Molecular mechanism of plant response to copper stress: A review
2024年2月1日 · Copper is absorbed from the soil by plants in a manner similar to iron uptake by dicotyledonous and non-gramineous monocotyledonous plants. Copper ions can bind to cell walls and the outer membrane surface of plant root cells, where Cu 2+ is reduced to Cu + by Fe reductase oxidase (FRO4/FRO5), and the reduced Cu + is transported across the ...
Physiological and Molecular Mechanisms of Plant Responses to Copper …
The transport process of Cu ions is primarily divided into the following four steps: (1) absorption by the roots; (2) isolation in the vacuoles; (3) loading in the xylem and phloem; and (4) distribution and redistribution of the nodes [33,34]. Different transporters are required for these processes.
Copper bioavailability, uptake, toxicity and tolerance in plants: A ...
2021年1月1日 · The absorption of Cu in plants can generate hydroxyl radical (OH.) through Fenton and Haber-Weiss reactions. The radical can also bind to the plasma membrane non-selective cationic channel (NSCC) which opens the channels for Ca 2+ leading to enhanced root growth (Rodrigo-Moreno et al., 2013).
Advances in understanding of copper function and transport in plants ...
2022年1月1日 · The proposed model of the role of copper in plant development and reproduction. Copper deficiency causes pleiotropic effects on plant growth and development that ultimately reduce seed set and quality. The increased shoot branching, flower bud growth, and aberrant stigma morphology are likely associated with altered auxin signaling.
Molecular Mechanisms of Plant Responses to Copper: From
2024年6月26日 · These coordination groups can undergo various physical or chemical reactions with positively charged Cu ions, adsorb excess Cu ions on the cell wall, and inhibit the entry of Cu ions into protoplasts. This process reduces the toxic effects of …
The Copper Transport Mechanism in Plants | SpringerLink
2022年10月30日 · Puig reviewed and stated that COPT1 plays role in absorption of Cu in plant roots, COPT6 plays role in the distribution of Cu in plant shoots, and COPT5 activates and organizes Cu from organelles meant for storage. Therefore, in the light of aforementioned functions of COPT proteins, it can be stated that the COPT proteins play an indispensable ...
Copper in plants: Acquisition, transport and interactions
2009年5月1日 · Accordingly, excess copper is present in certain regions and environments, and exposure to that can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen...
Physiological and Molecular Mechanisms of Plant Responses to Copper …
2022年10月26日 · This review summarizes the biological functions of Cu, the toxicity of excess Cu to plant growth and development, the roles of Cu transport proteins and chaperone proteins, and the transport process of Cu in plants, as well as the mechanisms of detoxification and tolerance of Cu in plants.
Copper: uptake, toxicity and tolerance in plants and management …
2021年4月28日 · Overview of copper uptake, and roles (essential and harmful) in plants. Copper is absorbed in plants by Cu trafficking proteins viz COPT/Cry family proteins (COPT1, COPT2, COPT3 etc.) as well as via Ptype ATPas and ZIP proteins.
