Plants keep each other informed of danger. When insects attack your garden, plants don't simply endure the assault in silence. Research reveals plants broadcast molecular distress signals to warn their neighbors about incoming threats. Plants have chemical communication networks Scientists at Purdue University have decoded how plants communicate via volatile organic compounds (VOCs). These invisible airborne molecules function as an emergency alert system between plants. Professor Natalia Dudareva's team in Purdue's departments of Biochemistry and Horticulture spent years investigating this chemical language. Their findings show that...
