Electrical impedance spectra (100 Hz-800 kHz) were measured in leaves of Peperomia obtusifolia L. (a succulent) and Brassica oleracea L. (cabbage). By measuring impedances at three or more inter-electrode distances in a single leaf, electrode impedance and specific tissue impedance were separated. Analysis of impedance data from B. oleracea leaves in relation to an equivalent circuit model show...

Juvenile hormone (JH) biosynthesis and the effects of synthetic Manduca sexta allatostatin (Mas-AS) and M. sexta allatotropin (Mas-AT) were investigated in isolated corpora allata (CA) of Vth stadium larvae of the tomato moth, Lacanobia oleracea. Reversed-phase high-performance liquid chromatography (RP-HPLC) of JH extracted from CA shows that larvae produce predominantly JH II and its correspo...

Brassica oleracea vegetables, such as broccoli (B. oleracea L. var. italica) and cauliflower (B. oleracea L. var. botrytis), are known to contain bioactive compounds associated with health, including three classes of photosynthetic lipid-soluble compounds: carotenoids, chlorophylls, and tocopherols. Carotenoids and chlorophylls are photosynthetic pigments. Tocopherols have vitamin E activity. D...

Objective(s) Portulaca oleracea L. is a herbaceous weed from portulacaceae family. It can be found in many parts of the world. Modern pharmacological studies have demonstrated that P. oleracea have antioxidant effects. The protective effect of aqueous and ethanolic extract of P. oleracea against cisplatin-induced renal toxicity was studied in rats. Materials and Methods Single intraperitonea...

The evolution of plant morphologies during domestication events provides clues to the origin of crop species and the evolutionary genetics of structural diversification. The CAULIFLOWER gene, a floral regulatory locus, has been implicated in the cauliflower phenotype in both Arabidopsis thaliana and Brassica oleracea. Molecular population genetic analysis indicates that alleles carrying a nonse...

The number of cases obesity and type 2 diabetes mellitus (T2DM) is part the metabolic syndrome case. Purslane (Portulaca oleracea L.) a plant that has been clinically tested potential to prevent treat as well pathogenic pathophysiological activities cause disease. aim this study discuss conclude information regarding activity use purslane (P. oleracea) an antimetabolic. This review article base...

A water-soluble chlorophyll protein (WSCP) in cauliflower (Brassica oleracea L.) was purified and its N-terminal sequence was determined. Forty-six of 48 residues of the sequence completely matched those of the drought-induced 22-kD protein (BnD22) in rapeseed (Brassica napus L.). All 40 sequenced residues of WSCP from rapeseed were perfectly matched to those of BnD22. Thus, WSCP may be identic...
