FIGURE 2. Iron localization in seeds. (A) In rice, the concentration of Fe is highest in the aleurone layer, the integument, and the scutellum. Iron levels are also high in the hull. In the starchy endosperm the Fe content is low. (B) In Arabidopsis, Fe is mainly localized in vacuoles of endodermal cells that surround provascular tissues, whereas in other cells the Fe concentration is ...

1-1-2000· 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 increased chlorophyll concentration in the CBM‐IBP flag leaves is consistent with increased seed yield and iron concentrations in biomass and seeds (described below). Rice tillering is modulated by strigolactones, and DWARF 27 (D27), an iron‐binding isomerase that converts trans ‐β‐carotene into 9‐ cis ‐β‐carotene in the strigolactone biosynthetic pathway (Alder et al ...

The highest concentrations of zinc were found in the seeds of ssp. boeoticum (178 mg/kg) and ssp. dicoccoides (159 mg/kg). The results demonstrate that the genetic variation in the concentrations of zinc and iron in cultivated modern tetraploid and hexaploid wheats is extremely low when compared with the variation found in wild diploid and tetraploid wheats.

The extremes of seed Fe concentration were found within the imported germplasm (minimum: ILL 2607 from India; maximum: PI 299215 from Chile) (Supplemental Table S1D). Less variation was observed within the entire germplasm set for seed Zn concentration compared with that for Fe.

Genetic dissection of seed-iron and zinc concentrations in ...

Significant QTLs associated with seed-iron and zinc concentrations identified and mapped on the chromosomes of a high-density intra-specific chickpea genetic linkage map (ICC 4958 × ICC 8261). For seed-Fe concentration, three major genomic regions harbouring three robust QTLs (21.1–23.4% PVE with 8.0–8.8 LOD) were mapped on three chromosomes (1, 3 and 4) ( Table 2 , Fig. 2 ).

Iron deficiency currently affects over two billion people worldwide despite significant advances in technology and society aimed at mitigating this global health problem. Biofortification of food staples with iron (Fe) represents a sustainable approach for alleviating human Fe deficiency in developing countries, however, biofortification efforts have focused extensively on cereal staples while ...

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.

SEEDS II was carried out at almost the same location, the same season and the same protocol to manipulate the iron concentration as SEEDS. However, the magnitude of the iron-induced phytoplankton bloom was quite different between SEEDS and SEEDS II, with a significantly lower response in SEEDS II (Tsuda et al., 2007).

Iron and Zn deficiencies are worldwide nutritional disorders that can be alleviated by increasing the metal concentration of rice (Oryza sativa L.) grains via bio-fortification approaches. The overproduction of the metal chelator nicotianamine (NA) is among the most effective ones, but it is still unclear whether this is due to the enrichment in NA itself and/or the concomitant enrichment in ...

Iron fertilization - Wikipedia

Iron fertilization is the intentional introduction of iron to iron-poor areas of the ocean surface to stimulate phytoplankton production. This is intended to enhance biological productivity and/or accelerate carbon dioxide (CO 2) sequestration from the atmosphere.. Iron is a trace element necessary for photosynthesis in plants. It is highly insoluble in sea water and in a variety of locations ...
