  "main_findings": "After 24 h exposure to RF-EMF (1.8–7.8 V/m) generated by AM 1.287 MHz transmitting antennas, etiolated duckweed showed alanine accumulation in cells, described as a universal stress signal. The effect magnitude qualitatively corresponded to exposure level, and 10 mM vitamin C completely suppressed alanine accumulation.",
