The role of reduced and oxidized glutathione in plant development was investigated using wild carrot suspension cultures. Concentrations of GSH are lower in developing than in proliferating carrot cultures. Addition of 0.3 mM-buthionine sulfoximine (a glutathione synthesis inhibitor) to developing cultures decreased the cellular GSH levels and enhanced somatic embryogenesis while addition of 0....

We have initiated immunological and drug-binding studies on the tubulins from different higher plant species. Antibodies were raised against electrophoretically separated rose (Rosa sp.) tubulin alpha- and beta-subunits and characterized by immunoblot autoradiographic assays. Each IgG preparation bound to its antigen and cross-reacted differentially with the respective tubulin subunits from an ...

The causal fungus of pear scab, Venturia nashicola, grows slowly and rarely produces conidia on artificial media in the laboratory, but it produced conidia on the Cheongah medium containing Cheongah powder. V. nashicola grew too slow to produce conidia until 15 days after cultivation but produced conidia with 4 × 104 conidia/plate 30 days after cultivation on the Cheongah medium containing 1% C...

Larval rearing of Bactrocera invadens Drew, Tsuruta & White (Diptera: Tephritidae) on artiÞcial diet is described. The adaptation process for this insect, when moved from whole mango, Mangifera indica L., fruit rearing to artiÞcial diet based on wheat bran, took between three and Þve generations to reach theplateauof quality control parameters observed for rearing the insect onwhole mango fruit...

The effects of various pulsed electric field (PEF) parameters on the extraction of polyacetylenes from carrot slices were investigated. Optimised conditions with regard to electric field strength (1-4 kV/cm), number of pulses (100-1500), pulse frequency (10-200 Hz) and pulse width (10-30 μs) were identified using response surface methodology (RSM) to maximise the extraction of falcarinol (FaOH)...

• Utilising agri-food wastes for biopolymer production has the added benefit of sustainable waste management. Feedstocks were assessed using a multi-criteria decision analysis method. Cereal straw high theoretical availability, but various competing uses. Underutilised and low-cost food processing (e.g., onion peels carrot tops) are promising feedstocks production. The use renewable resources i...

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent liver diseases associated with an altered lifestyle, besides genetic factors. The control and management of NAFLD mostly depend on lifestyle modifications, due to the lack of a specific therapeutic approach. In this context, we assessed the effect of carrot juice on the development of high fructose-induced hepatic steatosis....

The low content of iodine (I) and selenium (Se) forms available to plants in soil is one of the main causes of their insufficient transfer in the soil-plant-consumer system. Their deficiency occurs in food in the majority of human and farm animal populations around the world. Both elements are classified as beneficial elements. However, plant response to simultaneous fertilization with I and Se...

Antioxidant activities of ethanolic extracts of Ardisia japonica Blume., Ageartum conyzoides Linn., and Cocculus hirsutus Linn Diels. leaves was determined qualitatively and quantitatively in this research. 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical solution was used to investigate free radical scavenging activity of these leaves extracts. Ascorbic acid (Vitamin C) was used as the stand...
