Microbes and Other Elemental Cycles01:24

Microbes and Other Elemental Cycles

76
Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...

The Phosphorus Cycle01:21

The Phosphorus Cycle

45.1K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

Light Acquisition02:16

Light Acquisition

9.9K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

1.3K
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Key Elements for Plant Nutrition02:35

Key Elements for Plant Nutrition

25.1K
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...

Sulfur Assimilation01:20

Sulfur Assimilation

537
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...

Area of Science:

  • Plant physiology
  • Soil science
  • Nutrient cycling

Background:

  • Plants using carboxylate release for phosphorus (P) mobilization often show high leaf manganese ([Mn]).
  • Carboxylates mobilize soil P and micronutrients, notably Mn, even in low-availability soils.
  • This suggests a link between P acquisition strategy and Mn accumulation.

Purpose of the Study:

  • To propose leaf [Mn] as a selection criterion for genotypes efficient in low-P conditions.
  • To explore leaf [Mn] for screening belowground traits related to nutrient acquisition in low-P environments.

Main Methods:

  • Observational analysis of plant leaf nutrient concentrations.
  • Correlation studies between P-mobilizing strategies and micronutrient accumulation.
  • Comparative analysis across species in varying soil P availability.

Main Results:

  • Plants employing carboxylate-based P mobilization exhibit significantly elevated leaf [Mn].
  • Mn accumulation is pronounced even when soil Mn availability is low.
  • Leaf [Mn] serves as a reliable indicator of P acquisition efficiency.

Conclusions:

  • Leaf [Mn] concentration is a valuable indicator for selecting plants with enhanced P acquisition capabilities in low-P soils.
  • This metric can be utilized to screen for specific belowground functional traits related to nutrient acquisition strategies.
