(c) Iron concentration in seeds was increased by expression of CBM‐IBP in Arabidopsis mutant opt3‐2, oligopeptide transporter 3‐2, and Arabidopsis mutant has less iron in seeds than wild type. Values are mean ± SD, n = 3 biological replicates.
The mitochondrial iron regulated (MIR) gene was found to indirectly control Fe concentration in rice seeds (Ishimaru et al., 2009; de Oliveira et al., 2020). Plants that have no functional MIR are unable to properly regulate Fe levels as they accumulate more Fe in roots, shoots, and seeds while having constitutively high expression of Fe uptake ...
Our results indicate that the iron concentration in greenhouse-grown T 2 polished seeds was sixfold higher and that in paddy field-grown T 3 polished seeds was 4.4-fold higher than that in non-transgenic seeds, with no defect in yield. Moreover, the transgenic seeds accumulated zinc up to 1.6-times in the field.
Biofortification (delivery of micronutrients via micronutrient-dense crops) can be achieved through plant breeding and offers a cost-effective and sustainable approach to fighting micronutrient malnutrition. The present study was conducted to facilitate the initiation of a breeding programme to improve the concentration of iron (Fe) and zinc (Zn) in peanut …
To investigate this, we studied the variation in zinc and iron concentrations in seeds of wild and primitive diploid wheats and wild tetraploid wheats. The variation was particularly large in the case of zinc. The highest concentrations of zinc were found in the seeds of ssp. boeoticum (178 mg/kg) and ssp. dicoccoides (159 mg/kg). The results ...
Heavy metals solutions were added during the culture period to maintain seed moist and the concentration of lead and iron. Seeds were treated with FeSO 4 ·7H 2 O (0 or 1.0 g/L) and Pb(NO 3) 2 (0 or 1.0 g/L), thus the four treatments were Fe0Pb0, Fe1Pb0, Fe0Pb1, Fe1Pb1, and are henceforth referred as CK, Fe, Pb, and PbFe, …
Iron (Fe) is an important micronutrient for living organisms. Fe deficiency severely impairs plant growth and is a widespread human dietary problem, with particularly high numbers of affected children and females. Rice (Oryza sativa) is a source of energy for more than half of the world's population. Thus, understanding the mechanisms of Fe …
43 rowsIron is found naturally in many foods such as: Meat, poultry and fish. Eggs. Beans, peas, lentils, tofu. Some vegetables such as spinach and beets. …
Iron concentration ranged from 3.38 ppm to 36.99 ppm and zinc from 3.32 ppm to 42.49 ppm. ... Thus the high priority candidate genes for high Fe and Zn in seeds are OsYSL1 and OsMTP1 for iron ...
The Fe concentration in seeds of osysl2 knockout lines was 37% lower than in WT plants. Strikingly, when OsYSL2 was overexpressed under the control of OsSUT1 promoter, a transporter of sucrose from the phloem to seeds, Fe concentration increased up to 4.4-fold higher than that in WT polished seeds (Ishimaru et al., 2010).
Iron concentration in rice seeds was analyzed using AAS (PerkinElmer S.No 80155070601). About 0.5 g of rice powder was digested with nitric acid and perchloric acid in a ratio of 2:1. After 24 h ...
Mineral nutrients play a crucial role in the biochemical and physiological functions of biological systems. The enhancement of seed mineral content via genetic improvement is considered as the most promising and cost-effective approach compared alternative means for meeting the dietary needs. The overall objective of this study was …
Further, CBM-IBP rice shows a 35% increase in seed iron concentration and a 40% increase in seed yield in greenhouse experiments. In conclusion, CBM-IBP rice potentially could be used to address iron deficiency, the most common and widespread nutritional disorder according to the World Health Organization.} ...
Using the model plant Arabidopsis thaliana, it has been shown that iron is stored during seed development in vacuoles of the endodermis cell layer. During seed …
"Non-heme iron is commonly found in legumes (beans), nuts, seeds and certain vegetables like spinach and potatoes," she continues. You can also get iron …
The third approach is to increase iron concentrations in rice and to enhance iron influx to seeds by expressing the Fe+2- nicotianamine transporter gene OsYSL2.
Iron concentration in seed seems to be lower than in root (p < 0.001), leaf (p < 0.001) and aerial parts (p < 0.001), but no lower than in the whole plant (0.051) or stem (p = 0.087), although, for these two latter categories, there is a relatively strong trend that could be confirmed with higher sample sizes.
However, significantly more iron accumulated in seeds when CBM‐IBP was expressed in the oligopeptide transporter 3‐2 (opt3‐2) mutant background (P < 0.01, Figure 3 c) which has reduced iron concentration in seeds (Stacey et al., 2008).
1. Sesame Seeds. Among nuts and seeds, sesame seeds proudly take their place as a natural source of essential iron, offering a valuable addition to your diet. A …
The present study was conducted to facilitate the initiation of a breeding programme to improve the concentration of iron (Fe) and zinc (Zn) in peanut (Arachis hypogaea L.) seeds. ... protein (150–310 mg/g) and oil (410–610 mg/g) concentration in seeds and their heritability was high, thus indicating the possibility of improving them ...

CBM-IBP rice potentially could be used to address iron deficiency, the most common and widespread nutritional disorder according to the World Health Organization. Introduction
Biofortification efforts to develop bean varieties with seed iron concentrations approaching 90 mg/kg have been underway since the early 2000s. Iron and zinc levels in seeds are positively correlated with each other, and although iron has been the major focus of biofortification efforts, zinc is often evaluated alongside iron.

Lentil (Lens culinaris Medik.) seeds are relatively rich in iron (Fe) and zinc (Zn), making lentil a potential crop to aid in the global battle against human micronutrient deficiency.Understanding the genetic basis for uptake of seed Fe and Zn is required to increase sustainable concentrations of these minerals in seeds.
Iron (Fe) and zinc (Zn) are important micronutrients for human health and well-being. Groundnut kernels are good sources of Fe and Zn. Localization studies of Fe and Zn in the kernel tissues of ten diverse groundnut genotypes revealed that, cotyledons contribute nearly 85–90% of total Fe and Zn in comparison to seed coat and embryo on …
Sesame seeds are by far the highest in iron of all common seeds. They have 14.6 mg in a 100 gram serving, which is about 80% of the RDA for most adult women. Pumpkin seeds, hemp seed, and chia seeds all have around 7-9 mg of iron per serving, which is about 40-50% of the RDA.
