Photoprotective function of energy dissipation by thermal processes and photorespiratory mechanisms in Jatropha curcas plants during different intensities of drought and after recovery.
Abstract The role of photorespiration in plants under drought is not well understood. It can act both as an alternative electron sink and a source of reactive oxygen species (ROS). In this study, weExpand
