Summary
Selenium (Se) influences plant micronutrient levels, affecting essential elements like iron and zinc. Understanding these bidirectional effects is key for managing plant nutrient balance and mitigating toxicity.
Area of Science:
- Plant Science
- Environmental Science
- Biochemistry
Background:
- Microelement nutrient imbalance poses significant environmental challenges, impacting ecosystems.
- While microelements are vital for plant life cycles, their precise control remains difficult due to narrow safe concentration ranges.
- Selenium (Se) is essential for animals and humans, and emerging research highlights its importance in plant micronutrient interactions.
Approach:
- This review systematically analyzes the bidirectional effects of selenium on various plant micronutrients, including iron, zinc, copper, manganese, nickel, molybdenum, sodium, chlorine, and boron.
- The underlying regulatory mechanisms by which selenium influences these micronutrients are examined.
- The role of selenium in alleviating elemental toxicity and adjusting micronutrient concentrations in plants is further explored.
Key Points:
- Selenium modulates plant uptake, accumulation, and detoxification of essential microelements.
- Selenium's influence extends to soil properties, microbial activity, and plant physiological processes like metal chelation and antioxidant defense.
- The review details how selenium impacts gene expression related to element transport and tolerance.
Conclusions:
- Selenium plays a critical, multifaceted role in regulating plant micronutrient homeostasis.
- Understanding selenium-micronutrient interactions is crucial for developing strategies to manage plant nutrition and environmental stress.
- Further research is needed to fully elucidate these complex interactions and their applications.

Key Elements for Plant Nutrition
20.6K
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...

The Roles of Bacteria and Fungi in Plant Nutrition
39.6K
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.

Sulfur Assimilation
66
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...

Overview of Metabolism
31.8K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Vitamins
931
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...
