically pull carrots from the ground during harvest due to leaf damage."Vegetable Diseases Cornell", vegetablemdonline.ppath.cornell.edu, 2018, http://vegetablemdonline.ppath.cornell.edu/NewsArticles/Carrot_Powdery.html.
