20.500.12556/DiRROS-20096 Intertwined roles of reactive oxygen species and salicylic acid signaling are crucial for the plant response to biotic stress One of the earliest hallmarks of plant immune response is production of reactive oxygen species (ROS) in different subcellular compartments, which regulate plant immunity. A suitable equilibrium, which is crucial to prevent ROS overaccumulation leading to oxidative stress, is maintained by salicylic acid (SA), a chief regulator of ROS. However, ROS not only act downstream of SA signaling, but are also proposed to be a central component of a self-amplifying loop that regulates SA signaling as well as the interaction balance between different phytohormones. The exact role of this crosstalk, the position where SA interferes with ROS signaling and ROS interferes with SA signaling and the outcome of this regulation, depend on the origin of ROS but also on the pathosystem. The precise spatiotemporal regulation of organelle-specific ROS and SA levels determine the effectiveness of pathogen arrest and is therefore crucial for a successful immune response. However, the regulatory interplay behind still remains poorly understood, as up until now, the role of organelle-specific ROS and SA in hypersensitive response (HR)-conferred resistance has mostly been studied by altering the level of a single component. In order to address these aspects, a sophisticated combination of research methods for monitoring the spatiotemporal dynamics of key players and transcriptional activity in plants is needed and will most probably consist of biosensors and precision transcriptomics. plant immune response reactive oxygen species ROS salicylic acid programmed cell death biotic stress biotechnology rastlinski imunski odgovor reaktivne kisikove spojine salicilna kislina programirana celična smrt biotski stres biotehnologija true false true Angleški jezik Slovenski jezik Neznano 2024-08-05 14:13:22 2024-08-05 14:13:22 2024-08-07 03:42:25 0000-00-00 00:00:00 2022 0 0 Nasl. z nasl. zaslona; Opis vira z dne 19. 5. 2022; str.
