plant-sensing
Plant sensing refers to the mechanisms by which plants detect and respond to environmental signals such as light, touch, gravity, temperature, and chemical cues. Understanding these sensory pathways is fundamental to plant science because they govern critical processes including growth orientation, stress responses, and adaptation to changing conditions. Research into plant sensing reveals how organisms without nervous systems can integrate complex environmental information to optimize survival and reproduction.

Scientists reviewed new sensor technologies that can continuously track how stressed plants are for water, rather than taking occasional manual measurements. These tools could transform how researchers and growers understand and respond to plant drought stress in real time.
Continuous sensors capture rapid fluctuations in plant water stress that traditional pressure-chamber measurements completely miss because those are taken only at discrete time points.
Three main approaches were evaluated: direct in-plant sensors, indirect sensors based on plant water content, and remote-sensing proxies — each with different trade-offs in accuracy, practicality, and environmental sensitivity.
Wider adoption requires better standardization across methods, since inconsistent practices currently limit the ability to compare results between studies and ecosystems.
