We found that plants emit sounds, and that stressed plants—both drought-stressed (Dry) and cut plants (Cut; see STAR Methods)—emit significantly more sounds than plants of any of the control groups (p < e−6, Wilcoxon test for each of the 12 comparisons with Holm-Bonferroni correction). Three controls were used for each plant species and treatment: recording from the same plant before treatment (Self-control), recording from an untreated same-species neighbor plant (Neighbor-control), and recording a pot wit
