Abstract :
Objective: This paper aims to explore the intricate role of plant hormones in mediating growth and development in response to various biotic and abiotic stimuli. By examining the signaling pathways involved, particularly in the context of jasmonic acid, the study seeks to enhance the understanding of hormone action and its implications for plant physiology and molecular genetics.
Methods: The review synthesizes current literature on plant hormone signaling, focusing on the characterization of mutants within hormone response pathways. It highlights methodologies used to dissect the molecular genetics of hormone signaling, including genetic, biochemical, and molecular approaches. The paper emphasizes recent advancements in understanding jasmonic acid signaling and its role in plant responses to environmental stresses and pest attacks.
Results: The findings indicate that plant hormones serve as critical chemical messengers that regulate diverse physiological processes. The characterization of hormone response mutants has revealed specific signaling pathways that translate external and internal stimuli into cellular responses. Recent progress in jasmonic acid signaling has uncovered its pivotal role in mediating plant defense mechanisms and adapting to environmental challenges, showcasing the complexity and specificity of hormone action in plants.
Conclusions: This paper offers a detailed overview of plant hormone signaling, emphasizing jasmonic acid. It discusses the role of mutant analysis in exploring the molecular genetics of hormone pathways, providing insights for future plant biology research and agricultural applications. The review highlights the necessity of understanding hormone signaling to develop strategies that enhance plant resilience against biotic and abiotic stresse.
