Summary
This summary is machine-generated.

Rice plants reallocate zinc internally, with the stem to reproductive tissue being the main barrier to grain zinc density. Enhancing root uptake alone won't significantly boost grain zinc levels.

Area of Science:

  • Agronomy
  • Plant Physiology
  • Nutrient Management

Background:

  • Enhancing cereal grain zinc density is a key goal in agronomy and breeding.
  • Understanding internal zinc (Zn) allocation and reallocation is crucial for improving crop nutrition.
  • Developing conceptual models of whole-plant Zn dynamics aids in optimizing crop management and breeding strategies.

Purpose of the Study:

  • To investigate the internal allocation and reallocation of zinc in rice plants.
  • To develop a conceptual model of whole-plant zinc dynamics.
  • To identify barriers to zinc transport to rice grains.

Main Methods:

  • Utilized (70)Zn isotope tracing in solution culture experiments at different crop developmental stages.
  • Analyzed within-grain zinc distribution.
  • Re-analyzed and re-interpreted data from two previously published experiments.

Main Results:

  • Plant zinc accumulation during grain filling exceeded direct zinc allocation to grains.
  • Zinc absorbed during grain filling was allocated to both grains and leaves, with leaf-allocated zinc replacing previously stored zinc.
  • A major barrier to zinc transport was identified between rice stems and reproductive tissues.
  • Rice plants maintained leaf and reproductive tissue zinc concentrations around 20 mg Zn kg(-1) dry matter under low supply, prioritizing these tissues over stems, sheaths, and roots.

Conclusions:

  • The primary limitation for increasing grain zinc density in rice is the transport step from stem to reproductive tissues.
  • Improving root-to-shoot zinc transfer alone is unlikely to proportionally increase grain zinc concentration.
