Isothermal Amplification Techniques: An Emerging Tool for On-Site Detection of Phytopathogens in Field Conditions

This chapter reviews various isothermal amplification techniques, which are alternative to PCR for detecting plant pathogens. These methods, including NASBA, SDA, LAMP, HDA, and RPA, amplify nucleic acids at a constant temperature, making them potentially more suitable for point-of-care (POC) applications. The review compares these techniques regarding their mechanisms, advantages, and limitations, highlighting their potential for rapid, cost-effective, and on-site plant disease diagnosis, including the integration of these techniques with CRISPR-Cas systems and lab-on-a-chip technologies.
