Study found #injured #plants #emit certain #chemicalcompounds which can infiltrate a healthy plant’s inner tissues and activate #defenses from within its cells. A better understanding of this mechanism could allow #scientists and #farmers to help fortify plants against #insect attacks or #drought long before they happen. study marks 1st x researchers have been able to visualize plant-to-plant communication https://www.nature.com/articles/s41467-023-41589-9 #ClimateCrisis #farming #agriculture
