Summary of "Allelopathy of yellow fieldcress (Rorippa sylvestris): Identification and characterization of phytotoxic constituents."

Both the neutral and acidic fractions of the acetone extract of yellow fieldcress (Kireha-inugarashi,Rorippa sylvestris Besser) inhibited lettuce seed germination. Salicylic,p-hydroxybenzoic, vanillic, and syringic acid were identified in the acidic fraction. In the neutral fraction, hirsutin (8-methylsulfinyloctyl isothiocyanate), 4-methoxyindole-3-acetonitrile, and pyrocatechol were identified. Bioassay using a root exudate recirculating system showedR. sylvestris during flowering inhibited the lettuce seedling growth. Hirsutin (13μg/plant/day) and pyrocatechol (9.3μg/plant/day) were the major compounds released into the rhizosphere. Several combinations of pyrocatechol,p-hydroxybenzoic acid, vanillic acid, and hirsutin reduced lettuce seedling growth. These compounds seemed to be allelochemicals.

Medical and Biotech [MESH] Definitions

A plant genus of the family TROPAEOLACEAE. The common nasturtium is a plant that grows 2.4-3.6 m (8-12 feet) tall and has funnel-shaped flowers that are commonly yellow-orange with red spots or stripes and have a long spur that contains sweet nectar. Some species in this genus are called watercress which is also a common name for RORIPPA and NASTURTIUM.

Vaccine used to prevent YELLOW FEVER. It consists of a live attenuated 17D strain of the YELLOW FEVER VIRUS.

A rare condition characterized by the presence of yellow nails, LYMPHEDEMA, and/or PLEURAL EFFUSION with respiratory tract involvement. Abnormal lymphatic network may play a role in its etiology. Occasionally inherited, yellow nail syndrome mostly is sporadic without apparent family history.

A plant family of the order Capparales, subclass Dilleniidae, class Magnoliopsida. They are mostly herbaceous plants with peppery-flavored leaves, due to gluconapin (GLUCOSINOLATES) and its hydrolysis product butenylisotrhiocyanate. The family includes many plants of economic importance that have been extensively altered and domesticated by humans. Flowers have 4 petals. Podlike fruits contain a number of seeds. Cress is a general term used for many in the Brassicacea family. Rockcress is usually ARABIS; Bittercress is usually CARDAMINE; Yellowcress is usually RORIPPA; Pennycress is usually THLASPI; Watercress refers to NASTURTIUM; or RORIPPA or TROPAEOLUM; Gardencress refers to LEPIDIUM; Indiancress refers to TROPAEOLUM.

A mitosporic Loculoascomycetes fungal genus including several plant pathogens and at least one species which produces a highly phytotoxic antibiotic. Its teleomorph is Lewia.
