The Raman spectroscopy-based technique makes it possible for early detection and metrology of pathogens in plants, to improve plant illness management.
Researchers from the Disruptive and Sustainable Technologies for Agricultural Precision (DiSTAP) Interdisciplinary Research Group (IRG) of Singapore- MIT Alliance for Research and Technology (CLEVER), MIT’s research study business in Singapore, and their regional partners from Temasek Life Sciences Laboratory (TLL), have actually established a quick Raman spectroscopy-based technique for identifying and measuring early bacterial infection in crops. The Raman spectral biomarkers and diagnostic algorithm allow the noninvasive and early medical diagnosis of bacterial infections in crop plants, which can be crucial for the development of plant illness management and farming efficiency.
Due to the increasing need for international food supply and security, there is a growing requirement to enhance farming production systems and increase crop efficiency. Globally, bacterial pathogen infection in crop plants is among the significant factors to farming yield losses. Climate modification likewise contributes to the issue by speeding up the spread of plant illness. Hence, establishing techniques for quick and early detection of pathogen-infected crops is very important to enhance plant illness management and decrease crop loss.
The advancement by SMART and TLL scientists provides a much faster and more precise technique to find bacterial infection in crop plants at an earlier phase, as compared to existing strategies. The brand-new outcomes appear in a paper entitled “Rapid detection and quantification of plant innate immunity response using Raman spectroscopy” released in the journal Frontiers in Plant Science

“The early detection of pathogen-infected crop plants is a significant step to improve plant disease management,” states Chua Nam Hai, DiSTAP co-lead primary detective, teacher, TLL deputy chair, and co-corresponding author. “It will allow the fast and selective removal of pathogen load and curb the further spread of disease to other neighboring crops.”
Traditionally, plant illness medical diagnosis includes a basic visual assessment of plants for illness signs and intensity. “Visual inspection methods are often ineffective, as disease symptoms usually manifest only at relatively later stages of infection, when the pathogen load is already high and reparative measures are limited. Hence, new methods are required for rapid and early detection of bacterial infection. The idea would be akin to having medical tests to identify human diseases at an early stage, instead of waiting for visual symptoms to show, so that early intervention or treatment can be applied,” states MIT Professor Rajeev Ram, who is a DiSTAP principal detective and co-corresponding author on the paper.
While existing strategies, such as present molecular detection techniques, can find bacterial infection in plants, they are typically restricted in their usage. Molecular detection techniques mainly depend upon the accessibility of pathogen-specific gene series or antibodies to recognize bacterial infection in crops; the application is likewise lengthy and nonadaptable for on-site field application due to the high expense and large devices needed, making it not practical for usage in farming farms.
“At DiSTAP, we have developed a quantitative Raman spectroscopy-based algorithm that can help farmers to identify bacterial infection rapidly. The developed diagnostic algorithm makes use of Raman spectral biomarkers and can be easily implemented in cloud-based computing and prediction platforms. It is more effective than existing techniques as it enables accurate identification and early detection of bacterial infection, both of which are crucial to saving crop plants that would otherwise be destroyed,” describes Gajendra Pratap Singh, clinical director and primary detective at DiSTAP and co-lead author.
A portable Raman system can be utilized on farms and offers farmers with a precise and easy yes-or-no reaction when utilized to evaluate for the existence of bacterial infections in crops. The advancement of this quick and noninvasive technique might enhance plant illness management and have a transformative influence on farming farms by effectively decreasing farming yield loss and increasing efficiency.
“Using the diagnostic algorithm method, we experimented on several edible plants such as choy sum,” states DiSTAP and TLL primary detective and co-corresponding author RajaniSarojam “The results showed that the Raman spectroscopy-based method can swiftly detect and quantify innate immunity response in plants infected with bacterial pathogens. We believe that this technology will be beneficial for agricultural farms to increase their productivity by reducing their yield loss due to plant diseases.”
The scientists are presently dealing with the advancement of high-throughput, customized portable or hand-held Raman spectrometers that will permit Raman spectral analysis to be rapidly and quickly carried out on field-grown crops.
