Stress response analysis

Definition

Stress response analysis refers to the study of how organisms react to various stressors, including environmental, physiological, and biotic factors. This analysis helps to understand the metabolic changes and adaptations that occur in response to stress, which is critical in optimizing agricultural practices and improving food science outcomes. By examining these responses, researchers can develop strategies to enhance plant resilience, crop yield, and overall food quality under stressful conditions.
