Summary

Hormones playa crucial role in the normal development of plants and their growth. Various plant hormones are synthesized by plants, such as auxins, cytokinins, ethylene, jasmonic acid, gibberellins, abscisic acid, etc. Ethylene is a plant hormone that regulates abiotic stresses, including wound healing, triggered by the plant and affects plant growth. This chapter summarizes the different abiotic stresses and the role of ethylene in controlling these stresses by metabolic reprogramming. We also discuss the signal pathways that contribute to overcoming these stresses. Abiotic stresses such as flooding, drought, temperature, and salinity are major constraints that affect plant growth, and ethylene helps overcome them by inducing genes. AP2/ERF (APETALA/ethylene response factor) is a special family of proteins that regulates plant growth and development processes in abiotic conditions through transcription factors. The Redox signaling under abiotic stress mechanism of hormone interaction in different stresses is summarized in the chapter.
