Dickeya Zeae
''Dickeya'' is a genus of the family Pectobacteriaceae that consists mainly of pathogens from herbaceous plants. Dickeya is the result of the reclassification of 75 strains of ''Pectobacterium chrysanthemi'', as well as '' Brenneria paradisiaca'' CFBP 4178, into a new genus. The genus is named for American phytopathologist Robert S. Dickey. Several species in this genus, such as ''Dickeya dadantii'', are known phytopathogens. Species now placed here include: * '' Dickeya aquatica'' * '' Dickeya chrysanthemi'' * '' Dickeya dadantii'' (''D. chrysanthemi'') * '' Dickeya dianthicola'' * '' Dickeya dieffenbachiae'' * '' Dickeya paradisiaca'' * ''Dickeya solani ''Dickeya solani'' is a bacterium that causes blackleg and soft rot in potato crops.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Dickeya Solani
''Dickeya solani'' is a bacterium that causes blackleg and soft rot in potato crops. Its symptoms are often indistinguishable from those caused by '' Pectobacterium'' but is more virulent, causing disease from lower levels of inoculum and spreading through the plant more effectively. It was first discovered in the Netherlands in 2005, before spreading rapidly, causing €25–30 million of damage annually by 2010. Three cases appeared in Scotland in 2009 and one in 2010. Host and symptoms The host for ''Dickeya solani'' is the potato plant (''Solanum tuberosum''). ''Dickeya'' spp. can be the causal agents of soft rots and black leg. The symptoms that this bacteria causes can at times not be easily distinguished from the symptoms caused by ''Pectobacterium'' spp, since both pathogens induce a rotting of the plant tissue and black leg symptoms on the host. Black leg symptoms consist of wet, black rot on the stem that spread up from the original seed tuber. Symptoms of a ''Dickeya ...

Dickeya Dadantii
''Dickeya dadantii'' is a gram-negative bacillus that belongs to the family Pectobacteriaceae. It was formerly known as ''Erwinia chrysanthemi'' but was reassigned as ''Dickeya dadantii'' in 2005. Members of this family are facultative anaerobes, able to ferment sugars to lactic acid, have nitrate reductase, but lack oxidases. Even though many clinical pathogens are part of the order Enterobacterales, most members of this family are plant pathogens. ''D. dadantii'' is a motile, nonsporing, straight rod-shaped cell with rounded ends. Cells range in size from 0.8 to 3.2 μm by 0.5 to 0.8 μm and are surrounded by numerous flagella (peritrichous). In the natural plant environment, ''D. dadantii'' causes plant maladies such as necrosis, blight and “soft rot,” which is a progressive tissue maceration. ''D. dadantii'' contains many pectinases that are able to macerate and break down the plant cell wall material. This exposed part of the plant releases nutrients that can facilitat ...

LPSN
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P. H. A. Sneath, 2003. A short hist .... The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Phytopathogen
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 populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
