Plants are the primary producers of the Bioregenerative Life Support Systems. However, establishing sustainable agriculture on the Moon presents significant challenges due to the extreme abiotic stress conditions of the lunar environment. Moon soil (regolith) is characterized by poor nutrient availability and high levels of reactive oxygen species (ROS)-inducing elements, making it inhospitable for plant growth. Overcoming these limitations requires innovative strategies to enhance plant resilience and productivity. In this study, we investigated the effect of exogenous biotin identified via untargeted metabolomics on the growth, physiological responses and productivity of mung bean cultivated on moon soil simulant. Untargeted metabolomics analysis revealed that the biotin metabolism pathway was the most significantly downregulated pathway under moon soil simulant conditions. Exogenous application of biotin concentration of 1.0 mM significantly reduced oxidative stress, as evidenced by a decrease in lipid peroxidation levels and an enhancement of antioxidant enzyme activity; including catalase, ascorbate peroxidase, and glutathione reductase, compared to untreated controls. Total phenolic content and glutathione content were also enhanced at 1.0 mM biotin concentration. Biotin further improved nitrogen metabolism enzymes activity such as nitrate reductase, nitrite reductase, glutamate synthase, and glutamine synthetase. This treatment resulted in higher leaf nitrogen content and lower carbon-to-nitrogen ratio. Notably, 1.0 mM biotin treatment induced the most pronounced improvements, with net photosynthetic rate showing approximately 2.6-fold increase and pod yield 2.9-fold increase compared to controls. This is the first study to evaluate the role of biotin in mitigating abiotic stress and improving plant productivity on moon soil simulant, offering valuable insights for advancing space farming systems. © The Author(s), under exclusive licence to Council of European Aerospace Societies 2025.
