“…An overexpression of soybean ferritin gene Soyfer H-1 gene resulted in an increase of Fe contents to as high as 38.1 µg Fe/g of DW, Phaseolus ferritin improving iron concentration to 22.07 µg Fe/g DW, Osfer2 to 7.0 µg/g DW, while OsNAS2 increased it to 19 µg/g DW (114). 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).…”

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.

“…There have been a number of excellent recent reviews describing Fe and Zn metabolism and translocation in plants, together with the associated regulatory mechanisms (Balafrej et al, 2020 ; Curie & Mari, 2017 ; Dey et al, 2020 ; Gao & Dubos, 2021 ; Rai et al, 2021 ; Ram et al, 2021 ; Rehman et al, 2021 ; Sperotto et al, 2018 ; Whitt et al, 2020 ; Yadav et al, 2021 ). Such reviews often focus on cereal crops such as wheat, rice and barley (Detterbeck et al, 2020 ; Huang et al, 2020 ; Pandit et al, 2021 ; Pradhan et al, 2020 ; Xia et al, 2020 ). Despite this extensive knowledge, relatively little information is available on these processes in legumes, particularly common bean.…”

Micronutrient deficiencies (hidden hunger), particularly in iron (Fe) and zinc (Zn), remain one of the most serious public health challenges, affecting more than three billion people globally. A number of strategies are used to ameliorate the problem of micronutrient deficiencies and to improve the nutritional profile of food products. These include (i) dietary diversification, (ii) industrial food fortification and supplements, (iii) agronomic approaches including soil mineral fertilisation, bioinoculants and crop rotations, and (iv) biofortification through the implementation of biotechnology including gene editing and plant breeding.These efforts must consider the dietary patterns and culinary preferences of the consumer and stakeholder acceptance of new biofortified varieties. Deficiencies in Zn and Fe are often linked to the poor nutritional status of agricultural soils, resulting in low amounts and/or poor availability of these nutrients in staple food crops such as common bean. This review describes the genes and processes associated with Fe and Zn accumulation in common bean, a significant food source in Africa that plays an important role in nutritional security. We discuss the conventional plant breeding, transgenic and gene editing approaches that are being deployed to improve Fe and Zn accumulation in beans. We also consider the requirements of successful bean biofortification programmes, highlighting gaps in current knowledge, possible solutions and future perspectives.
