As a candidate for bioherbicide, 4,8-dihydroxy-1-tetralone (4,8-DHT) was isolated from Caryospora callicarpa epicarp and its two enantiomers, S-(+)-isosclerone and R-(-)-regiolone, were separated by chiral high-performance liquid chromatography (HPLC) on a Chiralcel OD column with chiral stationary phase (CSP)-coated cellulose-tris(3,5-dimethylphenylcarbamate). Then, the phytotoxicity of 4,8-DH...

Trace elements play a significant role in biological processes. The aim of this study was to evaluate the trace elements of interest in kidney disease in commonly consumed greenhouse vegetables in Isfahan, Iran. Six kinds of greenhouse vegetables namely; Raphanus sativus (Radish), Cucumis sativus (Cucamber), Solanum lycopersicum (Tomato), green Capsicum annuum (Green bell pepper), yellow Capsic...

Foliar chemicals are variable within a plant and this may affect herbivore feeding preference. This study was carried out to quantify concentrations of primary (nitrogen, water, and total nonstructural carbohydrates) and secondary substances (sinigrin) in young and old leaves of Raphanus sativus L. and to evaluate performance and survival of a generalist herbivore Spodoptera litura F. feeding o...

El Rábano (Rhapanus sativus) es una hortaliza que se cultiva a nivel mundial por lo que, muchos productores utilizan químicos para tener mayor producción, alternativa evitar el uso de en cultivo rábano abonos verdes base algas sus ventajas nutricionales pueden aportar la agricultura. objetivo este trabajo fue evaluar comportamiento agronómico y productivo del “Raphanus sativus” bajo efecto biof...

The protective effects of an extract of young radish (Raphanus sativus L) cultivated with sulfur (sulfur-radish extract) and of sulforaphane, an isothiocyanate, on carbon tetrachloride (CCl(4))-induced liver injury were observed in mice. CCl(4) produced a marked increase in the serum level of alanine aminotransferase (ALT), primed lipid peroxidation, and resulted in intense necrosis due to oxid...

We developed a method for expression in Arabidopsis of a transgene encoding a cleavable chimeric polyprotein. The polyprotein precursor consists of a leader peptide and two different antimicrobial proteins (AMPs), DmAMP1 originating from Dahlia merckii seeds and RsAFP2 originating from Raphanus sativus seeds, which are linked by an intervening sequence ("linker peptide") originating from a natu...

In seedlings of Raphanus sativus (radish) and Sinapis alba (mustard), irradiation for 6 hours with far red light significantly increases the extractable activity of phenylalanine ammonia-lyase by the end of the light period. A schedule of 10 minutes red light-110 minutes darkness-10 minutes red-110 minutes darkness-10 minutes red-110 minutes darkness has no effect as compared to dark controls. ...

Monomeric cytochrome f from Japanese radish (Raphanus sativus L. var acanthiformis Makino) leaves was isolated in a homogeneous state with an A420.5/A277 of 7.6. Radish cytochrome f is a single polypeptide chain with a molecular weight of about 33,000. The midpoint potential is 350 mV. The amino acid analysis indicates the existence of 3 residues of half-cystine. Radish cytochrome f contains on...

The chemical composition of the essential oils of Salvia africana L., Salvia elegans Vahl, Salvia greggii A. Gray, Salvia mellifera Green and Salvia munzii Epling, cultivated in Eboli (Salerno, Southern Italy), was studied by means of GC and GC-MS analyses. In all, 88 compounds were identified, 54 for S. africana, accounting for 95.4% of the total oil, 55 for S. elegans (92.9%), 50 for S. gregg...

The present study was conducted to assess the physiological and biochemical responses of winter vegetable radish (Raphanus sativus L.) to salinity stress. Salt stress markedly reduced biomass production of both radish varieties. Shoot fresh and dry weights were significantly reduced under salt stress, higher reduction was found at 120 mM NaCl as compared. Salt stress significantly reduced chlor...
