Used in agricultural and plant biotechnology research to detect and quantify plant immune responses. Helps scientists study how plants react to pathogens such as bacteria, viruses, and fungi by measuring the levels of specific defense-related proteins or hormones. Enables high-throughput screening of plant varieties for disease resistance, supporting the development of resilient crops. Also applied in environmental stress studies to evaluate plant health under drought, salinity, or pollution conditions. Supports precision breeding and sustainable farming practices by providing insights into plant immune activation.
