From: Knockout of SlMAPK3 enhances tolerance to heat stress involving ROS homeostasis in tomato plants

Fig. 9

A 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 induced
