Cover Story: Phytopathogens causes worldwide significant crop losses. However, their exploitation for crop welfare is relatively unknown. Here, we show that the microbial volatile organic compound (mVOC) profile of the bacterial phytopathogen Erwinia amylovora enhances Arabidopsis thaliana shoot and root growth. E. amylovora mVOCs (including 1-nonanol and 1-dodecanol) triggered early signaling events, including plasma transmembrane potential Vm depolarization, cytosolic Ca2+ fluctuation, K+-gated channel activity, and reactive oxygen species (ROS) and nitric oxide (NO) burst from a few minutes to 16 h upon exposure. Our results show that E. amylovora mVOCs affect A. thaliana growth through a cascade of early events and gene regulation that involve phytohormones, ROS and NO. View this paper

  • Nicole Schupp

Nuclear factor erythroid 2-related factor 2 (Nrf2) is downregulated in chronic kidney disease (CKD). Activation of Nrf2 might be a therapeutic option in CKD. Here we investigate the effect of Nrf2 activation on aldosterone (Aldo)-induced renal injury...
