However, we do not know whether different biotic stresses share a common response or which signaling pathways are involved in responses to different biotic stresses. We investigated the common and specific responses of Arabidopsis thaliana to three biotic stress agents: Spodoptera littoralis, Myzus persicae, and the pathogen Pseudomonas syringae.<h4>Methodology/principal findings</h4>We used electrophysiology to determine the plasma membrane potential (V(m)) and we performed a gene microarray transcriptome analysis on Arabidopsis upon either herbivory or bacterial infection. V(m) depolarization was induced by insect attack; however, the response was mPloS onee46673https://www.ebi.ac.uk/biostudies/studies/S-EPMC3484130biostudies-literatureDynamics of membrane potential variation and gene expression induced by Spodoptera littoralis, Myzus persicae, and Pseudomonas syringae in Arabidopsis.PMC3484130Maffei MEPaponov IABertea CMOcchipinti ABricchi IfalseDynamics of membrane potential variation and gene expression induced by Spodoptera littoralis, Myzus persicae, and Pseudomonas syringae in Arabidopsis.<h4>Background</h4>Biotic stress induced by various herbivores and pathogens invokes plant responses involving different defense mechanisms.
