Hormone Perception in Plants: Mechanisms and Interactions of Key Signaling Pathways

This article explores the intricate mechanisms of hormone perception in plants, focusing on the roles of brassinosteroids and their interaction with LRR-kinase domains. It also discusses the two-component histidine kinases and their involvement in cytokinin signaling and abscisic acid degradation. We examine the impact of gibberellic acid, ethylene, and auxin on plant growth and development, highlighting the significance of F-box E3 ubiquitin ligases and carboxylesterases in hormone regulation. Understanding these pathways enhances our knowledge of plant biology and their responses to environmental stimuli.
