Establishing methods for rapid and early detection of pathogen-infected crops is crucial to improve plant disease management and reduce crop loss.
Typically, plant disease diagnosis involves a simple visual inspection of plants for illness signs and intensity. It is more reliable than existing strategies as it enables accurate recognition and early detection of bacterial infection, both of which are crucial to conserving crop plants that would otherwise be ruined,” describes Gajendra Pratap Singh, scientific director and principal private investigator at DiSTAP and co-lead author.
“The outcomes revealed that the Raman spectroscopy-based method can swiftly detect and quantify natural immunity reaction in plants contaminated with bacterial pathogens. Scientists from MIT, TTL, Nanyang Technological University, and National University of Singapore are collaboratively establishing new tools for the continuous measurement of crucial plant metabolites and hormonal agents for novel discovery, deeper understanding and control of plant biosynthetic pathways in ways not yet possible, especially in the context of green leafy vegetables; leveraging these brand-new strategies to engineer plants with extremely desirable properties for global food security, including high-yield density production, and dry spell and pathogen resistance; and applying these technologies to improve city farming.
Due to the increasing demand for worldwide food supply and security, there is a growing need to improve farming production systems and increase crop productivity. Globally, bacterial pathogen infection in crop plants is one of the major factors to agricultural yield losses. Climate modification also contributes to the problem by accelerating the spread of plant illness. Developing methods for fast and early detection of pathogen-infected crops is essential to enhance plant disease management and lower crop loss.
The advancement by SMART and TLL researchers uses a faster and more accurate method to identify bacterial infection in crop plants at an earlier stage, as compared to existing methods. The new outcomes appear in a paper titled “Rapid detection and metrology of plant inherent resistance reaction using Raman spectroscopy” published in the journal Frontiers in Plant Science.

” The early detection of pathogen-infected crop plants is a significant action to enhance plant illness management,” says Chua Nam Hai, DiSTAP co-lead principal investigator, professor, TLL deputy chair, and co-corresponding author. “It will permit the selective and fast elimination of pathogen load and curb the additional spread of disease to other neighboring crops.”
Typically, plant disease medical diagnosis involves a basic visual assessment of plants for disease signs and seriousness. “Visual examination methods are often inadequate, as disease symptoms generally manifest only at reasonably later phases of infection, when the pathogen load is reparative and already high steps are restricted. New techniques are needed for quick and early detection of bacterial infection. The idea would be similar to having medical tests to identify human illness at an early stage, rather of waiting on visual symptoms to reveal, so that early intervention or treatment can be used,” says MIT Professor Rajeev Ram, who is a DiSTAP principal investigator and co-corresponding author on the paper.
While existing methods, such as existing molecular detection approaches, can detect bacterial infection in plants, they are typically restricted in their usage. Molecular detection methods mostly depend on the schedule of pathogen-specific gene series or antibodies to determine bacterial infection in crops; the implementation is nonadaptable and likewise lengthy for on-site field application due to the high expense and large devices required, making it not practical for usage in agricultural farms.
” At DiSTAP, we have established a quantitative Raman spectroscopy-based algorithm that can help farmers to determine bacterial infection rapidly. The developed diagnostic algorithm makes use of Raman spectral biomarkers and can be easily carried out in cloud-based computing and prediction platforms. It is more reliable than existing strategies as it enables accurate identification and early detection of bacterial infection, both of which are vital to conserving crop plants that would otherwise be ruined,” discusses Gajendra Pratap Singh, clinical director and primary detective at DiSTAP and co-lead author.
A portable Raman system can be utilized on farms and supplies farmers with a precise and easy yes-or-no reaction when utilized to evaluate for the presence of bacterial infections in crops. The development of this rapid and noninvasive approach could improve plant illness management and have a transformative influence on farming farms by efficiently reducing farming yield loss and increasing efficiency.
” Using the diagnostic algorithm approach, we experimented on numerous edible plants such as choy amount,” says DiSTAP and TLL principal detective and co-corresponding author Rajani Sarojam. “The outcomes revealed that the Raman spectroscopy-based approach can swiftly detect and measure innate immunity response in plants infected with bacterial pathogens. We believe that this innovation will be beneficial for farming farms to increase their productivity by reducing their yield loss due to plant illness.”
The scientists are presently dealing with the development of high-throughput, tailor-made portable or hand-held Raman spectrometers that will allow Raman spectral analysis to be rapidly and quickly performed on field-grown crops.
