A near-infrared ratiometric fluorescent probe for visual sensing of H2S and monitoring its fluctuation in plant roots under drought and flooding stresses

Key Points

• H2S levels fluctuate significantly in plant roots under drought and flooding conditions, indicating adaptive responses to stress.
• Changes in H2S were monitored using a near-infrared ratiometric fluorescent probe optimized for plant applications.
• Experimental setup included observing plant roots under controlled drought and flooding stress scenarios over several days.
• Understanding the role of H2S in plant stress response may enable improved agricultural practices for water management.
