“…Moreover, overexpression of ferritin under control of endosperm-specific promoters' globulinb 1 (OsGlb 1 ) and glutelin B 1 (OsGluB 1 ), NAS with control of OsActin1 promoter and OsYSL2 along with OsGlb 1 and OsSUT 1 transport promoters resulted in iron biofortification in polished rice (115). Similarly, zinc biofortification with HvIDS3, HvNAAT-A, HvNAAT-B, and HvNAS1 genes resulted in 35 µg Zn/g of DW (58), soybean ferritin, Aspergillus flavus phytase, OsNAS1 exhibited 35 µg Zn/g of DW, while overexpression of OsNAS2 resulted in 76 µg Zn/g of DW in rice crop (11). Another study highlighted the biofortification of endogenous rice lysine-rich histone proteins by overexpression of RLRH 1 and RLRH 2 with modified rice glutelin1 promoter.…”

“…(Continued) focus on cultivar improvement in terms of micronutrient accumulation, bioavailability, and suppression of anti-nutrients (Box 1) (10). Biofortification was initially designed to overcome the drawbacks and deficiencies of supplementation (11). Therefore, a modern weapon against mineral deficiency involved transferring the genes directly in elite genotypes.…”

Biofortification of Cereals and Pulses Using New Breeding Techniques: Current and Future Perspectives

Cereals and pulses are consumed as a staple food in low-income countries for the fulfillment of daily dietary requirements and as a source of micronutrients. However, they are failing to offer balanced nutrition due to deficiencies of some essential compounds, macronutrients, and micronutrients, i.e., cereals are deficient in iron, zinc, some essential amino acids, and quality proteins. Meanwhile, the pulses are rich in anti-nutrient compounds that restrict the bioavailability of micronutrients. As a result, the population is suffering from malnutrition and resultantly different diseases, i.e., anemia, beriberi, pellagra, night blindness, rickets, and scurvy are common in the society. These facts highlight the need for the biofortification of cereals and pulses for the provision of balanced diets to masses and reduction of malnutrition. Biofortification of crops may be achieved through conventional approaches or new breeding techniques (NBTs). Conventional approaches for biofortification cover mineral fertilization through foliar or soil application, microbe-mediated enhanced uptake of nutrients, and conventional crossing of plants to obtain the desired combination of genes for balanced nutrient uptake and bioavailability. Whereas, NBTs rely on gene silencing, gene editing, overexpression, and gene transfer from other species for the acquisition of balanced nutritional profiles in mutant plants. Thus, we have highlighted the significance of conventional and NBTs for the biofortification of cereals and pulses. Current and future perspectives and opportunities are also discussed. Further, the regulatory aspects of newly developed biofortified transgenic and/or non-transgenic crop varieties via NBTs are also presented.

“…To overcome the challenge of Zn deficiency, agronomic biofortification of Zn could be a possible solution (Zulfiqar, Hussain, et al., 2020; Zulfiqar, Maqsood, & Hussain, 2020), in which Zn can be applied through various methods including basal application, foliar spray, seed coating, and seed priming (Ullah, Farooq, & Hussain, 2019); however, variations exist among different methods regarding cost effectiveness and efficacy (Zulfiqar, Maqsood, Hussain, & Anwar‐ul‐Haq, 2020).…”

Zinc (Zn) deficiency is the most important abiotic factor limiting rice (Oryza sativa L.) productivity and also a nutritional disorder with adverse impacts on human health worldwide. The present study investigated the comparative effect of four Zn application methods: Zn seed coating (2 g Zn kg−1 seed), Zn seed priming (0.25 M Zn solution), basal application (10 kg ha−1), and Zn foliar spray (0.5% Zn solution) in improving the productivity and biofortification of rice under puddled transplanted (PudTR) and direct‐seeded rice (DSR) system. A general control with no Zn application was included, whereas hydro‐priming and foliar water application were used as positive control treatments for Zn seed priming and Zn foliar spray, respectively. Regardless of application methods, Zn nutrition significantly improved the yield and related traits and grain Zn concentration in both production systems. Averaged across 2 yr, the increase in grain yield under different Zn application treatments was in the order of seed priming (23%) > foliar application (18%) > basal application (18%) > seed coating (13%), compared with the control. However, grain Zn concentration was the highest with seed priming in PudTR (33% over control) and with basal application in DSR (45% over control). The maximum net benefits were obtained through Zn seed priming in both production systems. In conclusion, Zn seed priming improved the yield and was the most cost‐effective method in PudTR and DSR system.
