Spatial organization of ROS signaling at the plasma membrane
Plant Science Research WeeklyGenetic studies in Arabidopsis have identified a lot of the participants in signal transduction pathways, but often its less clear precisely where they function. As an example, although it is well known that H2O2 (hydrogen peroxide) production by RBOHs in the apoplast triggers many downstream cellular…
Hydrogen peroxide: A new messenger in the phosphate starvation response
Plant Science Research WeeklyPhosphorus (P) is one of the indispensable macronutrients that fuel plant growth and development. However, most soil P is locked in insoluble complexes with heavy metals, making it largely inaccessible to plants. In rice, the MYB transcription factor PHOSPHATE STARVATION RESPONSE 2 (OsPHR2) acts as a…
