“…[1][2][3][4] Iron malnutrition is particularly serious in cereal-based developing countries. [5][6][7] Low Fe content in edible parts of plants is the most important reason for Fe deficiency in animals and humans. The target Fe concentration in polished rice, that is the amount needed to have a measurable effect on the Fe status of at-risk people, has been reported to be 14 mg kg −1 .…”

BACKGROUND: In neutral or alkaline soils, iron (Fe) easily forms insoluble complexes, which makes it difficult for plants to utilize Fe in the soil for nutrition. Polyester sulfur-coated urea (PSCU) is a novel controlled-release fertilizer widely used in China and some foreign countries, and it has been proven that sulfur film from controlled-release fertilizers can significantly improve the activation of Fe and other elements in the soil. However, few studies have focused on the effects of PSCU application on Fe accumulation in rice grain in alkaline soils.RESULTS: Both our field and pot experiments proved that PSCU application could significantly improve rice grain yield and Fe concentration in brown rice in alkaline soil. This effect differs with different types of alkaline soils (i.e. medium-saline, sandy soil and/or silt soil). PSCU is released slowly, and the release rate is different in different alkaline soils. Rice shoot nitrogen (N) uptake was significantly enhanced with PSCU application. CONCLUSION:The results suggested that PSCU application in alkaline soils could significantly enhance brown rice Fe concentration and production. This effect differed with different kinds of alkaline soils. The study identified some efficient fertilizers to improve the Fe status in alkaline soils.

“…To this end, the declining cost per data points and ever-increasing throughput of next generation sequencing (NGS) platforms paved the way for rapid and cost-effective development of whole genome sequences in various crops. The biotechnological interventions, in particular the omics tools, are an important part of 'HarvestPlus' (Andersson et al 2014), a global initiative to improve the nutritional status of people (http://www. harvestplus.org/; see Pfeiffer and McClafferty 2007).…”

Meeting the food demands and ensuring nutritional security of the ever increasing global population in the face of degrading natural resource base and impending climate change is the biggest challenge of the twenty first century. The consequences of mineral/micronutrient deficiencies or the hidden hunger in the developing world are indeed alarming and need urgent attention. In addressing the problems associated with mineral/micronutrient deficiency, grain legumes as an integral component of the farming systems in the developing world have to play a crucial role. For resource-poor populations, a strategy based on selecting and/or developing grain legume cultivars with grains denser in micronutrients, by biofortification, seems the most appropriate and attractive approach to address the problem. This is evident from the on-going global research efforts on biofortification to provide nutrient-dense grains for use by the poorest of the poor in the developing countries. Towards this end, rapidly growing genomics technologies hold promise to hasten the progress of breeding nutritious legume crops. In conjunction with the myriad of expansions in genomics, advances in other 'omics' technologies particularly plant ionomics or ionome profiling open up novel opportunities to comprehensively examine the elemental composition and mineral networks of an organism in a rapid and cost-effective manner. These emerging technologies would effectively guide the scientific community to enrich the edible parts of grain legumes with bio-available minerals and enhancers/promoters. We believe that the application of these new-generation tools in turn would provide crop-based solutions to hidden hunger worldwide for achieving global nutritional security.

“…This breeding was typically slow, sometimes limited by availability of desired traits in related species, and often took decades and frequently yielded crop varieties with unforeseen and undesirable properties. More recently, the process evolved to include the use of biotechnological techniques, particularly genetic engineering, to reduce uncertainty and breeding time and to transfer traits from more distantly related species (Andersson et al, 2014 ; James, 2014 ; Sharma et al, 2014 ). Biotechnology encompasses any technique that uses living organisms or substances from such organisms to make or modify a product, to improve plants or animals, or to develop micro-organisms for specific purposes (Masiga et al, 2014 ).…”

The Cartagena Protocol on Biosafety to the Convention on Biological Diversity is an internationally binding instrument addressing issues of biosafety. Biosafety refers to the need to protect human health and the environment from the possible adverse effects of the products of modern biotechnology. Accordingly, all countries to the convention are required to put in place regulatory mechanisms to enhance the safety of biotechnology in the context of the Convention’s overall goal of reducing all potential threats to biological diversity, while taking into account the risks to human health. Therefore, each country party to the convention has its own procedures to enact laws to guide the safe use of biotechnology. In Uganda, the process involves the drafting of the bill by the first parliamentary counsel, approval by cabinet, first reading at the parliament, committal to the responsible parliamentary sessional committee, tabling of the bill for public hearing, consultations, and final approval. In Uganda, the Committee on Science and Technology is responsible for the Biosafety Bill. In March 2013, the Committee tabled the bill for public hearing and submissions from public institutions. There were comments supporting the passage of the Bill and comments in objection. The reasons for objection are mainly due to precaution, speculation, lack of knowledge about biotechnology and biosafety, and alleged influence from biosafety entrepreneurs. This article reviews these public views, revealing controversy and possible consensus to pass the bill.
