biostudies-literatureUnknown2Shiojiri KPlants are known to mount a defensive response when exposed to volatile chemicals from other plants, but the critical concentration required for this response is not known. We showed that intermittent exposure over a period of 3 weeks to trace amounts (less than 140 pptV) of green leaf volatiles emitted by a freshly damaged Arabidopsis plant induced physiological (defensive) responses in undamaged neighbouring plants. These results demonstrated that plants can respond to long-term repeated exposures to subcritical amounts of chemical signals.Scientific reports378https://www.ebi.ac.uk/biostudies/studies/S-EPMC3334854biostudies-literatureIntermittent exposure to traces of green leaf volatiles triggers a plant response.PMC3334854Shiojiri KMatsui KOzawa RSabelis MWTakabayashi JfalseIntermittent exposure to traces of green leaf volatiles triggers a plant response.Plants are known to mount a defensive response when exposed to volatile chemicals from other plants, but the critical concentration required for this response is not known.
