Keywords: Nutrients localization, Triticum biofortification, X-ray microanalysis Certified seeds of Triticum aestivum L. cv Nabão (0Ts) were grown in walk-in growth chamber (EHHF10000, Aralab, Portugal), under environmental controlled conditions (80% RH; 24/20C day/night temperatures; PPFD of ca 700 µmol m -2 s -1 , 12 h photoperiod), in pots irrigated with a standard solution (1Ts), during 1 month following germination. Thereafter, until the physiological maturity, half of the pots kept the same irrigation solution (1Ts), while the other half was submitted to a five fold concentration of all the nutrients (1T5s). The seeds 1T5s were sown and grown again using the initial standard nutrient solution (now called 2Ts) and solutions containing 5, 7, 10 and 13 times the concentration of all the nutrients (2T5s, 2T7s, 2T10s and 2T13s, respectively). In the seeds of 1Ts, 1T5s, 2Ts, 2T5s, 2T7s, 2T10s and 2T13s, Zn concentration increased about 7.18, 6.10, 9.92, 8.87, 4.73, 9.00 and 9.23 fold, whereas Fe augmented 1.01, 1.35, 3.91, 4.95, 5.10, 8.98 and 11.06 times, respectively, compared with the 0Ts Zn and Fe levels. The pattern of nutrient accumulation, as seen by SEM, coupled with X-ray microanalysis, throughout a line scan on transversal sections of the grains, revealed a non-homogeneous distribution of the nutrients, despite the distribution of the mean values shown were: Cu 0Ts
TRACE ELEMENTS, GLUTATHIONE AND DIABETES – HOW IMPROVED PLANTS COULD IMPROVE HEALTH. RESULTS OF A LITERATURE SURVEY Peter Schröder Helmholtz Zentrum Muenchen, Research Unit Microbe Plant Interactions, Nehuerberg. Diabetes mellitus is a major endocrine disorder responsible for poor metabolic control and increased risk of cardiovascular disease, renal failure, blindness or diabetic cataract, and other symptoms including atherosclerosis and AGE (advanced glycation end) products. Antioxidants play an important role to protect against damage by reactive oxygen species and their role in diabetes has been evaluated. Many plant extracts and products have been shown to possess significant antioxidant activity and are used for dietary purposes. But uptake of trace elements seems to be of equal importance. For example, patients with diabetes have significantly lower levels of zinc in their blood compared to the control subjects. On the other hand, chromium is a trace mineral that improves the action of the hormone insulin and is directly implicated in the metabolism of carbohydrates, protein and fats. Magnesium sems to play a role as a second messenger for insulin action, whereas insulin itself has been identified to be a regulatory factor of intracellular magnesium accumulation. A lack of magnesium has been linked to insulin resistance, glucose intolerance and diabetes complications. Vanadium or its derivatives mimic the metabolic actions of insulin. In rodents, vanadate also sensitizes peripheral tissues to insulin. Hence it may improve blood sugar control in diabetes. Only few studies have examined whether selenium status influences risk for diabetes, but the available results are conflicting. There is also in vitro and clinical evidence that an abnormal glutathione status in diabetes patients might be involved in β-cell dysfunction and in the pathogenesis of long-term complications. Therefore some interest has developed in a possible modification of the glutathione status during the therapy of diabetes. Overall, information is urgently needed on the interactions of antioxidants and trace elements on diabetes, and on a possible role of fortified food ingredients in a healthy diet.
