Special Issue Information

Dear Colleagues,

Global warming and climate change are currently the two biggest challenges facing the agriculture sector. These lead to abiotic stresses such as heat, drought, salinity and temperature extremes that can significantly reduce plant growth and development. Fresh water supplies are predicted to further decrease in the near future, which will ultimately increase the intensity of abiotic stresses. Hence, there is an urgent need to increase the stress tolerance of plants. Phytohormones are chemical messengers that play an important role in enhancing plant resistance to biotic and abiotic stresses. These include auxin, gibberellin, cytokinin, abscisic acid, ethylene and salicylic acid. Phytohormones can trigger the plant antioxidant system and increase water content under severe drought stress. A strong signaling network exists and crosstalk among different hormones occurs during stress conditions. Phytohormones interact either by activating a second messenger or through a phosphorylation cascade. This regulates gene expression and directly affects the biosynthesis or action of different hormones and developmental processes in coordination with multiple stimuli.

The action of phytohormones through signal transduction, perception, and cross-talk creates a complex network that plays an essential role in the regulation of plant physiological processes. A better understanding of the mechanism of action of phytohormones and their roles in plant growth and development is essential for agricultural research and production. This includes an understanding of the interactions and independence of phytohormone action, as well as insights into the underlying mechanisms of stress tolerance in plants and of hormonal crosstalk under different stresses. The aim of this Special Issue is therefore to collect research papers and reviews that address these aspects of phytohormone action. The topics include, but are not limited to:

1.  Role of phytohormones in plant growth and development under stress conditions.
2. Crosstalk among phytohormones and stress tolerance in plants.
3. Interactions of phytohormones with other signaling molecules.
4. Crosstalk of phytohormones with cell signaling cascades.
