Current global agricultural production must feed over 7 billion people. However, productivity varies greatly across the globe and is under threat from both increased competitions for land climate change associated environmental deterioration. Moreover, increase in human population size dietary changes are putting an ever greater burden on agriculture. The majority of this met by cultivation a very small number species, largely locations that differ their origin domestication. Recent technological advances have raised possibility de novo domestication wild plants as viable solution designing ideal crops while maintaining food security more sustainable low-input Here we discuss how discovery multiple key genes alongside development technologies accurate manipulation several target simultaneously renders route toward future.

Global climate is changing more rapidly than ever, threatening plant growth and productivity while exerting considerable direct indirect effects on the quality quantity of nutrients. This review focuses global impact change nutritional value foods. It showcases existing evidence linking factors crop nutrition concentration nutrients in edible parts. effect elevated CO2 (eCO2), temperature (eT), salinity, waterlogging drought stresses, what known regarding their influence nutrient availability. Furthermore, it provides possible strategies to preserve composition foods under climates. Climate has an accumulation minerals protein plants, with eCO2 being underlying factor most reported changes. The are clearly dependent type, intensity duration imposed stress, genotype developmental stage. Strong interactions (both positive negative) can be found between individual climatic soil availability nitrogen (N), potassium (K), iron (Fe) phosphorous (P). development future interventions ensure that world's population access plentiful, safe nutritious food may need rely breeding for context change, including legumes cropping systems, better farm management practices utilization microbial inoculants enhance

Wheat Vacuolar Iron Transporter TaVIT2 Transports Fe and Mn and Is Effective for Biofortification

PLANT PHYSIOLOGY, Год журнала: 2017, Номер 174(4), С. 2434 - 2444

Опубликована: Июль 6, 2017

Increasing the intrinsic nutritional quality of crops, known as biofortification, is viewed a sustainable approach to alleviate micronutrient deficiencies. In particular, iron deficiency anemia major global health issue, but content staple crops such wheat (Triticum aestivum) difficult change because genetic complexity and homeostasis mechanisms. To identify target genes for biofortification wheat, we functionally characterized homologs VACUOLAR IRON TRANSPORTER (VIT). The genome contains two VIT paralogs, TaVIT1 TaVIT2, which have different expression patterns are both low in endosperm. not TaVIT1, was able rescue growth yeast (Saccharomyces cerevisiae) mutant defective vacuolar transport. TaVIT2 also complemented manganese transporter zinc mutant. By overexpressing under control an endosperm-specific promoter, achieved greater than 2-fold increase white flour fractions, exceeding minimum legal fortification levels countries United Kingdom. antinutrient phytate increased fraction bioavailable vitro, suggesting that food products made from biofortified could contribute improved nutrition. single-gene impacted minimally on plant effective barley (Hordeum vulgare). Our results show by enhancing transport endosperm, this essential accumulated tissue, bypassing existing homeostatic

Designing future crops: challenges and strategies for sustainable agriculture

The Plant Journal, Год журнала: 2020, Номер 105(5), С. 1165 - 1178

Опубликована: Дек. 1, 2020

Summary Crop production is facing unprecedented challenges. Despite the fact that food supply has significantly increased over past half‐century, ~8.9 and 14.3% people are still suffering from hunger malnutrition, respectively. Agricultural environments continuously threatened by a booming world population, shortage of arable land, rapid changes in climate. To ensure ecosystem security, there need to design future crops for sustainable agriculture development maximizing net minimalizing undesirable effects on environment. The projects, recently launched National Natural Science Foundation China Chinese Academy Sciences (CAS), aim develop roadmap customized using cutting‐edge technologies Breeding 4.0 era. In this perspective, we first introduce background missions these projects. We then outline strategies crops, such as improvement current well‐cultivated de novo domestication wild species redomestication cultivated crops. further discuss how ambitious goals can be achieved recent new integrative omics tools, advanced genome‐editing tools synthetic biology approaches. Finally, summarize related opportunities challenges

Iron Biofortification of Staple Crops: Lessons and Challenges in Plant Genetics

Plant and Cell Physiology, Год журнала: 2019, Номер 60(7), С. 1447 - 1456

Опубликована: Апрель 23, 2019

Abstract Plants are the ultimate source of iron in our diet, either directly as staple crops and vegetables or indirectly via animal fodder. Increasing concentration edible parts plants, known biofortification, is seen a sustainable approach to alleviate deficiency which major global health issue. Advances sequencing gene technology accelerating both forward reverse genetic approaches. In this review, we summarize recent progress biofortification using conventional plant breeding transgenics. Interestingly, some targets already used for transgenic approaches also identified factors high genome-wide association studies. Several quantitative trait loci transgenes increase zinc, due overlap transporters chelators these two mineral micronutrients. Research efforts predominantly aimed at increasing total but enhancing its bioavailability addressed. particular, increased biosynthesis metal chelator nicotianamine increases zinc levels improves bioavailability. The achievements date very promising being able provide sufficient diets with less reliance on meat feed growing world population.

Опубликована: Фев. 17, 2022

Abstract Biofortification is a long-term strategy of delivering more iron (Fe) and zinc (Zn) to those most in need. Plant breeding programs within the CGIAR NARS have made major advances Fe- Zn-dense variety development there been successful releases new biofortified varieties. Recent research effort has led substantial improvement our knowledge Fe Zn homeostasis gene regulation, resulting identification candidate genes for marker assisted selection. International cooperation between agricultural nutrition community strengthened, with numerous implementation partnership strategies developed employed over years. The evidence on effectiveness crops slowly building up results are encouraging. continues be scaled out further work required reach general aim eradicating hidden hunger deficiency world’s population ensuring nutritional security.

An Alarming Decline in the Nutritional Quality of Foods: The Biggest Challenge for Future Generations’ Health

Foods, Год журнала: 2024, Номер 13(6), С. 877 - 877

Опубликована: Март 14, 2024

In the last sixty years, there has been an alarming decline in food quality and a decrease wide variety of nutritionally essential minerals nutraceutical compounds imperative fruits, vegetables, crops. The potential causes behind nutritional foods have identified worldwide as chaotic mineral nutrient application, preference for less nutritious cultivars/crops, use high-yielding varieties, agronomic issues associated with shift from natural farming to chemical farming. Likewise, rise atmospheric or synthetically elevated carbon dioxide could contribute extensive reductions Since ancient times, nutrient-intense crops such millets, conventional vegetables broadly grown are most important staple food, but area dedicated these declining steadily over past few decades hastily after green revolution era due their poorer economic competitiveness major commodities varieties potato, tomato, maize, wheat, rice. majority population underdeveloped developing countries lower immune systems, severely malnourished, multiple deficiency disorders poor dietary intake because ignorance about importance our traditional nutrient-rich diets ecofriendly organic methods. This critical review emphasizes balance adequate nutrition well need improve soil biodiversity fertility: those main density. There is also emphasis on possible way out alleviating density health well-being future generations.
