Опубликована: Март 26, 2020

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

Trace metal metabolism in plants

Journal of Experimental Botany, Год журнала: 2017, Номер 69(5), С. 909 - 954

Опубликована: Дек. 13, 2017

Many trace metals are essential micronutrients, but also potent toxins. Due to natural and anthropogenic causes, vastly different metal concentrations occur in various habitats, ranging from deficient toxic levels. Therefore, one focus of plant research is on the response terms uptake, transport, sequestration, speciation, physiological use, deficiency, toxicity, detoxification. In this review, we cover most these aspects for micronutrients copper, iron, manganese, molybdenum, nickel, zinc provide a broader overview than found other recent reviews, cross-link knowledge very active field that often seen separated way. For example, individual processes usage, or toxicity were not mechanistically interconnected. review aims stimulate communication researchers following approaches, such as gene expression analysis, biochemistry, biophysics metalloproteins. Furthermore, highlight insights, emphasizing data obtained under physiologically environmentally relevant conditions.

Advances in the Mechanisms of Plant Tolerance to Manganese Toxicity

International Journal of Molecular Sciences, Год журнала: 2019, Номер 20(20), С. 5096 - 5096

Опубликована: Окт. 14, 2019

Manganese (Mn) is an essential element for plant growth due to its participation in a series of physiological and metabolic processes. Mn also considered heavy metal that causes phytotoxicity when present excess, disrupting photosynthesis enzyme activity plants. Thus, toxicity major constraint limiting production, especially acid soils. To cope with toxicity, plants have evolved wide range adaptive strategies improve their under this stress. tolerance mechanisms include activation the antioxidant system, regulation uptake homeostasis, compartmentalization into subcellular compartments (e.g., vacuoles, endoplasmic reticulum, Golgi apparatus, cell walls). In regard, numerous genes are involved specific pathways controlling detoxification. Here, we summarize recent advances highlight roles responsible uptake, translocation, distribution, contributing We hope review will provide comprehensive understanding through gene regulation, which aid breeding crop varieties via genetic improvement approaches, enhancing yield quality crops.

Micronutrients and their effects on Horticultural crop quality, productivity and sustainability

Scientia Horticulturae, Год журнала: 2023, Номер 323, С. 112512 - 112512

Опубликована: Окт. 13, 2023

Horticultural crop quality is an important aspect of agricultural production because it directly influences customer preference, market value, and overall sustainability. Micronutrients are for plant nutrition they affect the growth, development, horticultural crops. This review provides in-depth understanding role micronutrients in productivity. study investigated characteristics micronutrients, their functions growth most prevalent micronutrient deficits discusses obstacles issues associated with each treatment technique, including soil, foliar, fertigation application. It also emphasizes effects on quality, such as increased yield, improvements fruit attributes (size, color, flavor), nutritional value bioactive compounds, reduced postharvest losses, extended shelf life. Micronutrient plants have been studied, absorption, transport, accumulation, well interactions other nutrients signaling pathways. Recent research breakthroughs, studies specific synergies, innovative methods application formulation, developing technologies assessment, covered this review. The practical consequences recommendations management systems were investigated, concerns regarding sustainable efficient utilization future goals. Overall, underlines importance increasing productivity, potential influence subject.

Metal Transport Systems in Plants

Annual Review of Plant Biology, Год журнала: 2024, Номер 75(1), С. 1 - 25

Опубликована: Фев. 22, 2024

Plants take up metals, including essential micronutrients [iron (Fe), copper (Cu), zinc (Zn), and manganese (Mn)] the toxic heavy metal cadmium (Cd), from soil accumulate these metals in their edible parts, which are direct indirect intake sources for humans. Multiple transporters belonging to different families required transport a organs tissues, but only few of them have been fully functionally characterized. The systems (the uptake, translocation, distribution, redistribution, regulation) differ with plant species, depending on physiological roles, requirements each metal, anatomies tissues. To maintain homeostasis response spatiotemporal fluctuations soil, plants developed sophisticated tightly regulated mechanisms through regulation at transcriptional and/or posttranscriptional levels. manipulation some has succeeded generating crops rich low Cd accumulation. A better understanding will contribute safer crop production.

Physiological and molecular mechanisms of heavy metal accumulation in nonmycorrhizal versus mycorrhizal plants

Plant Cell & Environment, Год журнала: 2018, Номер 42(4), С. 1087 - 1103

Опубликована: Окт. 30, 2018

Abstract Uptake, translocation, detoxification, and sequestration of heavy metals (HMs) are key processes in plants to deal with excess amounts HM. Under natural conditions, plant roots often establish ecto‐ and/or arbuscular‐mycorrhizae their fungal partners, thereby altering HM accumulation host plants. This review considers the progress understanding physiological molecular mechanisms involved nonmycorrhizal versus mycorrhizal In plants, ions cells can be detoxified aid several chelators. Furthermore, HMs sequestered cell walls, vacuoles, Golgi apparatus The uptake translocation mediated by members ZIPs, NRAMPs, HMAs, detoxification mainly modulated ABCs MTPs Mycorrhizal‐induced changes due partners improvements nutritional antioxidative status fungi trigger differential expression genes both partners. Understanding that underlie is crucial for utilization remediate HM‐contaminated soils.

A high activity zinc transporter OsZIP9 mediates zinc uptake in rice

The Plant Journal, Год журнала: 2020, Номер 103(5), С. 1695 - 1709

Опубликована: Май 25, 2020

SUMMARY Zinc (Zn) is an essential micronutrient for most organisms including humans, and Zn deficiency widespread in human populations, particularly underdeveloped regions. Cereals such as rice ( Oryza sativa ) are the major dietary source of people. However, molecular mechanism underlying uptake still not fully understood. Here, we report that a member ZIP (ZRT, IRT‐like protein) family, OsZIP9, contributes to rice. It was expressed epidermal exodermal cells lateral roots, localized plasma membrane induced during deficiency. Yeast‐expressed OsZIP9 showed much higher influx transport activity than other proteins wide range concentrations. knockout plants significant reduction growth at low concentrations, but could be rescued by high supply. Compared with wild type, accumulation root, shoot grain lower lines, supply under both hydroponic paddy soil conditions. also Co activity. Natural variation expression level highly associated content milled among varieties germplasm collection. Taken together, these results show important transporter responsible take up from external media into root cells.
