Blackleg (potatoes)
Blackleg is a plant disease of potato caused by pectolytic bacteria that can result in stunting, wilting, chlorosis of leaves, necrosis of several tissues, a decline in crop yield, yield, and at times the death of the potato plant. The term "blackleg" originates from the typical blackening and decay of the lower plant stem, stem portion, or "leg", of the plant.De Boer S. H. 2004"Blackleg of potato" The Plant Health Instructor. DOI:10.1094/PHI-I-2004-0712-01 Blackleg in potatoes is most commonly caused by ''Pectobacterium atrosepticum'' (older synonym: ''Erwinia carotovora subsp. astroseptica''), a gram-negative, nonsporulating, facultative anaerobe that is also associated with soft rot of potatoes. While other bacterial species such as ''Pectobacterium carotovorum'' and ''Dickeya dadantii'' can exhibit symptoms similar to blackleg of potato, these pathogens exhibit broader host ranges, are present in different climates, and typically are more associated with soft rot diseases.Ali ...

Pectobacteriaceae
The ''Pectobacteriaceae'' are a family (biology), family of Gram-negative bacteria which largely consist of plant pathogens. This family is a member of the order Enterobacterales in the class Gammaproteobacteria of the phylum Pseudomonadota. The type species of this family is ''Pectobacterium''. The name ''Pectobacteriaceae'' is derived from the Latin term ''Pectobacterium'', referring the type genus of the family and the suffix "-aceae", an ending used to denote a family. Together, ''Pectobacteriaceae'' refers to a family whose nomenclatural type is the genus ''Pectobacterium''. Biochemical Characteristics and Molecular Signatures Source: Members of the family produce acid from N-acetylglucosamine and are negative for arginine dihydrolase, orthinine decarboxylase and lysine decarboxylase. These bacteria are catalase-positive, oxidase-negative, and do not produce hydrogen disulfide. Genomic analyses identified four conserved signature indels (CSIs) that are specific this fami ...

Bacterial Plant Pathogens And Diseases
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in mutualistic, commensal and pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
