This study was undertaken to estimate the contribution of meat and meat products consumption to the daily intakes of trace elements (Fe, Zn, Cu, Se), heme iron, and selected B vitamins (thiamine, riboflavin, niacin) in Italy. Meat and meat products were selected on the basis of their consumption frequency reported by the most recent nationwide dietary individual survey carried out in Italy (INN-CA study). The daily intakes of total iron and heme iron were 1.65 and 1.13 mg/person/day. Zinc intake was 3.65 mg/person/day. Beef made the main contribution to iron, heme iron, and zinc daily intakes. Copper daily intake was 107.3 mug/person/day, with meat products provided the highest contribution (40 mug/person/day). Daily intake of selenium (7.14 mug/person/day) was provided mainly by poultry consumption. Thiamine intake was 228 mug/person/day, and meat products were the main source (110 mug/person/day). Riboflavin intake was 136 mug/person/day, with both beef and meat products as the main contributors (40 mug/person/day). Niacin intake was 7.53 mg/person/day, and poultry was the main source (2.28 mg/person/day). Meat and meat products were a valuable source of micronutrients, supplying 47, 48, and 24% of zinc, niacin, and thiamin daily requirements, respectively, and over 10% of iron, copper, selenium, and riboflavin daily average requirement values of the italian RDAs calculated for the population involved in the survey (INN-CA study).

The amounts of Fe, and Zn were measured in maize seedlings infected by smut gall tumour (Ustilago maydis Dc. Cda.) and in healthy seedlings five days after infection. The amount of elements was also measured under different stress intensities. Due to the infection, as a biotic stress, the amount and distribution of examined elements have been changed. On the bases of the differences in the Fe distribution between the symptoms less and tumorial leaf parts, we have come to the conclusion that the infection also effects the mobilisation of Fe and Zn inside the plants. The Fe uptake was much higher in the infected plants and the tumour development also had an effect on the uptake and distribution of the examined elements. The experiments of infecting maize seedlings by monosporidial strain of crown gall tumour showed no tumour development. We found that the monosporidial strain also acts as a biotic stress and has an effect of iron and zinc distribution. We observed a slight difference in the iron and zinc contents in the roots of corn seedlings infected by different monosporidial sporidium concentrations, while the iron and zinc contents in the shoots were increased by the intensity of the infection. The roots do not form tumours. There is no difference between the roots of the infected and healthy corn seedlings. Since the Fe and Zn contents of the shoots of infected plants depend on the intensity of the infection, we have come to the conclusion that there must exist a „special” communication system regulating the transportation of the examined elements.In the experiments with infected maize seedlings, it became necessary to get the iron chlorosis before the disease reaches the lethal phase. Although most of the iron reserves are located in the embryo, to accelerate the chlorosis, the endosperm was removed, and it was observed, that the iron chlorosis appears later in maize seedlings when the endosperm is removed. The relative chlorophyll content of the first and second leaves was measured in iron efficient and iron deficient maize seedlings at different times.The higher IAA content of tumorial plant tissues is already known. The treatment with IAA decreases the iron concentration in the shoots and in the roots of +Fe precultured plants and increases at -Fe precultured ones. The TIBA retards the shoot-to-root transport of IAA. When the seedlings were treated simultaneously with IAA and TIBA, higher iron concentrations were observed in the shoots and in the roots of corn seedlings.We found extremely high iron concentrations in the roots of infected seedlings and, in line with this, serious damage to the roots was observed that this can be caused by the high iron content generated free radicals. The results demonstrate that IAA has a role in the shoot to root communication.

Foxtail millet (Setaria italica L.) is nutri-cereal crop having it is rich in β-carotene, vitamin B-complex and micronutrients like minerals. In the present research, we have studied biochemical properties and molecular profiling to identify the core set of foxtail millet (Setaria italic L.) accessions for high Iron (Fe) and Zinc (Zn) content. Total seventy-nine accessions and selected mutants variety PS4 of foxtail millet were used. The biochemical investigation revealed that accessions M2-106, IC120407, M3-61/HB-13, and IC120255 consist of high iron and zinc content. The genetic variability among the genotypes was revealed by 28 Promoter Anchored Amplified Polymorphic (PAAP-RAPD) primers of which OPE9+GC1, OPE9+CA1, UBC001+CA1, UBC001+TA1, UBC693+G1 showed 100% polymorphism, whereas UBC693+GC1 and OPE7+G1 showed 88% and 80% polymorphism, respectively, with an average of 45.95 % polymorphism. Total alleles per locus were 3.31, whereas, the average number of monomorphic and polymorphic alleles were 1.72 and 1.56, respectively. The extent of polymorphic information content (PIC) of PAAP-RAPD loci ranged from 0.5 to 0.87 with an average value of 0.41. For PAAP-RAPD, the maximum PIC value was observed in marker UBC693+GC1 (0.87 %) and the minimum were OPE5+CA1 and OPE9+CA1 (0.5 %). Molecular characterizations result showing highest similarity (0.932) between accessions Shrilakshmi and Prasad, whereas, the lowest similarity coefficient was observed between IC120255 and M3-75/AM-1 (0.697) with PS4.UPGMA dendrogram grouped the foxtail millet accessions in five clusters which marked high diversity in M3-61/HB-13 and M3-75/AM-1. It implies that PAAP-RAPD markers are significantly screened in the foxtail millet accessions and have enumerated high genetic diversity.
