“…Although differences in soil water management and soil pH could partially explain the difference in Zn accumulation in grain among sites, other factors such as chemical availability in the rhizosphere induced by plant roots and the increased acquisitions area by root growth or mycorrhizae are known to impact Zn acquisition by plants ( Gao et al, 2012 ). Saenchai et al (2016) reported up to 6 µg.g −1 higher zinc concentration in rice cultivated in soils with high Zn availability compared to rice cultivated in soils with low Zn availability. Mayer et al (2008) observed that Zn concentration in brown rice produced under soils with low Zn availability in Bangladesh was 18.6 µg.g −1 in the irrigated season and 20.8 µg.g −1 in monsoon season, similar to the Zn levels in NPBDOM0 produced in Palmira.…”

“…Translocation and accumulation of Fe and Zn into the rice grain, however, can differ from those in the vegetative plant parts. For nonpigmented or white rice, wetland culture produced unpolished rice with higher Zn concentration than aerobic culture, while the water regime had no effect on the grain Fe (Saenchai et al, 2016), the higher availability of Fe and lower availability of Zn in wetland soil notwithstanding. The concentration of grain Zn and Fe in Thailand's mega varieties such as KDML105, RD6 and PPT1 grown under wetland conditions as their original ecotype was ranged from 17.3 to 25.8 mg Zn kg −1 and 6.3 to 14.1 mg Fe kg −1 in unpolished grain (Saenchai et al, 2012).…”

This study evaluated grain anthocyanin, zinc (Zn) and iron (Fe) concentrations, and grain yield of eleven purple rice varieties (PP1-PP11) grown under wetland (W+) and aerobic conditions (W0) in 2 years. There was a significant variation in the concentrations of anthocyanin, Zn and Fe, by water regime and year among the varieties with a wide range of anthocyanin (1-117 mg 100 g −1) and narrower ranges of Zn (19-41 mg kg −1) and Fe (6-19 mg kg −1) concentrations. The nutritional quality in aerobic grown rice was lower than wetland grown among the varieties with higher levels of anthocyanin (>40 mg 100 g −1), Zn (>30 mg kg −1) and Fe (>15 mg kg −1), with smaller effects of water among varieties in the lower quality ranges. The lowering of anthocyanin in aerobic grown rice was observed in the two varieties of the upland ecotype that were highest in anthocyanin concentration, as well as some wetland varieties. The grain yield (1.4-6.7 Mg ha −1) was associated negatively with grain Zn concentration (r = −0.50, P ≤ 0.001), but not with grain Fe (r = −0.14, NS 0.05) or anthocyanin (r = −0.27, NS 0.05). The anthocyanin concentration in the purple rice increased with Zn concentration (r = 0.57, P ≤ 0.001). Wetland condition was shown to be more favorable than aerobic culture for intense pigmentation in the production of purple rice, as well as higher Zn and Fe concentrations.

“…Fe in cereal is stored in vacuoles in complex with phytate (Borg et al, 2012), and localized in the aleurone layer and embryo parts. Minimal phytate amount has been detected in the endosperm (Saenchai et al, 2016). Depending on the genotype, the rice bran can have one to five aleurone layers (Del Rosario et al, 1968).…”

The micronutrient iron (Fe) is not only essential for plant survival and proliferation but also crucial for healthy human growth and development. Rice and wheat are the two leading staples globally; unfortunately, popular rice and wheat cultivars only have a minuscule amount of Fe content and mainly present in the outer bran layers. Unavailability of considerable Fe-rich rice and wheat germplasms limits the potential of conventional breeding to develop this micronutrient trait in both staples. Agronomic biofortification, defined as soil and foliar fertilizer application, has potential but remains quite challenging to improve grain Fe to the significant level. In contrast, recent accomplishments in genetic biofortification can help to develop Fe-enriched cereal grains to sustainably address the problem of “hidden hunger” when the roadmap from proof of concept to product and adoption can be achieved. Here, we highlight the different genetic biofortification strategies for rice and wheat and path to develop a product.
