Plant stress response is the study of how plants react to various stressors in their environment, such as drought, extreme temperatures, salinity, pathogens, and pollution. When plants are exposed to these stressors, they activate a complex network of biochemical and physiological responses to protect themselves and maintain their growth and development. Researchers in this field investigate the molecular mechanisms underlying plant stress response, including the activation of specific genes and signaling pathways. They also study the role of various stress-responsive proteins, hormones, and secondary metabolites in helping plants cope with stress conditions. Understanding plant stress response is essential for developing strategies to improve crop resilience and productivity in the face of increasing environmental challenges, such as climate change and declining soil quality. Research in this area has practical implications for agriculture, forestry, and conservation biology.
