"Pseudomonas oryzae" is a species of pseudomonad bacteria. [1]
Pseudomonas is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 validly described species. The 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.
Pseudomonas putida is a Gram-negative, rod-shaped, saprotrophic soil bacterium.
Aspergillus is a genus consisting of a few hundred mold species found in various climates worldwide.
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.
Magnaporthe grisea, also known as rice blast fungus, rice rotten neck, rice seedling blight, blast of rice, oval leaf spot of graminea, pitting disease, ryegrass blast, Johnson spot, neck blast, and Imochi (Japanese:稲熱) is a plant-pathogenic fungus and model organism that causes a serious disease affecting rice. It is now known that M. grisea consists of a cryptic species complex containing at least two biological species that have clear genetic differences and do not interbreed. Complex members isolated from Digitaria have been more narrowly defined as M. grisea. The remaining members of the complex isolated from rice and a variety of other hosts have been renamed Magnaporthe oryzae, within the same M. grisea complex. Confusion on which of these two names to use for the rice blast pathogen remains, as both are now used by different authors.
Aspergillus oryzae, also known as kōji mold, is a filamentous fungus used in East Asia to saccharify rice, sweet potato, and barley in the making of alcoholic beverages such as sake and shōchū, and also to ferment soybeans for making soy sauce and miso. However, in the production of fermented foods of soybeans such as soy sauce and miso, Aspergillus sojae is mainly used instead of A. oryzae. A. oryzae is also used for the production of rice vinegars. Barley kōji (麦麹) or rice kōji (米麹) are made by fermenting the grains with A. oryzae hyphae.
Pseudomonas aeruginosa is a common encapsulated, Gram-negative, strict aerobic, 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.
Piceid is a stilbenoid glucoside and is a major resveratrol derivative in grape juices. It can be found in the bark of Picea sitchensis. It can also be isolated from Reynoutria japonica, the Japanese knotweed.
Pseudomonas syringae is a rod-shaped, Gram-negative bacterium with polar flagella. As a plant pathogen, it can infect a wide range of species, and exists as over 50 different pathovars, all of which are available to researchers from international culture collections such as the NCPPB, ICMP, and others.
Pseudomonas coronafaciens is a Gram-negative bacterium that is pathogenic to several plant species. Following ribotypical analysis several pathovars of Pseudomonas syringae were incorporated into this species.
Nuclease S1 is an endonuclease enzyme that splits single-stranded DNA (ssDNA) and RNA into oligo- or mononucleotides. This enzyme catalyses the following chemical reaction
Cefsulodin is a third-generation cephalosporin antibiotic that is active against Pseudomonas aeruginosa and was discovered by Takeda Pharmaceutical Company in 1977.
The Pseudomonas exotoxin is an exotoxin produced by Pseudomonas aeruginosa. Vibrio cholerae produces a similar protein called the Cholix toxin.
In molecular biology, Xanthomonas sRNA are small RNAs which have been identified in various species of the bacterium Xanthomonas.
Orseolia oryzae, also called the Asian rice gall midge, is a species of small fly in the family Cecidomyiidae. It is a major insect pest of rice. The damage to the crop is done by the larvae which form galls commonly known as "silver shoots" or "onion shoots". The rice plant is stunted and the seed heads fail to develop.
Xanthomonas oryzae pv. oryzae is a bacterial pathovar which causes a serious blight of rice, other grasses and sedges.
Rhizopus oryzae is a filamentous heterothallic microfungus that occurs as a saprotroph in soil, dung, and rotting vegetation. This species is very similar to Rhizopus stolonifer, but it can be distinguished by its smaller sporangia and air-dispersed sporangiospores. It differs from R. oligosporus and R. microsporus by its larger columellae and sporangiospores. R. oryzae is used economically in the production of the enzymes, glucoamylase and lipase, in the synthesis of organic acids, and in various fermented foods. The many strains of R. oryzae produce a wide range of enzymes such as carbohydrate digesting enzymes and polymers along with a number of organic acids, ethanol and esters giving it useful properties within the food industries, bio-diesel production, and pharmaceutical industries. It is also an opportunistic pathogen of humans causing mucormycosis.
Xanthoferrin is an α-hydroxycarboxylate-type of siderophore produced by xanthomonads. Xanthomonas spp. secrete xanthoferrin to chelate iron under low-iron conditions. The xanthoferrin siderophore mediated iron uptake supports bacterial growth under iron-restricted environment.
Samuel S. Gnanamanickam is an Indian plant pathologist. He is known for his research on diversity of rice pathogens, molecular breeding of indica rices for disease resistance and for developing superior strains of beneficial strains of rhizosphere bacteria for biological control of rice diseases. He is a fellow of the National Academy of Agricultural Sciences and National Academy of Biological Sciences of India and was Chair of the biological control committee at the American Phytopathological Society. He was named by Marquis Who's Who as a noteworthy plant pathologist.
