Understanding the mechanisms that regulate plant growth, development, and responses to environmental stimuli necessitates a deep knowledge of the complex signalling networks exhibited by plant hormones. This review aims to decipher the molecular underpinnings of these plant hormone signalling networks, particularly in response to environmental changes, a critical aspect in the context of climate change. The review employs interdisciplinary methodologies such as bioinformatics, systems biology, genomics, and proteomics to examine the intricate interplay and regulatory pathways that govern plant hormone responses. It focuses on key hormone families—auxins, gibberellins, cytokinins, abscisic acid, ethylene, and brassinosteroids—and elucidates their roles in various physiological processes, including senescence, cell division, elongation, and stress responses, all of which have implications for plant adaptation to changing climates. The paper addresses the identification and characterization of hormone receptors, transcription factors, and downstream signalling components that regulate hormone responses.

摘要

Understanding the mechanisms that regulate plant growth, development, and responses to environmental stimuli necessitates a deep knowledge of the complex signalling networks exhibited by plant hormones. This review aims to decipher the molecular underpinnings of these plant hormone signalling networks, particularly in response to environmental changes, a critical aspect in the context of climate change. The review employs interdisciplinary methodologies such as bioinformatics, systems biology, genomics, and proteomics to examine the intricate interplay and regulatory pathways that govern plant hormone responses. It focuses on key hormone families—auxins, gibberellins, cytokinins, abscisic acid, ethylene, and brassinosteroids—and elucidates their roles in various physiological processes, including senescence, cell division, elongation, and stress responses, all of which have implications for plant adaptation to changing climates. The paper addresses the identification and characterization of hormone receptors, transcription factors, and downstream signalling components that regulate hormone responses. It highlights the emerging function of hormone crosstalk and the interaction between hormones in determining plant growth and development, crucial for plants’ resilience in the face of climate change. Moreover, the review discusses the potential benefits of unraveling the molecular underpinnings of plant hormone signalling networks. These include enhancing crop yield, increasing resilience to stress, and promoting sustainable agriculture, all of which are vital for food security in a changing climate. This review as book chapter presents a comprehensive examination of the research article, shedding light on the current understanding and potential future developments in the field of plant hormone signalling. It underscores the importance of this research in understanding how plants can adapt to and mitigate the impacts of climate change, thereby contributing to the development of climate-resilient agricultural practices.
