Role of triazolic compounds in underlying mechanisms of plant stress tolerance: A Review

Acclimation of plants to stress conditions depends upon activation of cascade of signaling networks involved in stress perception. Adjustment of antioxidant system to conserve a balance between the detoxification of reactive oxygen species and their production to preserve them at signaling level has been previously documented. Recently, the role of triazolic compounds like penconazole, paclobutrazole, triadimefon, and hexaconazole in the regulation of metabolic network under stress conditions emerge through crosstalk between chemical signaling pathways. Thus, stress signaling and metabolic balance are important areas with respect to increasing crop yield in adverse environmental conditions. This review outlines the recent advances on improvement in stress resistance by various triazolic compounds, aiming to identify new mechanisms of stress tolerance, and therefore, to contribute to sustainable crop yield under stress to bring some potential practical utilization in the future.
