Optical Sensing Technologies to Elucidate the Interplay between Plant and Microbes

Area of Science:

• Plant biology
• Microbiology
• Biosensing technologies

Background:

• Plant-microbe interactions are fundamental to ecosystem function and soil health.
• Effective communication between plants and rhizosphere microbes is key to understanding these interactions.
• Current methods often lack suitability for field applications.

Purpose of the Study:

• To review plant-microbe interactions and their impact on plants.
• To summarize optical biosensing technologies for plant-microbe interaction studies.
• To highlight the need for novel biosensors for in-situ measurements.

Main Methods:

• Review of existing literature on plant-microbe interactions.
• Summary of optical and electrochemical biosensing technologies.
• Focus on biosensors for root exudates and phytohormones.

Main Results:

• Plants and microbes engage in complex interactions influencing each other.
• Optical biosensors can elucidate plant-microbe communication and detect pathogens.
• Existing biosensors are often not field-deployable, costly, and difficult to develop.

Conclusions:

• Advanced optical biosensing technologies are crucial for studying plant-microbe dynamics.
• There is a significant need for low-cost, in-situ biosensors for plant science research.
• Development of such biosensors will improve the understanding of plant responses to stress.
