  • Photoperiod stress, a novel abiotic stress in plants (project led by Anne Cortleven)
    Several years ago, we have discovered that Arabidopsis plants respond to an extension of daylength by a strong stress response during the following night. Hallmarks of the photoperiod stress syndrome are an increased concentration of stress hormones and of reactive oxygen species (ROS). The stress response genes that are activated by photoperiod stress resemble those of the response to pathogens. Intriguingly, photoperiod stress treatment increases resistance to pathogens. It is thought that photoperiod stress is caused by malfunctioning of the circadian clock. Root-derived cytokinin alleviates and auxin increases photoperiod stress symptoms. This project is led independently by Anne Cortleven.
