Abstract
En 中文
Climate change poses a major threat to global food security through extreme weather events, expanding pathogen ranges, and increased agrochemical dependency. This review highlights the emerging role of laser biotechnology as a sustainable and precise strategy to enhance crop resilience and productivity under climate stress. Laser-based approaches integrate both low-intensity photobiomodulation and high-intensity precision systems to regulate plant physiological, biochemical, and molecular processes. Low-intensity lasers significantly enhance seed germination, nutrient uptake, photosynthetic efficiency, and antioxidant defense while modulating stress-responsive genes and beneficial plant-microbiome interactions. In contrast, high-power laser systems provide chemical-free alternatives for selective weed eradication and pest management, reducing dependency on conventional agrochemicals. Laser-based sensing technology has also emerged enabling real-time monitoring of crops and early stress detection, which supports precision agriculture and controlled environment agriculture, such as plant factories. Although laser technology has considerable and transformative potential in sustainable agriculture, challenges remain regarding safety regulations, economic feasibility, large-scale implementation, and standardized irradiation parameters. Future work should involve validation in relation to growing crops in the field, exploring a wider range of combinations of wavelength and intensity with a variety of crops, and assessing the long-term agronomic and ecological implications of laser application. Collectively, laser biotechnology is a novel approach to sustainable agriculture and provides an avenue for climate-resilience food production while minimizing environmental impacts and improving food security globally.
