Fungal Plant Pathogens And Diseases
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'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oidium (genus)
''Oidium'' is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example: *''Oidium alphitoides'' (= ''O. quercinum'') = '' Microsphaera alphitoides'' (on oaks) *''Oidium anacardii'' (= ''Acrosporium anacardii'') (on cashew) *'' Oidium arachidis'' (on peanut) *''Oidium asteris-punicei'' (= ''Erysiphe cichoracearum'') (on mangos) *''Oidium balsamii'' = '' Erysiphe verbasci'' (on mulleins) *''Oidium begoniae'' (=''O.cyclaminis'', ''O.lini'', ''O.violae'') = ''Erysiphe polyphaga'' (on '' Valerianella'', ''Calluna'' and ''Erica'') *''Oidium candicans'' (= ''Monilia candicans'') *''Oidium caricae'' (on papayas) *'' Oidium caricae-papayae'' (on papayas) *''Oidium caricicola'' (on papayas) *''Oidium chrysanthemi'' = ''Erysiphe cichoracearum'' (on numerous plant species, especially Asteraceae) *''Oidium carpini'' *'' Oidium chartarum'' (= ''Torula chartarum'') ...
