Researchers have long known that the plant hormone auxin, or indole-3-acetic acid, regulates a broad range of biological functions, including flowering, fruit ripening, and root elongation. But they didn’t realize the sophistication and complexity with which plants coordinate the levels and location of this potent hormone in cells, says Jürgen Kleine-Vehn, a plant biologist at the University of Natural Resources & Life Sciences, in Vienna.

Kleine-Vehn and his colleagues have discovered a . . .
