Hydrogenophaga pseudoflava is a bacterium from the Comamonadaceae family. [4]
Hemichordata is a phylum which consists of triploblastic, eucoelomate, and bilaterally symmetrical marine deuterostome animals, generally considered the sister group of the echinoderms. They appear in the Lower or Middle Cambrian and include two main classes: Enteropneusta, and Pterobranchia. A third class, Planctosphaeroidea, is known only from the larva of a single species, Planctosphaera pelagica. The class Graptolithina, formerly considered extinct, is now placed within the pterobranchs, represented by a single living genus Rhabdopleura.
Pseudomonas is a genus of Gram-negative bacteria belonging to the family Pseudomonadaceae in the class Gammaproteobacteria. The 348 members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture in vitro and availability of an increasing number of Pseudomonas strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include P. aeruginosa in its role as an opportunistic human pathogen, the plant pathogen P. syringae, the soil bacterium P. putida, and the plant growth-promoting P. fluorescens, P. lini, P. migulae, and P. graminis.
Pseudomonas fluorescens is a common Gram-negative, rod-shaped bacterium. It belongs to the Pseudomonas genus; 16S rRNA analysis as well as phylogenomic analysis has placed P. fluorescens in the P. fluorescens group within the genus, to which it lends its name.
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 animal damage can also cause stress to the plant resulting in cankers. Other causes of cankers is pruning when the bark is wet or using un-sterilized tools.
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. Another distantly related family of flies, Tephritidae, are true fruit flies because they are frugivorous, and include apple maggot flies and many pests. The best known species of the Drosophilidae is Drosophila melanogaster, within the genus Drosophila, also called the "fruit fly." Drosophila melanogaster is used extensively for studies concerning genetics, development, physiology, ecology and behaviour. Many fundamental biological mechanisms were discovered first in D. melanogaster. The fruit fly is mostly composed of post-mitotic cells, has a very short lifespan, and shows gradual aging. As in other species, temperature influences the life history of the animal. Several genes have been identified that can be manipulated to extend the lifespan of these insects. Additionally, Drosophila subobscura, also within the genus Drosophila, has been reputed as a model organism for evolutionary-biological studies, along with D. sechellia for the evolution of host specialization on the toxic noni fruit and Scaptomyza flava for the evolution of herbivory and specialist on toxic mustard leaves.
Cystovirus is a genus of double-stranded RNA viruses which infects bacteria. It is the only genus in the family Cystoviridae. The name of the group cysto derives from Greek kystis which means bladder or sack. There are seven species in this genus.
Aesculus flava, also known commonly as the common buckeye, the sweet buckeye, and the yellow buckeye, is a species of deciduous tree in the subfamily Hippocastanoideae of the family Sapindaceae. The species is native to the Ohio Valley and Appalachian Mountains of the Eastern United States. It grows in mesophytic forest or floodplains, generally in acid to circumneutral soil, reaching a height of 20m to 48m.
Pseudomonas aeruginosa is a common encapsulated, Gram-negative, aerobic–facultatively anaerobic, rod-shaped bacterium that can cause disease in plants and animals, including humans. A species of considerable medical importance, P. aeruginosa is a multidrug resistant pathogen recognized for its ubiquity, its intrinsically advanced antibiotic resistance mechanisms, and its association with serious illnesses – hospital-acquired infections such as ventilator-associated pneumonia and various sepsis syndromes. P. aeruginosa is able to selectively inhibit various antibiotics from penetrating its outer membrane - and has high resistance to several antibiotics. According to the World Health Organization P. aeruginosa poses one of the greatest threats to humans in terms of antibiotic resistance.
Hydrogenophaga is a genus of comamonad bacteria, several of which were formerly classified in the genus Pseudomonas.
In enzymology, a carbon-monoxide dehydrogenase (cytochrome b-561) (EC 1.2.2.4) is an enzyme that catalyzes the chemical reaction
Curvibacter gracilis is a Gram-negative bacterium from the genus Curvibacter and family Comamonadaceae, which was isolated from well water.
Hydrogenophaga atypica is a Gram-negative, oxidase-positive, rod-shaped, motile bacterium from the Comamonadaceae family, which was isolated from wastewater from an activated sludge. The colonies of H. atypica are pale yellow.
Hydrogenophaga bisanensis is a Gram-negative, non-spore-forming, rod-shaped bacterium from the Comamonadaceae family, which was isolated from wastewater from a textile dye works in Korea. Colonies of H. bisanensis are moderate yellow in color.
Hydrogenophaga caeni is a Gram-negative, anaerobic, catalase- and oxidase-positive, motile bacterium from the Comamonadaceae family, with a single polar flagellum, which was isolated from an activated sludge. Colonies of H. caeni are white colored.
Hydrogenophaga defluvii is a Gram-negative, oxidase-positive, rod-shaped, motile bacterium from the Comamonadaceae family, which was isolated from wastewater. Colonies of H. defluvii are pale yellow in color.
Hydrogenophaga palleronii is a bacterium from the Comamonadaceae family, which has the ability to degrade 4-aminobenzenesulfonate.
Hydrogenophaga taeniospiralis is a catalase-negative bacterium from the Comamonadaceae family.
Harperocallis is a genus of flowering plants in the family Tofieldiaceae, native to Florida and northwestern South America. It was originally described as a monotypic genus, based on the Floridian H. flava, in 1968, but was expanded in 2013 to include ten South American species formerly placed in Isidrogalvia.
Xenophilus azovorans is a bacterium from the genus Xenophilus which has been isolated from soil in Switzerland.
Scaptomyza flava is an herbivorous leaf mining fly species in the family Drosophilidae. In Latin, flava means golden or yellow. The fly is amber to dark brown in color and approximately 2.5 mm in length. In Europe and New Zealand the larvae are pests of plants in the order Brassicales, including arugula, brassicas, broccoli, Brussels sprouts, bok choy, cabbage, canola, cauliflower, horseradish, kale, kohlrabi, napa cabbage, nasturtium, radish, rapini, rutabaga, turnip, wasabi and watercress. In New Zealand, its range has expanded to include host species that are intercropped with salad brassicas, including gypsophila, otherwise known as baby's breath, which is in the pink family (Caryophyllaceae) and the pea in the Fabaceae. More typically, S. flava is oligophagous within the Brassicales. Scaptomyza are unusual within the Drospophilidae because the group includes species that are truly herbivorous. Other herbivorous drosophilids include D. suzukii, which attacks fruit very early during ripening and species within the genus Lordiphosa, from Africa and Asia, which also include leaf miners. Most drosophilids feed on microbes associated with decaying vegetation and sap fluxes.
