Improving the concentration and bioavailability of zinc (Zn) in cereal grains is an important way to solve the problem of Zn deficiency in human body. The bioavailability of Zn is related to both its distribution and speciation in grains. In the current study, we examined the differences of Zn concentration, distribution, and speciation within grains among wheat cultivars with similar high grain yield but contrasting grain Zn concentration using synchrotron micro X-ray fluorescence (μ-XRF) and X-ray absorption near-edge structure (XANES). Results showed that compared to the low-Zn cultivar, the Zn concentration was 103, 50, 76, 33, and 64% higher in the crease region, aleurone layer, scutellum, embryonic axis, and endosperm of the high-Zn cultivar, respectively. Zinc mainly colocalized with phosphorus (P) in the aleurone layer and the scutellum, but less colocalization of Zn with P and a much lower concentration ratio of P/Zn were found in the high-Zn cultivar. Sulfur (S) is present in the form of scattered spots in the endosperm in accord with Zn, but the colocalization of Zn with S was predominant in the modified aleurone layer and the nucellar projection of the high-Zn cultivar. XANES results showed the lower proportion of Zn-phytate in the high-Zn cultivar. Findings indicated that it is possible to select the high-yield wheat cultivar with both high grain Zn concentration and high bioavailability, which provide a new perspective for genetic Zn biofortification.

“…The Mn content of cereals (wheat, oats, barley, and rye) is influenced by a number of factors, one of the most important being soil pH. According to the literature, a low soil pH means higher Mn uptake by crops, which in turn increases the Mn content of the grains [ 39 ]. The soil in our experiment is not acidic, but we measured 55.561–59.194 mg kg −1 Mn in oat grains, which is higher than reported by Bityutskii, (3.5–9.9 mg kg −1 ) [ 37 ].…”

In order to investigate the abiotic stress (drought) tolerance of oat (Avena sativa L.) with silicon and sulphur foliar fertilisation treatments, and monitor the effect of the treatments on the physiology, production, stress tolerance, plant, and grain quality of winter oat varieties, a field experiment was conducted in the growing season of 2020–2021. As a continuation of our article, published in another Special Issue of Plants, in this publication we evaluate the effect of silicon and sulphur treatments on the quality of winter oats. The whole grain sulphur content was significantly different between varieties. The foliar fertiliser treatments caused greater differences in both the carbon and nitrogen, and sulphur contents in the green plant samples, compared to the differences measured in the grain. Foliar treatments had a significant effect on the sulphur content of both plant samples and grains. Significant differences in the Al, Ba, Ca, Cu, Fe, K, Mn, Mo, Na, Ni, P, Pb, Sr, and Zn contents of oat grains were measured, both between treatments and between varieties. Winter oat varieties did not respond equally to the foliar fertiliser treatments in terms of either macronutrient or micronutrient content. When P, K, Ca, Mg, and S were summarised, the highest values were in the control plots. Significant differences in protein content were identified between winter oat varieties in response to the treatments, but the varieties did not respond in the same way to different foliar fertiliser treatments. Based on our results, we recommend the use of foliar fertilisation in oats in drought-prone areas.

“…While, Mn is the main element that is required in the control of the use of lipids and glucose and for activation of several enzymes (Li and Yang, 2018), increase of rate in the protein production, vitamin C and B; catalysis of hematopoiesis; adaptation of the endocrine; and increase in impervious function (Chen et al, 2018). Thus, in the human body, Mn deficiency reduces growth and productivity (Shi et al, 2020). Symptoms related to Mn deficiency involve deficiency of physical endurance, fatigue, reduced metabolism of cartilage and bone, the fingernails and hair slow growth, dermatitis, loss of weight, decreased fertility, improved inflammation, and allergic sensitivities (Ayodele and Bayero, 2010).…”

“…In Iran, 137 wheat cultivars grown in the calcareous soils with Fe deficiency had the grain concentration ranged between 21.1-96.6 mg kg -1 (Karami et al, 2009). Surveying in China performed by collecting 438 wheat grain samples from two regions that were categorized on soil pH (non-acid pH>7, and acid pH<7), showed that the average concentration of Mn was 43.7 mg kg -1 (ranging from 13.9 to 98.3 mg kg -1 ) (Shi et al, 2020). Average concentrations in (mg kg −1 ) of 13.0 for Mn and 66.7 for Fe in wheat grain reported by (Mohammed and Ahmad, 2014).…”

Manganese (Mn) and iron (Fe) are the two vital micronutrients for plants and moreover essential nutritional health components in humans. Iron deficiency is common in humans and causes many health issues. In this survey, wheat grains of two major wheat cultivars were analyzed for their Mn and Fe concentrations beside the natural gradient of micronutrient availability across Sulaymaniyah province, Iraqi Kurdistan. However only 20% and 7.5% of the soils samples were Mn and Fe deficient or below recommended level. The considered micronutrient concentrations in the grains of wheat were in the acceptable range which are reported globally (range 41.3 and 37.6 mg kg-1 respectively). Furthermore, high application of nitrogen and phosphorus fertilizer in the studied calcareous soils could be strongly affected on the studied micronutrients concentration in the studied grain samples. The results indicate that adequate levels of Mn and Fe in the surveyed grains is a beneficial guide for quality of grains associated with human healthiness, where wheat grain bread is an essential food.
