Cercospora Kikuchii
''Cercospora kikuchii'' is a fungal plant pathogen that affects 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, which has numerous uses. Traditional unfermented food uses of soybeans include soy milk, from which tofu a ...s. It results in both the Cercospora leaf blight and purple seed stain diseases on soybean and is found almost worldwide. ''C. kikuchii'' produces the toxin cercosporin, as do a number of other ''Cercospora'' species. Symptoms Seed: The disease on the host soybean itself can be determined by a light activated red perlene quinon, cercosporin, with a molecular weight of 534. Purple seed stain by Cercospora can be determined by a variety of factors. First, infected seeds have spots that are usually pink or purple. The size can be from minuscule to covering the whole seed (Li 2019). The coloration will be from the hilum area. Germination and seedling size may be ...

Fungus
A fungus ( : fungi 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 a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cercospora Leaf Blight (CLB) 5
''Cercospora'' is a genus of ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus ''Mycosphaerella''. Most species of this genus cause plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known of the species. Selected species *''Cercospora acetosella'' - found on sheep sorrel and other docks *''Cercospora aciculina'' *''Cercospora agerati'' *''Cercospora alabemensis'' *''Cercospora alismatis'' *''Cercospora althaeina'' *''Cercospora angreci'' - causes leaf spot of orchids *''Cercospora angulata'' *'' Cercospora apii'' - causes leaf spot on celery, and found on other plants, including ''Impatiens'' * ''Cercospora apii'' f.sp. ''clerodendri'' *'' Cercospora apiicola'' - causes leaf spot on celery *'' Cercospora arachidicola'' - causes peanut leaf spot *''Cercospora arctii'' *''Cercos ...
