• Root exudates in controlled environment agriculture: composition, function, and future directions (2025) · Frontiers in Plant Science · cited 31× · doi

  There is a lack of research on root exudates in CEA systems. Prior research has mainly focused on model plants and staple monoculture crops. There is a need to synthesize the existing literature to examine the composition, functions, and influences of vegetable root exudates within CEA systems.

• Root exudates in controlled environment agriculture: composition, function, and future directions (2025) · Frontiers in Plant Science · cited 31× · doi

  Quantifying and qualifying exudates is challenging due to the destruction of roots during exudate collection and contamination by other organisms in the rhizosphere. The paper identifies the need for further research on root exudates in CEA systems. It also highlights the challenges of working with CEA systems, including the need to balance substrate, biotic and abiotic stressors, nutrient availability, and microbial presence.

  Investigate the long-term effects of intercropping on root exudates and AMF colonization. Explore the mechanisms underlying the dominance of intercropping from the perspective of root exudates-soil microorganism interactions. Examine the impact of different intercropping patterns on root exudates and AMF colonization.
