Popis: The jasmonic acid (JA) signalling pathway is involved in the plant response to drought stress. JA and other hormones synergistically regulate the drought response in plants. However, the molecular mechanism underlying this synergism remains poorly defined. In this study, transcriptome analyses of guard cells and qPCR experiments revealed that MYC2 negatively regulated the negative regulator of abscisic acid (ABA) signalling, SlPP2C1, and the type-B response regulator (RR) in the cytokinin (CK) pathway, SlRR26, and this negative regulation was direct. SlRR26 overexpression reduced drought tolerance in transgenic tomatoes, while slrr26
