Fig. 9From: Knockout of SlMAPK3 enhances tolerance to heat stress involving ROS homeostasis in tomato plantsA proposed model of the role of SlMAPK3 in tomato plants responses to heat stress involving ROS homeostasis. During heat stress, knockout of SlMAPK3 suppressed heat-induced upregulation of SlRBOH1 gene, and activated antioxidant enzymes, which alleviated ROS accumulation, in turn leading to a further mitigation in cell membrane damage in slmapk3 mutants. The involvement of SlHSFs/ SlHSPs genes expressions are also suggested by solid lines. Consequently, prolonged heat stress tolerance is inducedBack to article page
