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...

Inorganic Nitrogen Assimilation

Inorganic Nitrogen Assimilation

Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme nitrate reductase...

Water and Mineral Acquisition

Water and Mineral Acquisition

Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

Absorption of Nutrients

Absorption of Nutrients

Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream.
Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

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.

Global Change Biology

Background:

Nutrient resorption is crucial for plants, influencing nutrient cycling and ecosystem functions.
Foliar nutrient resorption patterns can indicate plant nutrient limitation.
Stoichiometric approaches offer insights into nutrient dynamics.

Purpose of the Study:

To assess foliar nutrient resorption patterns using a stoichiometric approach.
To explore relationships between nitrogen : phosphorus (N : P) resorption ratios and nutrient limitation.
To investigate the link between N : P resorption ratios and soil nutrient availability across various scales.

Main Methods:

Utilized a stoichiometric approach to analyze foliar resorption.
Examined N : P resorption ratios at global, regional, and local scales.
Correlated N : P resorption ratios with environmental factors like latitude, temperature, precipitation, and soil properties.

Main Results:

Significant global variation in N : P resorption ratios was observed.
N : P resorption ratios increased with latitude and decreased with temperature and precipitation.
Tropical sites and highly weathered soils exhibited the lowest N : P resorption ratios.
Resorption ratios varied with forest age and among species.

Conclusions:

Foliar N : P resorption stoichiometry provides valuable insights into nutrient cycling and limitation.
Stoichiometric flexibility in resorption may regulate terrestrial ecosystem responses to global change.
Further research is needed to understand the role of resorption in global change.
