Key Elements for Plant Nutrition

Key Elements for Plant Nutrition

Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Microbial Leaching

Microbial Leaching

Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Microbe-Plant Interactions

Microbe-Plant Interactions

Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...

Transgenic Plants

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Area of Science:

Plant Biology
Environmental Science
Biochemistry

Background:

Selenium (Se) is a vital trace element for organisms, yet poses toxicity risks at high concentrations.
Global Se deficiency and toxicity present significant health and environmental challenges.
Plants' ability to accumulate and volatilize Se offers potential for dietary supplementation and phytoremediation.

Purpose of the Study:

To review plant mechanisms of selenium metabolism across different accumulation capacities.
To summarize genetic engineering strategies for enhancing plant Se accumulation, volatilization, and tolerance.
To evaluate the ecological implications of Se-accumulating plants in environmental management.

Main Methods:

Literature review of plant Se metabolism and genetic engineering studies.
Analysis of plant Se accumulation categories: non-accumulators, accumulators, and hyperaccumulators.
Synthesis of findings on Se's impact on plant-associated ecological interactions.

Main Results:

Plant Se accumulation varies significantly, with distinct metabolic pathways.
Genetic engineering has successfully enhanced plant Se traits, demonstrated in field trials.
Plant Se accumulation alters ecological interactions, providing defense against pathogens and herbivores but supporting specialist organisms.

Conclusions:

Understanding plant Se metabolism is crucial for harnessing its benefits.
Ecological impacts of Se-accumulating plants must be assessed for safe and effective phytoremediation.
Se-accumulating plants offer a dual role in Se management: dietary source and environmental remediation tool.
