(American Heritage Dictionary, 2d ed)Agrochemicals: Chemicals used in agriculture. These include pesticides, fumigants, fertilizers, plant hormones, steroids, antibiotics, mycotoxins, etc.Denaturing Gradient Gel Electrophoresis: Electrophoresis in which various denaturant gradients are used to induce nucleic acids to melt at various stages resulting in separation of molecules based on small sequence differences including SNPs. The denaturants used include heat, formamide, and urea.Pseudomonas: A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.Pseudomonas aeruginosa: A species of gram-negative, aerobic, rod-shaped bacteria commonly isolated from clinical specimens (wound, burn, and urinary tract infections). It is also found widely distributed in soil and water. P. aeruginosa is a major agent of nosocomial infection.Soil: The unconsolidated mineral or organic matter on the surface of the earth that serves as a natural medium for the growth of land plants.Antifungal Agents: Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.Databases, Chemical: Databases devoted to knowledge about specific chemicals.Agar: A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.Bacillus subtilis: A species of gram-positive bacteria that is a common soil and water saprophyte.Bacillus cereus: A species of rod-shaped bacteria that is a common soil saprophyte. Its spores are widespread and multiplication has been observed chiefly in foods. Contamination may lead to food poisoning.p-Fluorophenylalanine: 3-(p-Fluorophenyl)-alanine.Hemorrhagic Fever, American: Diseases caused by American hemorrhagic fever viruses (ARENAVIRUSES, NEW WORLD).Xylariales: An order of ascomycetous FUNGI which includes many economically important plant parasites as well as saprophytes.Ananas: A plant genus of the family BROMELIACEAE known for the edible fruit that is the source of BROMELAINS.Persea: A plant genus in the LAURACEAE family. The tree, Persea americana Mill., is known for the Avocado fruit, the food of commerce.Phytophthora: A genus of destructive parasitic OOMYCETES in the family Peronosporaceae, order Peronosporales, affecting numerous fruit, vegetable, and other crops. Differentiation of zoospores usually takes place in the sporangium and no vesicle is formed. It was previously considered a fungus.Plant Roots: The usually underground portions of a plant that serve as support, store food, and through which water and mineral nutrients enter the plant. (From American Heritage Dictionary, 1982; Concise Dictionary of Biology, 1990)Cinnamomum aromaticum: A plant species of the genus CINNAMOMUM that contains CINNAMATES and has been used in traditional Chinese medicine (DRUGS, CHINESE HERBAL).Oryza sativa: Annual cereal grass of the family POACEAE and its edible starchy grain, rice, which is the staple food of roughly one-half of the world's population.Aspergillus oryzae: An imperfect fungus present on most agricultural seeds and often responsible for the spoilage of seeds in bulk storage.

Lippsidoquinone; TRITERPENES; SESQUITERPENES; and THYMOL have been found in this genus. Plant extracts have cytotoxic activity. It is sometimes called Mexican oregano but that confuses it with real oregano (ORIGANUM).Apium graveolens: A plant species of the family APIACEAE.
