• Scientists have known for some time that plants can eavesdrop on damage to other plants nearby. Doing so can benefit a plant, which can take steps to defend itself. Scientists are considering harnessing this process to fight agricultural pests without having to use pesticides.
  • The new study, published in Nature Communications on October 17, could help unlock long-standing questions in the field of plant defence and pave the way to protect crops without pesticides.
  • In the final analysis, Dr. Gilroy was optimistic about the sort of questions we could pursue now that we can watch calcium signals in plants. Plants lack brains but obtain information about the world and use it in meaningful ways just like we do.
