Plant Hormones and Their Regulatory Roles in Abiotic Stress Response

Understanding the complex interactions between plant hormones and their corresponding signaling pathways is essential for enhancing plant resilience in challenging environments. This chapter provides an overview of these interactions, with a specific focus on the pivotal role of calcium in initiating downstream signaling pathways in response to abiotic stimuli. Additionally, the chapter investigates the interplay and examines the various functions of hormones, such as abscisic acid (ABA), jasmonic acid (JA), and ethylene, in plant growth, development, and defense against abiotic stress. It emphasizes the crosstalk between hormonal pathways and other signaling molecules within stress-signaling networks. The insights presented in this chapter contribute to the formulation of strategies for improving plant resilience and productivity.
