ABSTRACT In the face of climate change and increasing problem food security, plant metabolic engineering stands out as most promising approach for improving nutritional quality crops. Techniques used in metabolism innovations being made are helping to improve nutrient staple foods. Through this approach, scientists have been able increase content essential nutrients, such minerals, vitamins, fatty acids, amino help combat malnutrition dietary insufficiency many parts world today. The review highlights genetic biochemical strategies that can be employed management reprogramming pathways synthesize desired nutrients. This includes examples biofortified crops like rice, maize, potatoes, which genetically enhanced contain higher levels nutrients provitamin A, iron, folate. Furthermore, it examines application CRISPR/Cas9 other advanced gene‐editing tools precision breeding nutrition. Moreover, analyzes ensure withstand various environmental stresses exacerbated by change. Combining stress tolerance traits, particularly drought stress, with value is important grown under conditions. synthesizes recent research findings highlight potential enhancing crop It also emphasizes importance adopting multidisciplinary approaches address regulatory, economic, societal challenges field. addresses regulatory approval, public acceptance, ecological impacts. Ultimately, aims inspire further a means bridging gaps security global health well‐being rapidly changing world.

Redox regulation in C₃ and C₄ plants during climate change and its implications on food security

Food and Energy Security, Journal Year: 2022, Volume and Issue: 12(2)

Abstract Achieving food security and sustainable production is a major challenge for plant scientists. To accomplish this, the global needs not only to be remarkably boosted, but it has achieved under harsh environmental conditions. Moreover, climate change scenarios estimate an enhanced pressure on crop yields in upcoming decades. C 4 photosynthesis highly promising meet these challenges production. Under current CO 2 levels, more efficient than 3 photosynthesis, data needed map out its response elevated (eCO ) Growing evidence also suggests that could water use eCO . Production of reactive oxygen species (ROS) inevitable consequence oxygenic one first responses stresses. plants have different ROS profiles, mainly because reduced photorespiration latter. effects especially remain poorly understood. Since patterns, likely signalling downstream growth development differ between plants, which may result This would reflected reproductive success yields. Here we evaluate recent literature conditions from abiotic stress tolerance perspectives, with redox connections. Current body knowledge engineering into crops viable way increase yield, such attempts failed lack basic this area. Therefore, article aims fill gap perspective.

Differential regulation of reactive oxygen species in dimorphic chloroplasts of single cell C4 plant Bienertia sinuspersici during drought and salt stress

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: April 20, 2023

Single cell C4 (SCC4) plants, discovered around two decades ago, are promising materials for efforts genetic engineering of photosynthesis into C3 crops. Unlike plants with Kranz anatomy, they exhibit a fully functional in just single and do not require mesophyll bundle sheath spatial separation. Bienertia sinuspersici is one such SCC4 plant, NAD-malic enzyme (NAD-ME) subtype photosynthesis. Its chlorenchyma consist compartments, peripheral compartment (PC), analogous to cell, central (CC), cell. Since oxidative stress creates an important constraint under salinity drought, we comparatively examined the response enzymatic antioxidant system, H2O2 TBARS contents, peroxiredoxin Q, NADPH thioredoxin reductase C, plastid terminal oxidase protein levels PC chloroplasts (PCC) CC (CCC). Except levels, these parameters were also on whole leaf level, as well catalase activities, water status growth parameters, related transcripts. Many transcript elevated, especially drought. Activities dehydroascorbate peroxidase elevated drought both compartments (CCC PCC). Even though decreases activities more prevalent PCC, redox regulating CCC stresses, PCC was less damaged by either stress. These suggest tolerant has other means preventing or alleviating damage.
