Light intensity drives the antibiotic resistome in plant-soil systems through plant-microbe molecular-metabolic networks and microbial community assembly

Key Points

• The antibiotic resistome is significantly shaped by light intensity in soil ecosystems, affecting microbial function.
• A notable shift in microbial community composition was observed with varying light levels, supporting the change in resistome.
• Analysis of plant-microbe interactions highlights critical metabolic networks that mediate this relationship across different soil types.
• These findings suggest that environmental factors, such as light, are crucial in understanding antibiotic resistance propagation in ecosystems.
