Mammals and plants share trace element absorption mechanisms, utilizing constitutive and inducible systems for nutrient uptake. Monocotyledonous plants uniquely employ phytosiderophores for iron uptake, crucial for nutrient acquisition from insoluble sources.

Area of Science:

  • Plant and animal physiology
  • Biochemistry
  • Environmental science

Background:

  • Trace element absorption and transport show parallels between mammals and plants.
  • Uptake mechanisms involve adsorption thermodynamics, charged surfaces, ligands, and redox systems, particularly for iron.
  • Nutrient acquisition relies on constitutive systems and inducible 'turbo' systems for deficiency conditions.

Purpose of the Study:

  • To elucidate the similarities and differences in trace element absorption and transport between mammals and plants.
  • To detail the specific mechanisms of iron uptake in dicotyledonous and monocotyledonous plants.
  • To explore the role of phytosiderophores in iron acquisition by graminaceous plants.

Main Methods:

  • Thermodynamic analysis of adsorption on charged surfaces.

  • Investigation of constitutive and inducible nutrient uptake systems.
  • Comparative study of iron uptake pathways in dicots and monocots, including phytosiderophore systems.

    • Main Results:

    • Identified shared principles in trace element chemistry for uptake in both mammals and plants.
    • Differentiated iron uptake systems: dicots use an upregulated constitutive system, while monocots utilize a distinct inducible phytosiderophore system.
    • Highlighted the significance of phytosiderophores for iron entry into plants from insoluble sources.

    Conclusions:

    • Trace element homeostasis is maintained through conserved biochemical principles across kingdoms.
    • Phytosiderophore-mediated iron uptake is a critical adaptation for graminaceous plants in iron-limited environments.
    • Understanding these mechanisms is vital for plant nutrition and agriculture.
