Manganese (Mn) is an important micronutrient for plant growth and development sustains metabolic roles within different cell compartments. The metal essential cofactor the oxygen-evolving complex of photosynthetic machinery, catalyzing water-splitting reaction in photosystem II (PSII). Despite importance Mn photosynthesis other processes, physiological relevance uptake compartmentation plants has been underrated. subcellular homeostasis to maintain compartmented Mn-dependent processes like glycosylation, ROS scavenging, mediated by a multitude transport proteins from diverse gene families. However, may be disturbed under suboptimal or excessive availability. deficiency serious, widespread nutritional disorder dry, well-aerated calcareous soils, as well soils containing high amounts organic matter, where bio-availability can decrease far below level that required normal growth. By contrast, toxicity occurs on poorly drained acidic which are rendered available. Consequently, have evolved mechanisms tightly regulate uptake, trafficking, storage. This review provides comprehensive overview, with focus recent advances, multiple functions transporters involved homeostasis, their regulatory plant's response conditions

Zinc (Zn), which is regarded as a crucial micronutrient for plants, and considered to be vital plants. Zn has significant role in the biochemistry metabolism of plants owing its significance toxicity biological systems at specific concentrations, i.e., insufficient or harmful above optimal range. It contributes several cellular physiological activities promotes plant growth, development, yield. an important structural, enzymatic, regulatory component many proteins enzymes. Consequently, it essential understand interplay chemistry soil, absorption, transport, response deficiency, well develop sustainable strategies deficiency appears widespread prevalent issue crops across world, resulting severe production losses that compromise nutritional quality. Considering this, enhancing usage efficiency most effective strategy, entails improving architecture root system, absorption complexes by organic acids, uptake translocation mechanisms Here, we provide overview various biotechnological techniques improve utilization ensure quality crop. In light current status, effort been made further dissect assimilation, function, symptoms caused As result, have described potential information on diverse solutions, such structure alteration, use biostimulators, nanomaterials, may used efficiently uptake, thereby assuring agriculture.

Molecular mechanisms underlying the toxicity and detoxification of trace metals and metalloids in plants

Journal of Integrative Plant Biology, Год журнала: 2022, Номер 65(2), С. 570 - 593

Опубликована: Дек. 22, 2022

Abstract Plants take up a wide range of trace metals/metalloids (hereinafter referred to as metals) from the soil, some which are essential but become toxic at high concentrations (e.g., Cu, Zn, Ni, Co), while others non‐essential and even relatively low As, Cd, Cr, Pb, Hg). Soil contamination metals is an increasing problem worldwide due intensifying human activities. Trace metal can cause toxicity growth inhibition in plants, well accumulation edible parts levels that threatens food safety health. Understanding mechanisms how plants respond stress important for improving plant contaminated soils. The excess oxidative stress, genotoxicity, programmed cell death, disturbance multiple physiological processes. have evolved various strategies detoxify through cell‐wall binding, complexation, vacuolar sequestration, efflux, translocation. Multiple signal transduction pathways regulatory responses involved challenged with stresses. In this review, we discuss recent progress understanding molecular toxicity, detoxification, regulation, enhance resistance stresses reduce crops.

Microbial enhancement of plant nutrient acquisition

Stress Biology, Год журнала: 2022, Номер 2(1)

Опубликована: Янв. 10, 2022

Nutrient availability is a determining factor for crop yield and quality. While fertilization major approach improving plant nutrition, its efficacy can be limited the production application of fertilizers frequently bring problems to environment. A large number soil microbes are capable enhancing nutrient acquisition thereby offer environmentally benign solutions meet requirements nutrition. Herein we provide summations how beneficial enhance macronutrients micronutrients. We also review recent studies on nutrition-dependent plant-microbe interactions, which highlight plant's initiative in establishing or deterring association. By dissecting complex signaling interactions between within root microbiome, greater understanding microbe-enhanced nutrition under specific biotic abiotic stresses will possible.

Micronutrient homeostasis in plants for more sustainable agriculture and healthier human nutrition

Journal of Experimental Botany, Год журнала: 2022, Номер 73(6), С. 1789 - 1799

Опубликована: Янв. 28, 2022

The provision of sustainable, sufficient, and nutritious food to the growing population is a major challenge for agriculture plant research community. In this respect, mineral micronutrient content crops deserves particular attention. Micronutrient deficiencies in cultivated soils plants are global problem that adversely affects crop production nutritional value, as well human health well-being. review, we call awareness importance relevance micronutrients quality. We stress need better nutrition populations, not only developing but also developed nations, describe strategies identify characterize new varieties with high content. Furthermore, explain how adequate impacts metabolic functions capacity express tolerance mechanisms against abiotic biotic constraints. Finally, provide brief overview critical discussion on current knowledge, future challenges, specific technological needs homeostasis. Research area expected foster sustainable development healthy consumption.

Phytochelatins: Sulfur-Containing Metal(loid)-Chelating Ligands in Plants

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(3), С. 2430 - 2430

Опубликована: Янв. 26, 2023

Phytochelatins (PCs) are small cysteine-rich peptides capable of binding metal(loid)s via SH-groups. Although the biosynthesis PCs can be induced in vivo by various metal(loid)s, mainly involved detoxification cadmium and arsenic (III), as well mercury, zinc, lead, copper ions, which have high affinities for S-containing ligands. The present review provides a comprehensive account recent data on PC biosynthesis, structure, role metal(loid) transport sequestration vacuoles plant cells. A comparative analysis accumulation hyperaccumulator plants, accumulate their shoots, excluders, roots, investigates question whether endogenous concentration determines plant's tolerance to metal(loid)s. Summarizing available data, it concluded that not hyperaccumulation machinery, though they play key homeostasis. Unraveling physiological metal(loid)-binding ligands is fundamental problem modern molecular biology, physiology, ionomics, toxicology, important development technologies used phytoremediation, biofortification, phytomining.
