A shape-shifting plant receptor expands the landscape of small-molecule sensing
Plant Science Research WeeklyDesigning small-molecule biosensors that are both sensitive and versatile remains a central challenge in synthetic biology, yet such tools are indispensable for environmental monitoring, cellular control, and emerging biotechnologies. In this study, Tian and colleagues exploit an unexpected feature of…
Illuminating plant immunity: A live sensor to watch salicylic acid in action
Plant Science Research WeeklySalicylic acid (SA) is best known as a central hormone orchestrating plant immune response, including the hypersensitive reaction and systemic acquired resistance. Beyond defense, SA also influences plant growth and development, highlighting a delicate role in balancing the trade-off between immunity…
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.
