Detection of abundant sulphate-reducing bacteria in marine oxic sediment layers by a combined cultivation and molecular approach.

abstract：:Reactive oxygen species (ROS) play an important role during host-pathogen interactions and are often an indication of induced host defence responses. In this study, we demonstrate for the first time that Puccinia triticina (Pt) generates ROS, including superoxide, H2 O2 and hydroxyl radicals, during wheat infection. T...
