Apoplastic pH acts as a chemical switch in plants by modulating H2O2 redox potential
Plant Science Research WeeklyEnvironmental stimuli, such as drought and salinity, alter cellular conditions including apoplastic pH (pHApo) in plants. These stimuli often lead to an elevation in pHApo which is closely associated with cell functions and plant growth. However, the mechanism behind is largely unexplored. A recent study…
A biosensor for ER redox dynamics highlights ER oxidoreductins
The Plant Cell: In a NutshellUgalde et al. report that dynamic monitoring of the ER luminal glutathione redox potential highlights the role of ER oxidoreductins in defining redox conditions and the interplay between different redox inputs during hypoxia and reductive stress.
