Raphanus sativus L. belongs to family Brassicaceae and is more commonly known as Radish. Radish has long been grown as a food crop and are of high medicinal value. R. sativus seeds and leaves contain ‘raphanin’ which has been found to possess antibacterial and antifungal potential. In the present study, R. sativus root juice was evaluated for its antimicrobial potential against five bacterial s...

Wild radish is an annual plant that exhibits broad spectrum induced resistance to herbivores. In two experiments, we placed potted plants [control, manually clipped, and damaged byPieris rapae(L.) larvae] in theÞeld andassayed forovipositionbyP. rapae(a specialist herbivore), damage by ßea beetles (a specialist herbivore), and damage by rabbits (a generalist herbivore). Induced responses attrac...

Nutrient recycling in a space-based Bioregenerative Life Support System (BLSS) will require an understanding of nutrient dosage effects on crop production, plant tissue partitioning, and geochemical fates within crop systems. Sodium (Na+), fluoride (F−), and iodide (I−) are found in human waste streams. These elements were examined using crops in hydroponic systems. Lettuce, radish, spinach, an...

The behavior of Heterorhabditis zealandica Poinar strain T327 was investigated in the presence of the cabbage maggot, Delia radicum L., and plants that are susceptible to D. radicum infestation. Newly formed puparia and freeze-killed third instar larvae were attractive to infective nematodes. Newly harvested infective nematodes did not respond to the puparia, whereas 1-month-old and 2-month-old...

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...

Objective: Very recent studies have reported positive effects of dietary nitrate on the oxygen consumption during exercise. This research aimed to study the effect of moderate dose of high-nitrate vegetables, watercress (Nasturtium officinale) and red radish (Raphanus sativus) compared with a control group on the incremental treadmill exercise test following a standard Bruce protocol controlled...

The evolutionary mechanisms underlying the maintenance of invariant traits are poorly understood, partly because the lack of variance makes these mechanisms difficult to study. Although the number of cotyledons that plant species produce is highly canalized, populations of plants frequently contain individuals with abnormal cotyledon numbers. In a garden study with 1857 wild radish plants from ...

Crop-wild hybridization may produce offspring with lower fitness than their wild parents due to deleterious crop traits and outbreeding depression. Over time, however, selection for improved fitness could lead to greater invasiveness of hybrid taxa. To examine evolutionary change in crop-wild hybrids, we established four wild (Raphanus raphanistrum) and four hybrid radish populations (R. raphan...

Materials Thrombin (bovine plasma, 1880 NIH units/mg protein) was purchased from Sigma (St. Louis, MO, U.S.A.). Simvastatin, fluvastatin and pravastatin were supplied by Merck & Co. (Rahway, N.J., U.S.A.), Novartis Pharma Inc. (Tokyo, Japan) and Sankyo Co. (Tokyo, Japan), respectively. TFLLR-NH2 (PAR1-activating peptide) and GYPGKFNH2 (PAR4-activating peptide) were purchased from Bachem (Bubend...
