The Role of Plant Growth Regulators in Enhancing Agricultural Productivity: Biotechnological Perspectives

Abstract

Plant growth regulators (PGRs) play a crucial role in regulating various physiological processes in plants, ultimately impacting agricultural productivity. This paper explores the biotechnological perspectives surrounding the utilization of PGRs to enhance crop yields, improve stress tolerance, and optimize resource utilization in agriculture. It discusses the mechanisms of action of key PGRs such as auxins, cytokinins, gibberellins, abscisic acid, and ethylene, highlighting their effects on plant growth and development. Furthermore, it delves into recent biotechnological advancements in PGR research, including the development of genetically modified crops with altered PGR pathways for improved traits. The paper also addresses challenges and opportunities associated with PGR applications in agriculture, emphasizing the importance of sustainable practices for maximizing benefits while minimizing environmental impacts. Overall, this paper provides insights into the potential of PGRs as powerful tools for sustainable agricultural intensification in the face of global food security challenges.
