Humans and Plants Are Alike: Males Don't Listen to Females, Scientists Say

Studies conducted by UC Irvine show that male plants don't listen to female plants, even when their survival depends on it.

    Male Plants Don't Listen to Female Plants

    Humans and plants are all alike: males don't listen to females, even when their lives depend on it, scientists say. (Published Friday, Feb. 22, 2019)

    You call him stubborn; he claims it was just a miscommunication. 

    Turns out the conversations happening in your house are also happening in the greenhouse. 

    "There's obvious parallels you can draw from stereotypes about humans, and relative listening abilities of males and females," said Dr. Kailen Mooney, professor at the University of California, Irvine School of Biological Sciences. "But in the case of plants, it actually makes sense to us from an evolutionary perspective."

    Mooney's lab has spent eight years studying mule fat plants, which are part of the sunflower and daisy family, and native to Southern California.

    "What we're interested in was whether or not males and females speak and listen to each other when they are being eaten by insects," Mooney said.

    The plants communicate to each other through chemicals and smells that they produce as part of their immune system.

    "What we found is that females are good listeners," Mooney said. "But males only listen to the volatiles (the smells) emitted by other males. And so, they ignore females."

    Mule fat plants are scientifically known as Baccharis Salicfolia. The discovery about their communication offers insights useful for agriculture production to use fewer insecticides when managing crops.

    But let's be honest, the scientists are just confirming something most of our mothers have said for years. Insert eye roll and dramatic sigh.
