Effect Of Fungicide Pretreatment On Lipid Peroxidation, Antioxidant Enzyme Systems And Proline Accumulation In Tomato (Lycopersicon Esculentum Mill.) Leaves Under High Temperature Stress, Eli̇f Yüzbaşioğlu
Turkish Journal of Botany
The aim of the present study was to determine the effect of high temperature stress (HT) and to evaluate the protective role of fungicide pretreatment against HT stress in tomato leaves. The oxidative stress was triggered under HT stress through an increase in the content of malondialdehyde (MDA) and hydrogen peroxide (H2O2). Also, it caused a decline in photosynthetic pigments and enhanced the proline in tomato. However, the activities of catalase (CAT; EC 1.11.1.6), peroxidase (POX; EC 1.11.1.7), and glutathione S-transferase (GST; EC.2.5.1.18), as well as ascorbate-glutathione cycle enzymes (APX, EC 1.11.1.11, DHAR, EC 1.8.5.1, MDHAR EC 1.6.5.4, GR; EC …

Since plants are exposed to diverse environmental stresses in their natural area, numerous reviews have demonstrated many aspects of dehydrins (DHNs), including structural and functional dynamics, and multiple roles such as membrane protection, cryoprotection of enzymes, chaperone feature, and protection from reactive oxygen species. In this review, we have focused on new information, and other promising and emerging topics of DHNs in plants. This review outlines particularly the potential regulatory mechanisms of DHNs associated with stress tolerance and the role of DHNs in morphological responses of the plants exposed to environmental stresses. Besides the discussion of the signaling pathways involved …
