Arsenite antiporters ACR3/3;1 are critical for Se-enhanced plant growth and As accumulation in As-hyperaccumulators Pteris multifida and Pteris cretica.

Summary: Did you know some plants can actually eat toxic pollution? Scientists are studying special ferns that naturally suck up arsenic, a dangerous poison found in some soils. They discovered that giving these ferns a little bit of selenium—a natural mineral—makes them grow bigger and soak up even more of the poison! The ferns use tiny internal "pumps" to safely store the toxic arsenic. This amazing discovery could help us use plants to clean up polluted land and make our environment safer.
