Raphanus sativus L. var niger (black radish) is a plant of the cruciferous family with important ethnobotanical uses for the treatment of gallstones in Mexican traditional medicine. It has been established that the juice of black radish decreases cholesterol levels in plasma and dissolves gallstones in mice. Glucosinolates, the main secondary metabolites of black radish, can hydrolyze into its ...

Radish seeds (Raphanus sativus, Mino variety) were exposed to full-wave rectified sinusoidal magnetic fields (MF) of strengths 40 mT, 80 mT, and 110 mT for 2.5, 5, and 10 min each, and its effects have been investigated on germination, seedling growth, and yield. Seeds were sown following the MF treatment according to the protocol of the International Seed Testing Association (ISTA) under contr...

Ogura cytoplasmic male sterility (CMS) in radish (Raphanus sativus) is caused by an aberrant mitochondrial gene, Orf138, that prevents the production of functional pollen without affecting female fertility. Rfo, a nuclear gene that restores male fertility, alters the expression of Orf138 at the post-transcriptional level. The Ogura CMS/Rfo two-component system is a useful model for investigatin...

The knowledge of flavonoids involved in plant-plant interactions and their mechanisms of action are poor and, moreover, the structural characteristics required for these biological activities are scarcely known. The objective of this work was to study the possible in vitro phytotoxic effects of 27 flavonoids on the germination and early radical growth of Raphanus sativus L. and Lepidium sativum...

The chemical composition of the essential oil of the flowering aerial parts of Monarda didyma L. cultivated in central Italy was analyzed by Gas Chromatography/Mass Spectrometry (GC/MS). The major compounds of the oil were thymol (59.3%), p-cymene (10.3%), terpinolene (9.2%), δ-3-carene (4.4%), myrcene (3.7%), and camphene (3.4%). The essential oil was tested in vitro for its anti-germination a...

Young radish (Raphanus sativus L), a member of the mustard family (Cruciferae), is a common ingredient of Kimchi. Although few reports have described anaphylaxis to cruciferous vegetables, we report the case of anaphylaxis induced by contact with young radish. A 46-year-old female with a history of contact allergy to metal presented to our emergency room (ER) with dizziness, generalized eruptio...

Polar transport of kinetin-8-(14)C occurred in segments of petioles, hypocotyls, and roots of radish (Raphanus sativus L.). The polarity was basipetal in petioles and hypocotyls and acropetal in roots. In segments excised from seedlings with fully expanded cotyledons, indole-3-acetic acid was required for polarity to develop. In hypocotyl segments isolated at this stage, basipetal and acropetal...

Nurseries producing apple and rose rootstock plants, apple orchards as well as rose production often experience replanting problems after several cultivations at the same site when a chemical soil disinfectant is not applied. The etiology of apple and rose replanting problems is most likely caused by soil-borne pathogen complex, defined as "replant disease (RD)". Symptoms typical of RD are redu...

The aqueous extract from Carya cathayensis Sarg. exocarp was centrifuged, filtered, and separated into 11 elution fractions by X-5 macroporous resin chromatography. A phenolic compound, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from the fractions with the strongest phytotoxicity by bioassy-guided fractionation, and investigated for phytotoxicity on lettuce (Latuca sativa L.), radish (Rap...

Pulmonary fibrosis is a progressive disease of the lungs, which leads to death in human. It has been suggested that transforming growth factor beta 1 (TGF-β1) together with oxidative stress play a central role in the pathogenesis of the ailment. The objective of this study was to evaluate the possible curative effects of black radish, Raphanus sativus L. var niger (RSN) on bleomycine (BLM) -ind...
