Plant root border cells actively exchange glucose with their environment. These cells demonstrate both glucose uptake and release, with net exchange influenced by soil conditions.

Area of Science:

  • Plant biology
  • Root physiology
  • Rhizosphere interactions

Background:

  • Border cells are released from plant root tips and remain viable in the rhizosphere for up to a week.
  • Their role in nutrient exchange within the rhizosphere is not fully understood.

Purpose of the Study:

  • To investigate the controlled glucose exchange capabilities of plant root border cells.
  • To determine if border cells actively transport or passively diffuse glucose.

Main Methods:

  • Border cells from Zea mays L. root tips were incubated with (14)C-labelled D-glucose.
  • Hexose transport inhibitor phlorizin was used to differentiate between active uptake and diffusion.
  • Glucose uptake and efflux over time were monitored under varying glucose concentrations.

Main Results:

  • Glucose uptake by border cells increased with glucose concentration (0.2–20 mm).
  • At low glucose concentrations (0.2 mm), uptake was primarily active, inhibited by phlorizin.
  • At higher concentrations (2 and 20 mm), uptake was mainly by diffusion, with negligible phlorizin inhibition.
  • Live border cells showed time-dependent glucose efflux, unlike heat-killed cells.

Conclusions:

  • Plant root border cells are capable of active glucose uptake and release.
  • Under experimental conditions, glucose uptake and efflux were of comparable magnitude.
  • Net glucose exchange in the rhizosphere is likely dependent on local soil environmental factors.
