AI Technical Summary
Current technologies cannot quickly and accurately determine crops' ability to absorb cadmium, arsenic, and selenium without damage, which threatens the quality of agricultural products and human nutritional health.
By inoculating the rhizosphere environment of crops with Pseudomonas monteilii SSMGP 4-3, and combining microelectrode arrays and electrochemical impedance spectroscopy sensors, the electrophysiological signals of plant roots and the electrochemical responses of microorganisms were recorded in real time, and a rapid determination method was established using machine learning models.
It enables rapid, non-destructive, and accurate determination of the absorption capacity of crops for cadmium, arsenic, and selenium, and is suitable for early screening in breeding and field monitoring, improving the sensitivity and accuracy of detection.
