Globally, many developing countries are facing silent epidemics of nutritional deficiencies in human beings and animals. The lack diversity diet, i.e., cereal-based crops deficient mineral nutrients is an additional threat to quality. present review accounts for the significance biofortification as a process enhance productivity also agricultural solution address issues security. In this endeavor, different innovative specific approaches have been discussed nutrient enrichment field including cereals, pulses, oilseeds fodder crops. agronomic approach increases micronutrient density with soil foliar application fertilizers amendments. through conventional breeding includes selection efficient genotypes, practicing crossing plants desirable traits without sacrificing economic productivity. However, transgenic/biotechnological involves synthesis transgenes re-translocation between tissues their bioavailability. Soil microorganisms content rhizosphere diverse mechanisms such synthesis, mobilization, transformations siderophore production which accumulate more minerals plants. Different sources micronutrients viz. solutions, chelates nanoparticles play pivotal role it regulates absorption rates Apart from quality parameters, improved crop yield alleviate hidden hunger thus proving be sustainable cost-effective approach. Thus, article conveys message researchers about adequate potential increase nourish provide food security humans livestock.

Agronomic Biofortification with Se, Zn, and Fe: An Effective Strategy to Enhance Crop Nutritional Quality and Stress Defense—A Review

Journal of soil science and plant nutrition, Journal Year: 2021, Volume and Issue: 22(1), P. 1129 - 1159

Published: Dec. 3, 2021

Abstract Human micronutrient deficiencies are a widespread problem worldwide and mainly concern people whose diet (mainly of plant origin) consists insufficient amounts critical vitamins minerals. Low levels micronutrients in plants linked to, i.e., their decreasing concentration soils and/or low bioavailability presence abiotic stresses which disturb the proper growth development plants. Agronomic biofortification crops is very promising way to improve edible parts without compromising yield recognized as cheapest strategy alleviate hidden hunger worldwide. The review focused on factors influencing effectiveness biofortified (a type application, form, dose applied microelement, biofertilizers, nanofertilizers). Also, accumulation zinc, selenium, iron crops, effects metabolism, morphological parameters, an impact plants’ defense mechanisms against stress like salt, high/low temperature, heavy metal, drought was discussed. Finally, directions future agronomic studies proposed.

Mechanistic Impact of Zinc Deficiency in Human Development

Frontiers in Nutrition, Journal Year: 2022, Volume and Issue: 9

Published: March 9, 2022

Zinc (Zn) deficiency in humans is an emerging global health issue affecting approximately two billion people across the globe. The situation prevails due to intake of Zn deficient grains and vegetables worldwide. Clinical identification remains problematic because symptoms do not appear until impair vital organs, such as gastrointestinal track, central nervous system, immune skeletal, system. Lower body levels are also responsible for multiple physiological disorders, apoptosis, organs destruction, DNA injuries, oxidative damage cellular components through reactive oxygen species (ROS). causes chronic inflammation lead toward several diseases, heart cancers, alcohol-related malady, muscular contraction, neuro-pathogenesis. present review focused on growth-related changes under conditions, mechanisms adopted by human proper functioning systems, importance nutritional nutraceutical approaches overcome concluded that biofortified food best source compared chemical supplementation avoid their negative impacts human.

Biofortification: an approach to eradicate micronutrient deficiency

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: Sept. 14, 2023

Micronutrient deficiency also known as "hidden hunger" refers to a condition that occurs when the body lacks essential vitamins and minerals are required in small amounts for proper growth, development overall health. These deficiencies particularly common developing countries, where lack of access varied nutritious diet makes it difficult people get micronutrients they need. supplementation has been topic interest, especially during Covid-19 pandemic, due its potential role supporting immune function Iron (Fe), zinc (Zn), iodine (I), selenium (Se) humans significant food-related issues worldwide. Biofortification is sustainable strategy developed address micronutrient by increasing levels staple crops widely consumed affected communities. There number agricultural techniques biofortification, including selective breeding have higher specific nutrients, agronomic approach using fertilizers other inputs increase nutrient uptake transgenic approach. The offers temporary but speedy solution while genetic (breeding transgenic) long-term requires time develop nutrient-rich variety.

Making wheat salt tolerant: What is missing?

The Crop Journal, Journal Year: 2024, Volume and Issue: 12(5), P. 1299 - 1308

Published: Feb. 3, 2024

The growing global population presents a significant challenge to ensuring food security, further compounded by the increasing threat of salinity agricultural productivity. Wheat, major staple providing 20 % total caloric intake for humans, is susceptible stress. Developing new salt-tolerant wheat cultivars using breeding techniques and genetic modifications crucial addressing this issue while sustainability efficiency production systems within prevailing climate trend. This review overviews current landscape in field explores key mechanisms associated traits that warrant attention programs. We contend traditional approaches Na+ exclusion have limited applicability across varying soil levels, rendering them inefficient. Moreover, we question phenotyping approaches, advocating shift from whole-plant assessments cell-based platforms. Finally, propose broader use wild relatives various strategies tap into their germplasm pool inclusion

Abstract Zinc deficiency, being the fifth leading risk factor for diseases is associated with several disorders and infections, especially diarrhea. The common strategies sustaining zinc's bioavailability include food fortification, biofortification, supplementation, dietary diversification. To obtain best technique, we need to appraise ourselves of causes zinc modalities, potential enhancers as well inhibitors. This review highlights role in human health, its bioavailability, consequences alleviate deficiency. strategy supplementation pertinent, mostly population whom usual diet insufficient replenishment, a short period, status has be enhanced. For high‐risk groups, fortification could targeted prevent potent inhibitors from hindering absorption. By enhancement concentration can obtained edible portion plants. Germination, fermentation, addition enhancers, other processing techniques also help increase Dietary modification found an economically feasible, equitable, sustainable strategy, used mitigate deficiencies without any antagonistic effect. These should integrated health nutrition programs create awareness education, enhance their sustainability effectiveness.
