Too Much, Take it Back: PAP Moves from the Cytosol to Plastids and Mitochondria for Degradation via PAPST2
Plants need to strike a fine balance between the production, transport, and degradation of stress signals in order to optimize growth in fluctuating environmental conditions. The signal 3’phosphoadenosine 5’phosphate (PAP) accumulates during drought and light stress and induces stress-responsive gene expression (Estavillo et al., 2011). Sulfur transfer from 3’phosphoadenosine 5’phosphosulfate (PAPS) to acceptor compounds in […]
