Plant growth hormone production

Plant growth hormone production refers to the biosynthetic pathways and regulatory systems responsible for the synthesis of phytohormones, including auxins, gibberellins, cytokinins, abscisic acid, and ethylene. These signaling molecules are fundamental to plant physiology, governing processes such as cell division, elongation, tissue differentiation, and responses to environmental stressors (Davies, 2010). In agricultural and microbiological contexts, this production is a key trait of Plant Growth-Promoting Rhizobacteria (PGPR), which colonize roots and release hormones to enhance crop yield and resilience (MDPI, 2024). While certain phytohormones like abscisic acid are being investigated for potential cross-kingdom signaling and therapeutic effects in human conditions like diabetes and inflammation, the production process itself is primarily an agricultural target rather than a clinical one (PMC34896926). Drugs that interact with these pathways include herbicides and plant growth regulators (PGRs) such as 2,4-D, which mimics auxins to disrupt weed growth, and 1-methylcyclopropene (1-MCP), which acts as an ethylene antagonist to manage fruit ripening (Sensors, 2020). Because "Plant growth hormone production" describes a broad category of biological processes and enzymatic pathways rather than a discrete molecular target like a specific receptor or enzyme, it is not recognized as a standalone therapeutic target in drug discovery. Its relevance is centered on plant biology, agroecology, and the development of sustainable agricultural bio-inputs.

Plant growth regulators and herbicides targeting this process typically act as synthetic hormone mimics, inhibitors of biosynthetic enzymes (e.g., ACC oxidase), or antagonists of hormone receptors to modulate plant growth and development.
