Food and Energy Security, Journal Year: 2022, Volume and Issue: 12(1)

Published: Nov. 25, 2022

Abstract Environmental stresses including salinity, drought, cold, warmer temperatures, alterations in precipitation patterns, fluctuations of weather events, and increasing insect disease infestations negatively affect crop production nutritional values. This situation becomes further complicated due to the changing climatic conditions, thus raising concern about food security worldwide. Some worst‐case projections indicated that by 2100, CO 2 concentrations will reach 950 parts per million, temperatures climb 3.5 more than 8°C, sea level rise 2.4 meters, average farmland drought risk index increase from 52.45 129. In addition, 1%–3% some areas atmospheric water vapor 6%–7% for every degree temperature rise. Rice ( Oryza sativa L.) is a staple many world. The main objective this review highlight prospects rice future conditions. present depicts advantages addresses why better option as cereal situations sustainability. impact climate change on can be mitigated developing biotic abiotic stress‐tolerant biofortified varieties. These cultivars withstand negative effects while also meeting needs generations. Furthermore, underlines forthcoming issues measures should addressed assure sustainable supply era global change.

Current Status and Potential of Biofortification to Enhance Crop Nutritional Quality: An Overview

Sustainability, Journal Year: 2022, Volume and Issue: 14(6), P. 3301 - 3301

Published: March 11, 2022

Around 2 billion people are suffering from chronic malnutrition or “hidden hunger”, which is the result of many diseases and disorders, including cognitive degeneration, stunting growth, mortality. Thus, biofortification staple food crops enriched with micronutrients a more sustainable option for providing nutritional supplements managing in society. Since 2001, when concept came to light, different research activities have been carried out, like development target populations, breeding genetic engineering, release biofortified cultivars, addition conducting efficacy trials delivery plan development. Although, being cost-effective intervention, it still faces challenges, easy accessibility stakeholders’ acceptance, availability germplasm public domain, varies region region. Hence, this review focused on recent potential, efforts made crop biofortification, impacts analysis human health, cost-effectiveness, future perspectives further strengthen programs. Through regular interventions techniques methodologies, holds huge potential solve problem through nutrient-enriched options billions globally.

Biofortification of major crop plants with iron and zinc - achievements and future directions

Plant and Soil, Journal Year: 2022, Volume and Issue: 474(1-2), P. 57 - 76

Published: Feb. 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.

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.

The Potential of High-Anthocyanin Purple Rice as a Functional Ingredient in Human Health

Antioxidants, Journal Year: 2021, Volume and Issue: 10(6), P. 833 - 833

Published: May 24, 2021

Purple rice is recognized as a source of natural anthocyanin compounds among health-conscious consumers who employ their staple food. Anthocyanin one the major antioxidant that protect against reactive oxygen species (ROS) cause cellular damage in plants and animals, including humans. The physiological role not fully understood, but benefits to human health are apparent both chronic non-chronic diseases. This review focuses on synthesis accumulation whole plant purple rice, from cultivation processed end products. content varies due many factors, genotype, cultivation, management well post-harvest processing. method strongly influences plants; water conditions, light quantity quality, available nutrients soil important while low stability anthocyanins means they can be dramatically degraded under high-temperature conditions. application has been developed functional food other purposes. To maximize health, understanding factors influencing during entire process product development path for success.
