Photoisomerization-engineered fluorescent probe for innovative detection and bioimaging of salicylic acid during salt stress in plants

Key Points

• Salicylic acid levels were effectively monitored using a photoisomerization-engineered fluorescent probe, enabling real-time bioimaging.
• The probe showed a significant increase in sensitivity towards salicylic acid, allowing detection under varying salt stress conditions.
• Assessment involved applying the fluorescent probe in plant models subjected to controlled salt stress experiments.
• Implications include enhancing our understanding of plant responses to stress and guiding future agricultural practices.
