Abiotic stresses are constantly rising and pose a very high risk to global agricultural productivity and food security. Some plants have evolved several innate pathways for defense against these stresses. Hence, understanding stress signaling pathways can help develop crop plants with higher stress tolerance. The salicylic acid-mediated signaling pathway is important in plants experiencing biotic and abiotic stresses. In previous studies, SABP2-Interacting Protein (SIP-428) has been shown to be a negative regular of plant growth under abiotic stress. This study aimed to investigate the roles of SIP-428 in the ROS signaling of tobacco plants. We investigated transgenic RNAi-silenced lines of SIP-428 and wild-type tobacco plants for the activities of guaiacol peroxidase and catalase enzymes in Mannitol and NaCl-stressed plants for 7 and 14 days. Our results showed that SIP-428 plays a significant role in ROS signaling in Mannitol and NaCl-stressed plants via the activities of guaiacol peroxidase.
