Integrated metabolomics and bioactivity analysis of Cynoglossum lanceolatum root extract as a natural inducer of resistance to rice bacterial blight

Background: Synthetic pesticides are widely used in agriculture to manage pests and reduce yield loss. Phytochemicals with antioxidant and antibacterial activities have great potential for treating plant diseases and reducing the use of synthetic chemicals. Identifying compounds from various plant species is crucial for their potential agricultural applications. Methods: root was tested for their polyphenol content, antioxidant potential, metabolomics and antimicrobial study. Results: lesions in pre-treatment and also showing their efficacy in post-treatment. Effect of extract was also observed in the photosynthetic status of rice by measuring chlorophyll A fluorescence. Conclusion: is a promising plant for its versatile role as an antioxidant, antimicrobial, and bacterial blight disease protection in rice.
