Living organisms always need to confront biotic and abiotic stresses and this remains utmost important and evident in case of plants. Among the biotic stresses, plant diseases have played significant role in crop production. Many approaches have been accomplished for studying the nature of disease thus facilitating resistance development strategies. Large numbers of experiments have been conducted based on Pathogenesis-related (PR) proteins that bring about the plant defence response. Among the many PR genes, NPR1 (Non-Expressor of Pathogenesis) has been one of the important master regulator switch involved in stress responsive PR gene expression.
