Tomato (Lycopersicon esculentum Mill.) plants, which normally do not accumulate glycinebetaine (GB), are susceptible to chilling stress. Exposure to temperatures below 10 degrees C causes various injuries and greatly decreases fruit set in most cultivars. We have transformed tomato (cv. Moneymaker) with a chloroplast-targeted codA gene of Arthrobacter globiformis, which encodes choline oxidase ...

This study was undertaken to compare the levels of ascorbic acid, vitamin C, flavonoids, nitrate, and oxalate in 27 spinach varieties grown in certified organic and conventional cropping systems. Liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-(ESI)MS/MS) of methanolic extracts of spinach demonstrated 17 flavonoids, including glucuronides and acylated di- and triglyco...

To improve the efficiency of nitrogen (N) fertilization, it is necessary to perform rapid direct measurements in field rather than time-consuming laboratory-based chemical analysis. Herein, crop and soil data from early stages cabbage growth were acquired through two fall cultivations. Chlorophyll meter value, height, projected leaf area evaluated as indicators. A positive correlation was obser...

We report the development of a sensitive, and specific, competitive, antigen-capture enzyme-linked immunosorbent assay for the measurement of channel catfish (Ictalurus punctatus) growth hormone (cfGH). The detection limit of the assay (90% binding) was 2.0ng/ml and the ED(50) value (standard curve range 150-0.59 ng/ml) was 67.3 ng/ml. Recovery of cfGH-spiked plasma samples was determined to be...

Patients suffering from Refsum's disease show mutations in the enzyme necessary for the degradation of phytanic acid. Accumulation of this tetramethyl-branched fatty acid in inner organs leads to severe neurological and cardiac dysfunctions which can even result in death. Thus, patients with Refsum's disease have to follow a specific diet resigning foods with high levels of phytanic acid and tr...

Crude extract of Myrica esculenta fruits, a wild edible species of Indian Himalayan Region, was evaluated for phenolic compounds and antioxidant properties. Results revealed significant variation in total phenolic and flavonoid contents across populations. Among populations, total phenolic content varied between 1.78 and 2.51 mg gallic acid equivalent/g fresh weight (fw) of fruits and total fla...

BACKGROUND Organic agriculture involve plants which are cultivated without using synthetic pesticides, herbicides or fertilizers and promotes biodiversity, biological cycles and improve the product quality. The carotenoids, total polyphenols and the antioxidant activity from skins of some wine and table grapes cultivated in organic and conventional agriculture were studied. RESULTS The main c...

The relationship between the mRNA level and the corresponding protein level of the cry1Ab/c gene is not well characterized in transgenic rice (Bt-ShanYou63). In this study, we compared cry1Ab/c mRNA and its protein expression in leaves at different growth stages in Bt-ShanYou63 rice. The results demonstrated that both cry1Ab/c mRNA and its protein levels changed at all of the growth stages. The...

Drought and salt are major abiotic stresses that adversely affect crop productivity. Thus, identification of factors that confer resistance to these stresses would pave way to increasing agricultural productivity. When grown on soil in green house longer than 5 weeks, transgenic Arabidopsis plants that overexpress an ATP-binding cassette (ABC) transporter, AtABCG36/AtPDR8, produced higher shoot...

Volatile compounds, physicochemical and sensory attributes of four sweet cherry cultivars (Canada giant, Ferrovia, Lapins and Skeena) grown in Northern Greece were determined. Eighteen volatile compounds were identified and semi-quantified in cherries using solid phase micro extraction in combination with gas chromatography/mass spectrometry (SPME-GC/MS). Carbonyl compounds were the most abunda...
