Overview of DSP-type MAPK phosphatases for multiple abiotic signaling pathways and putative regulatory mechanisms. MAPK phosphatases participate in responses to UV light, wounding, osmotic stress, salt stress and reactive oxygen species (ROS) stress. The different pathways and putative regulatory mechanisms are described in text. Dash lines represent the indirect regulation indicated from genetic data; and solid lines represent the direct regulation indicated from physical interactions.
