abstract

  • Background/Question/Methods Plants are able to perceive and plastically respond to a myriad of biotic and abiotic challenges. Of particular interest are plant's responses to probable future damages by'eavesdropping'on their damaged neighbors. Here we tested the hypothesis that plants are able to perceive cues of anticipated drought by eavesdropping on their droughted neighbors. A series of Pisum sativum split-root plants were grown so each one of their roots shared its rooting volume with one root of a different neighbor. Results/Conclusions Target plants rapidly closed their stomata following an osmotic stress induction to their neighbor. No such communication took place when the roots of the target plants did not share their rooting volume with their stressed neighbor, implying that the stress cues were transmitted among the roots rather than the shoots. Furthermore, target …
