Botryosphaeria Dothidea
''Botryosphaeria dothidea'' is a plant pathogen that causes the formation of cankers on a wide variety of tree and shrub species. It has been reported on several hundred plant hosts and on all continents except Antarctica.Crous, P.W., B. Slippers, M.J. Wingfield, J. Rheeder, W.F.O. Marasas, A.J.L. Philips, A. Alves, T. Burgess, P. Barber, and J.Z. Groenwald. 2006. Phylogenetic lineages in the Botryosphaeriaceae. Studies in Mycology 55:235-253.Farr, D.F., and A.Y. Rossman. Fungal Databases, Systematic Mycology and Microbiology Laboratory, ARS, USDA. Accessed 21 November 21, 2013. ''B. dothidea'' was redefined in 2004, and some reports of its host range from prior to that time likely include species that have since been placed in another genus.Phillips, A.J.L., A. Alves, J. Abdollahzadeh, B. Slippers, M.J. Wingfield, J.Z. Groenewald, and P.W. Crous. 2013. The Botryosphaeriaceae: Genera and species known from culture. Studies in Mycology 76:51-167. Even so, ''B. dothidea'' has sin ...

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, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated popula ...

Cankers
A plant canker is a small area of dead tissue, which grows slowly, often over years. Some cankers are of only minor consequence, but others are ultimately lethal and therefore can have major economic implications for agriculture and horticulture. Their causes include a wide range of organisms as fungi, bacteria, mycoplasmas and viruses. The majority of canker-causing organisms are bound to a unique host species or genus, but a few will attack other plants. Weather and animals can spread canker, thereby endangering areas that have only slight amount of canker. Although fungicides or bactericides can treat some cankers, often the only available treatment is to destroy the infected plant to contain the disease. Examples * Apple canker, caused by the fungus ''Neonectria galligena'' * Ash bacterial canker, now understood to be caused by the bacterium '' Pseudomonas savastanoi'', rather than ''Pseudomonas syringae''. After DNA-relatedness studies ''Pseudomonas savastanoi'' has be ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ...

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'' (''true ...

Grapevine Trunk Diseases
Grapevine trunk diseases (GTD) are the most destructive diseases of vineyards worldwide. Fungicides (such as sodium arsenite or 8-hydroxyquinoline, used to fight esca) with the potential to control GTD have been banned in Europe and there are no highly effective treatments available. Action to develop new strategies to fight these diseases are needed. The following fungal species are responsible for grapevine trunk diseases: * '' Botryosphaeria dothidea'' and other ''Botryosphaeria'' species, such as '' B. obtusa'', '' B. parva'' and '' B. australis'',Botryosphaeria spp. as grapevine trunk disease pathogens.

Crous, Phytopathologia Mediterranea, 2006, volume 45, pages 43-54 * ''Cylindrocarpon'' spp., ''Ilyonectria'' spp., ''Dactylonectria'' spp. and ''Campylocarpon'' spp.Occurrence of grapevine trunk disease pathogens in rootstock mother plants in South Africa.

Fungi Described In 1823
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms.
